    Abstract: In today's increasingly demanding online world, one of the quickest ways to drive existing or potential customers and users to a competitor is by having a nonperformant website or app. With users becoming more discerning, you need to ensure that you're providing the best web experience possible. This reality has pushed performance optimization to be one of the most important disciplines in app and website development. Well-designed and smooth-performing apps and sites can lead to greater conversion rates and a better user experience (UX) in all contexts. In this video course, designed for intermediate-level developers with an understanding of HTML, CSS, JavaScript, and web technologies in general, your host Max Firtman, shows you some of the most important things you can do to boost the performance of your web assets. As the saying goes, you can't fix what you can't measure, so to begin, you'll learn the important metrics to monitor and how to measure them. Max also shows you how to set goals for your web content, find issues that can negatively affect UX, and apply some basic techniques that will improve user perception. You'll also benefit from practical examples and formative assessment to help you absorb and retain what you've learned. This video course is only the beginning of your optimization journey, so at the end we provide suggestions on how to continue along the path to delivering the best web assets you can. What you'll learn-and how you can apply it Set modern performance goals for your web content Detect problems and bottlenecks, and create a plan to mitigate them Enhance the user experience of your content, improving engagement and conversion rates Audit your website and web apps to see what's missing and how you can improve perception metrics This video course is for you because... You're a web developer or designer looking to increase user experience and perception You're a web performance engineer looking to understand the modern metrics and techniques You work with webs and PWAs looking to offer the fastest possible experience to your users You want to become a performance engineer looking to understand the basics of web performance optimization Prerequisites: You should have a basic understanding of HTML, CSS, and JavaScript You should have some knowledge of web technologies such as server-side rendering versus client-side rendering with JavaScript You should be familiar with how a website is rendered on browsers and how to u...

    Abstract: A major challenge architects face is planning how to successfully move an existing system to an improved architecture while keeping the system up and running during the process. Ray Mitchell (Fairway Technologies) reviews two real-world scenarios where failing systems were rescued by guiding development toward practical, improved architectures. You'll see examples of how different techniques and methodologies were applied to move real-world systems to new architectures while allowing for incremental improvements along the way. The first scenario focuses on a data aggregation system responsible for collecting power-usage data from a variety of sources to be consumed by multiple applications. The existing system suffered from a proliferation of services without clear responsibility boundaries. This limited scalability and made using the services more complex than necessary. Through domain-driven design, a more clearly defined organization became clear, and an incremental roadmap to move to this architecture enabled immediate gains and long-term success. The second scenario focuses on a reporting system built to provide insight into educational test results at both macro and micro levels. The original system struggled with scaling to generate reports within the required time frame at all levels. An architecture supporting separate optimized data stores for each level of report was designed that would enable all reports to run efficiently. Through careful planning, the existing system continued to deliver, as the improved architecture was incrementally added, allowing for improvements to be seen along the way. This session was recorded at the 2019 O'Reilly Software Architecture Conference in San Jose.

    Abstract: As teams and projects grow, code review becomes increasingly important to support the maintainability of complex code bases. But code reviews aren't as straightforward as they appear because the people involved in them aren't always predictable. Nina Zakharenko (Microsoft) dives deep into guidelines for writing consistent code, linting and analysis tools for various languages, and common code review gotchas. You'll learn about style guides and how they can help make your code more consistent and easier to maintain, as well as what tools are available to help automate the review process. You'll have better code reviews with your teams at work by giving code reviews with empathy using reviews as tools for sharing knowledge instead of turning the process into a competition. You'll also discover a better approach to code reviews in open source projects. What you'll learn Understand how to make reviews an opportunity for developers to learn from each other and encourage technical growth

    Abstract: Building microservices applications introduces more complexity into your architecture. Highly distributed applications on elastic, ephemeral infrastructure that communicate heavily over the network make for an environment where an application is always in a fluid, partially failing state at all times. To help developers transition from the monolithic way of designing and building software to a more service-oriented approach, we need to bridge the gap in tooling to help diagnose and understand what a normal state looks like and how to recover from a non-normal state. Mitchell Kelley and Scott Cranton (solo.io) discuss the types of failures that can occur, namely networking, application behavior/code, and storage, and present a systemic workflow for prodding and exploring a system to detect faults and abnormal behavior. This framework builds on the practices known as chaos engineering. Mitchell and Scott take a look at two open source projects that aim to complement this workflow: the Squash project, for step-by-step distributed microservices debugging, and Gloo Shot, a newly created chaos engineering framework. Prerequisite knowledge Familiarity with debugging applications and building distributed applications A basic understanding of services-oriented applications What you'll learn Understand chaos engineering Learn how to debug distributed applications with appropriate tooling Investigate the requisite workflow to apply toward system behavior exploration This session was recorded at the 2019 O'Reilly Open Source Software conference in Portland.

    Abstract: You built your system, you deployed it, you rolled it up in production, but it's just the beginning. The life of your system just started. It will grow, evolve, and wake you up in the middle of the night. Usually, at this point you start thinking about fault tolerance and error handling. Fault-tolerance concepts sound simple: modern frameworks promise to effortlessly solve it for you. But what's hiding behind the simplicity? Alex Borysov (Google) and Mykyta Protsenko (Netflix) take you along for a sneak peak at how to design and build truly fault-tolerant Java systems. They make it real by trying failure scenarios against a live system (you'll watch it recover in real time) and then review the recipes (with gRPC and REST examples and a number of open source tools) that you can use right away to make your code more resilient and your system more robust. Prerequisite knowledge A basic understanding of microservice architecture This session was recorded at the 2019 O'Reilly Open Source Software conference in Portland.

    Abstract: As our industry matures, there's been an evolution in attitude toward design. From Google to startups, there's a burgeoning belief that the competitive advantage lies in user experience. That said, most of us don't work with trained user experience designers. On small or dev-focused teams, we need to be scrappy, and often it's developers and engineers who make crucial user experience decisions-from workflows to errors to labels. Regardless of your team composition, having some rock-solid user experience principles will help improve the products you build and make your users' wildest dreams come true. Okay, maybe that's a stretch, but they'll definitely be glad you're willing to give them some love. Josh Clark and Mike Biglan (Twenty Ideas) give you some tools to use so that you, as a developer, can be a UX beast. They explore how to nurture curiosity as a means of understanding the user; how to leverage psychology, including decision science, in the process of developing workflows; how to communicate and argue well; and how to become a UX developer unicorn-winning friends and influencing people (including your boss) to become a more valuable and critical member of any team. Prerequisite knowledge Experience developing products What you'll learn Understand what UX is, why it's important, and how to think about UX front and center and work with experienced UX designers This session was recorded at the 2019 O'Reilly Open Source Software conference in Portland.

    Abstract: Many presentations on microservices offer a high-level view of the architecture; rarely do you hear what it's like to work in such an environment. Individual services are somewhat trivial to develop, but now you suddenly have countless others to track. You'll become obsessed over how they communicate. You'll have to start referring to the whole thing as "the Platform." You'll have to take on some considerable DevOps work and start learning about deployment pipelines, metrics, and logging. Don't panic. Stephen Pember (Toast) shares what he's learned over the past six years migrating from a monolith to microservices across several companies. He examines what a development lifecycle might look like for adding a new service, developing a feature, or fixing bugs. You'll see how team communication is more important than one might realize, as coordinating on architecture designs and implementation is crucial. Most importantly, he'll show how-while an individual service is simple-the infrastructure demands are now much more more complicated: your organization will need to introduce and become increasingly dependent on various technologies, procedures, and tools ranging from the ELK stack to Grafana to Kubernetes. You'll leave understanding why your resident SREs should be the most valued members of your team.

    Abstract: Kubernetes namespaces partition workloads into virtual clusters so multiple teams or applications can safely share a physical cluster. Today, there is no common consensus on how to use Kubernetes namespaces and namespaced objects in relation to identity, resource limits, and security. As the number of teams, clusters, and namespaces grows within an organization, it becomes increasingly difficult to maintain any kind of coherence. Amy Chen (VMware) discusses how, by aligning identity, resource limits, and your application's security posture, cluster operators can get more organizational mileage out of Kubernetes namespaces. She walks you through common scenarios of how organizations use namespaces today; breaks down namespaces in relation to your workloads and users; compares various approaches to namespace management; shows how to enforce RBAC, resource limits, and your application's security posture within namespaces; and outlines friction in existing namespace management workflows.

    Abstract: Security concerns are often dealt with as an afterthought-the focus is on building a product, and then security features or compensating controls are thrown in after the product is nearly ready to launch. Why do so many development teams take this approach? For one, they may not have an application security team to advise them. Or the security team may be seen as a roadblock, insisting on things that make the product less user friendly, or in tension with performance goals or other business demands. But security doesn't need to be a bolt-on in your software process; good design principles should go hand in hand with a strong security stance. What does your engineering team need to know to begin designing safer, more robust software from the get-go? Drawing on experience working in application security with companies of various sizes and maturity levels, Wendy Knox Everette (Leviathan Security) focuses on several core principles and provides some resources for you to do more of a deep dive into various topics. Wendy begins by walking you through the design phase, covering the concerns you should pay attention to when you're beginning work on a new feature or system: encapsulation, access control, building for observability, and preventing LangSec-style parsing issues. This is also the best place to perform an initial threat model, which sounds like a big scary undertaking but is really just looking at the moving pieces of this application and thinking about who might use them in unexpected ways, and why. She then turns to security during the development phase. At this point, the focus is on enforcing secure defaults, using standard encryption libraries, protecting from malicious injection, insecure deserialization, and other common security issues. You'll learn what secure configurations to enable, what monitoring and alerting to put in place, how to test your code, and how to update your application, especially any third-party dependencies. Now that the software is being used by customers, are you done? Not really. It's important to incorporate information about how customers interact as well as any security incidents back into your design considerations for the next version. This is the time to dust off the initial threat model and update it, incorporating everything you learned along the way.

    Abstract: DevOps and platform teams have too many projects, not enough time, and users who are an email, message, or quick walk away to tap you on the shoulder to ask if that thing is done, because "it's really holding them up from completing something for real this time." James Heimbuck (SendGrid) shares some tried-and-true product management practices that help solve the problems of never-ending projects, squeaky wheels that demand priority, and projects that flop on launch. James discusses common product practices and the experience of introducing those at SendGrid in the tech ops org, including validating problems through customer interactions, using story maps to get to first-and-fast release, launching products for adoption, getting user feedback and incorporating it into the backlog, and sunsetting a product.

    Abstract: It's widely recognized that monitoring is a critical aspect of operating a service, but the practice of observability is still relatively nascent in most organizations. While monitoring can indicate a problem, it's only by making systems observable that teams can understand the behavior of complex systems, isolate causes, and effectively remediate incidents. The resulting insights provide value that extends far beyond the ability to successfully operate systems. Deeper knowledge of system behavior can inform and focus future development efforts, or quantify the value and effect of more recent work. Rajesh Raman dives deep into the practice of observability, demonstrating how a more analytics-driven approach to metrics, traces, and other monitoring signals improves observability. You'll learn a framework for kick-starting a culture of observability in your organization, informed by Rajesh's experience building and deploying observability tools at SignalFx. This session is sponsored by SignalFx.

    Abstract: Software architecture is a young and curious discipline. While analogizing software architecture with building architecture and city planning can be useful, it can also be misleading. Physical structures benefit from up-front design to guide their development, but software systems have a more dynamic nature that requires additional foresight. Systems thinking is a maturing field that examines the structure and behavior of complex systems, how they develop, and how they may be influenced (but never controlled). Matt McLarty (MuleSoft) explores how systems thinking can be applied to software architecture. You'll gain an introduction to systems thinking concepts and axioms, such as the iceberg model, the bathtub theorem, stock and flow diagrams, and more; an analysis of enterprise software ecosystems from a systems thinking perspective; and systems thinking-inspired techniques software architects can use when designing or evolving these software ecosystems through the use of microservice architecture and APIs.

    Abstract: EOSDIS is working toward a vision of a cloud-based, highly flexible system to meet its ever-growing and evolving data demands. Cumulus, a free and open source framework, supports this vision via configurable workflows to ingest, process, archive, manage, and distribute NASA's Earth imagery. The Cumulus infrastructure is designed for scalability and reliability, using much of the AWS serverless platform, which enables Cumulus to scale in real time to be performant under the largest expected workloads. Cumulus is poised to make a huge impact on how NASA manages and disseminates its Earth science imagery. In one notable case, the NASA-ISRO Synthetic Aperture Radar (NISAR) mission, Cumulus will be used to collect more data in a year than exists in NASA's current archive. The NISAR mission will collect 45 PB a year and process that data at a rate of 1 GB per second. The need for Cumulus is proven through its application to NASA missions, but its application has extended beyond NASA's Distributed Active Archive Centers (DAACs). It's being used to monitor agriculture in Tanzania, apply machine learning models to estimate hurricane intensity, and generate air quality predictions using near-real-time forecast data. Aimee Barciauskas (Development Seed) outlines the motivation for Cumulus, the achievements and hurdles of the past two years, and its varied applications. You'll learn about the availability of the open-sourced software and how NASA intends to make its Earth Observing Geospatial data available for free to the public in the cloud.

    Abstract: More and more, Allen Holub (Hollub Associates) has come to see event storming as a critically important tool in the architect's palate. It's a way to simultaneously collaborate with businesspeople to understand the problems that the business has to solve and develop an architecture for the solution. Join Allen for an in-depth look at event storming and its underlying concepts (from DDD), as well as an extensive hands-on demo of the process. Along the way, you'll discover the entities, bounded contexts, and events that are essential for an effective choreographed microservice (or reactive) architecture. You'll come away from this talk with a solid understanding of how event storming works and how to apply it.

    Abstract: Describing software or IT architectures and effectively communicating about architecture to (business) stakeholders is a relevant and important skill for all architects. Many architects can advance in that skill, since communicating (about) architecture is hard, especially to nontechnical stakeholders. Jochem Schulenklopper (Xebia) dives into theory, practice, and examples; he presents relevant theories, techniques, and examples of creating architecture visualizations that are attractive, informative, and easier to understand for nontechnical audiences. Visual communication (on architecture) has many facets to look at and can take many forms. Jochem touches upon theory, examples (and some not-so-great examples), and practical advice on each of those facets: basic visual attributes, composition/layout, color, text, graphs, sketches, icons, images and pictures, and storytelling.

    Abstract: It's two minutes and five seconds after midnight on November 11, 2018; that's how long it took for the Alibaba platform to record RMB 10B worth of sales. At the 26 minute and 2 second mark, more than RMB 50B of goods were sold, and by the end of the day, a total of RMB 213.5B of goods were sold-the equivalent of $30.5 billion. Over half a billion people across 200 countries participated in this event with goods purchased from 180 thousand brands. Clearly, not only did a massive number of transactions take place in a short period of time, but a massive number of users were also concurrently browsing product information. At one point, the system reached 1.72B messages per second. And later that day, over 1B packages were shipped out to the buyers. Alex Chen (Alibaba Cloud) examines how a combination of cloud native storage products such as table storage, object storage, and log storage combined with serverless technologies were the backbone supporting such a massive workload.

    Abstract: Building intermicroservice communication over the network is one of the hardest things in building microservices. The resiliency of microservice-based applications heavily depends on how well they handle interservice communication over an unreliable network. To make microservices resilient, the developers have to apply numerous resiliency patterns such as timeout, retry, circuit breaker, fail-fast, bulkhead, transactions, and failover/load balancing. Most of these patterns are implemented as part of the service logic, and microservice development technologies have to cater to such requirements. On the other hand, service meshes try to offer such commodity features as part of a shared communication infrastructure. Kasun Indrasiri (WSO2) explores the importance of microservice resiliency; details resilience patterns for interservice communication, including timeout, retry, circuit breaker, fail-fast, bulkhead, transactions, and failover/load balancing; dives into transactions resiliency; discusses technologies for building resilient microservices; and outlines the role service meshes play in building resilient microservices communication.

    Abstract: The number of microservices running in enterprises increases daily. As a result, service composition, governance, security, and observability are becoming a challenge to implement and incorporate. A cell-based architecture is an approach that can be applied to current or desired development and technologies to address these issues. This technology-neutral approach helps cloud-native dev teams become more efficient, act in a more self-organized manner, and speed up overall release times. Asanka Abeysinghe offers an overview of a cell-based reference architecture that is API-centric, cloud native, and microservices friendly. You'll learn the role of APIs in the cell-based approach and examine how real applications are built as cells. Along the way, Asanka explores metrics and approaches that can be used to measure the effectiveness of the architecture and demonstrates how organizations can implement the cell approach. This session is sponsored by WSO2.

    Abstract: As you level up in technical roles, you may find yourself thrust into team leadership and management. This sneaks up on you and can leave you without the skills to adequately understand, engage with, and lead your team-which inevitably has a negative effect on your team, and this effect is multiplied as you scale. What if you could reach into the toolbox you use to understand technical problems-software architecture and distributed systems theory-to understand your team? Could you learn to better manage people? Andrew Harvey (Microsoft) explores the dynamics of teams and how they map to your understanding of distributed systems. Using this understanding, you can apply distributed systems theory to help unpack some of the dynamics of your team and optimize them for scale. From communication to culture, Andrew breaks down the components of the distributed system, explaining what makes it tick, using things like CAP theorem and the eight fallacies of distributed systems. You'll walk away with some tools to help understand your team and set yourself up for successful scaling. This session was recorded at the 2019 O'Reilly Velocity Conference in San Jose.

    Abstract: The last two decades have seen evolutions of software architecture-from on-premises to cloud hosted to mass-scaled microservices. While cloud native applications look very different than something we may have built before some of these techniques were well known, at their heart are still long-running, custom-built server applications that orchestrate the flow of requests, data, and logic. Serverless changes all of this. We no longer build always-on server applications; we rely on events as the agents of flow rather than requests, and the server-side software that we do write may be a small aspect of our system rather than the central hub. Fundamentally, serverless is about choreography of multiple services from multiple teams and vendors-in extreme situations-none of which we have written ourselves. Mike Roberts (Symphonia) introduces some of the patterns, or "common solutions to recurring problems," that we are starting to see in the serverless community. Patterns are not necessarily best practices-they are techniques that have worked for many people, but always given certain contextual constraints. Perhaps even more importantly, however, Mike describes how you, your teams, and your organizations can start harvesting your own patterns, while the bigger industry learns more about this exciting new frontier. This session was recorded at the 2019 O'Reilly Software Architecture Conference in San Jose.

    Abstract: Academic machine learning almost exclusively involves offline evaluation of machine learning models. In the real world this is, somewhat surprisingly, only good enough for a rough cut that eliminates the real dogs. For production work, online evaluation is often the only option to determine which of several final-round candidates might be chosen for further use. As Einstein is rumored to have said, theory and practice are the same, in theory. In practice, they are different. So it is with models. Part of the problem is interaction with other models and systems. Part of the problem has to do with the variability of the real world. Often, there are adversaries at work. It may even be sunspots. One particular problem arises when models choose their own training data and thus couple back onto themselves. In addition to these difficulties, production models almost always have service-level agreements that have to do with how quickly they must produce results and how often they are allowed to fail. These operational considerations can be as important as the accuracy of the model: the right results returned late are worse than slightly wrong results returned in time. Ted Dunning (MapR) offers a survey of useful ways to evaluate models in the real world, breaking the problem of evaluation apart into operational and function evaluation and demonstrating how to do each without unnecessary pain and suffering. You'll learn about decoy and canary models, nonlinear latency histogramming, model-delta diagrams, and more. These techniques may sound arcane, but each is simple at heart and doesn't require any advanced mathematics to understand. Along the way, he shares exciting visualization techniques that will help make differences strikingly apparent. This session was recorded at the 2019 O'Reilly Strata Data Conference in San Francisco.

    Abstract: WebAssembly is a powerful tool for porting applications to the web and for speeding up data-intensive web apps. If you don't know what WebAssembly is, how it works, or how to practically get started using it, now's your chance. Robert Aboukhalil (Invitae) leads a deep dive into WebAssembly, demonstrating how it can be used to speed up web tools. As a concrete case study, he'll use fastq.bio, a web tool for analyzing DNA sequencing data in the browser. By rewriting portions of this tool into WebAssembly, he demonstrates how it's possible to obtain a greater than 10x speedup compared to the original JavaScript implementation. Robert will also show you how to leverage WebWorkers alongside WebAssembly to maintain the UI's responsiveness and how this enables you to more easily mount and parse files within a virtual filesystem. He concludes by exploring how WebAssembly can be useful outside the browser-demonstrating how it's possible to rearchitect fastq.bio so that the WebAssembly code runs in a serverless fashion instead of directly in the browser. And because WebAssembly isn't always the right tool, Robert also explores some rules of thumb on when to use WebAssembly and when to avoid it. Prerequisite knowledge Intermediate knowledge of JavaScript What you'll learn Understand what WebAssembly is and how it works Learn to compile C/C++ code to WebAssembly and run it in the browser, use WebWorkers to run computations in the background, and run WebAssembly in a serverless setting Know when to use WebAssembly and when to avoid it This session was recorded at the 2019 O'Reilly Open Source Software conference in Portland.

    Abstract: When it comes to digitally recording and storing valuable information, no other technology can match the strength of security of the blockchain. Blockchain's distributed-ledger technology offers near immutable record keeping for transactions of all kinds, including legal contracts, property deeds, registrations, financial matters, birth certificates and other personal information, municipal archives, important business data, or any other types of activity for which inviolable records must be maintained. Of course, most people associate blockchain with cryptocurrency, but this fascinating technology is capable of much, much more. Ethereum represents the second-generation in the public blockchain, In addition to offering its own cryptocurrency (Ether) Ethereum's second-generation architecture allows it to manage many other types of assets. In this course, designed for participants who have a basic understanding of programming languages such as Java, Python, and JavaScript, and who know how to use web-based applications, your host, blockchain and Ethereum expert, Jim Sullivan, introduces you to the Ethereum network. You'll learn how it works and examine ideas like blockchain consensus, the essential concept at the core of blockchain's reliability and integrity. Jim also presents the tools you'll use to manage your Ethereum environment. You'll explore the differences between first- and second-generation blockchain technology and see how Ethereum nodes can run programming code called Smart Contracts, which you can set up to take actions on Ethereum transactions. In addition, Jim teaches you about designing and building Decentralized Applications or DApps, and much more. You'll benefit from the hands-on approach of this video course, which includes use cases to reinforce what you learn and get you started on your way toward developing enterprise Blockchain applications using Ethereum.

    Abstract: Christie Koehler (HashiCorp) takes you through the fundamentals of Terraform as she uses it to deploy cloud infrastructure live. You'll orient yourself to the current state of the infrastructure as Christie open as a cloud shell and inspects the Terraform state file, then makes some changes to the Terraform configuration, which deploys a new pod and configures a web service for that pod. Terraform plan with those changes, review the plan, and apply. Take a look with Christie at the Kubernetes dashboard to verify the changes have been made, and review and approve a pending pull request to the Terraform configuration that sets up a simple serverless app in the cloud infrastructure. As before, Terraform plan with those changes, review, and apply. Then take a look at the cloud provider dashboard to verify the serverless function or application has been deployed, and test it. If there's time, Christie will walk you through how to detect and manage drift (i.e., when infrastructure changes outside of Terraform). This session was recorded at the 2019 O'Reilly Open Source Conference in Portland, OR.

    Abstract: One of the most challenging aspects of microservice architectures is selecting the right infrastructure to make your services work seamlessly and effectively. What frameworks, tools and managed services will you select to build, package and deploy your services, manage connections, monitor, and, most importantly, protect and leverage your data? Your choices include open source solutions, enterprise versions, and cloud service providers. Things only get more confusing when you realize that you might be one acquisition or business decision away from needing to architect a hybrid cloud or multicloud solution. Jeff Carpenter details specifically the use of technologies for persisting and moving data in microservice architectures. He examines the concept of "polyglot persistence" and the proper usage of different styles of databases, caches, and streaming solutions. You'll consider effective patterns for combining these technologies, using Apache Cassandra and Apache Kafka as examples. This session is sponsored by DataStax.

    Abstract: Application security testing has been around for a long time, yet successful attacks continue despite significant investments in application security. And we shouldn't be surprised when we're applying testing tools developed more than 12 years ago to software development methods only made commonplace in the last 3-5 years. In addition, application security is least understood and often takes a back seat to perimeter and endpoint security. At the same time, there's a misconception that the cloud provider takes care of all the security, and few people have considered new attack surfaces introduced by containers and orchestration. Tesla showed us the fallacy here. Traditional application security testing has been targeted to security professionals and is regarded as a separate process from development. This separation and delay creates friction in the process, with many trade-offs required. In an effort to improve application security testing, the new chant has been "shift left" to remove more vulnerabilities earlier and empower the developers. Lucas Charles (GitLab) examines the shortcomings of most shift-left efforts and how cloud native environments, Agile DevOps processes, and minimum viable products with rapid iteration wreaks havoc on traditional security methodologies. He dives into how to bring security into DevOps while avoiding a complex DevOps toolchain that must be integrated with security testing and explores new ways of thinking of app security to turn the industry on its head by using concurrent DevOps-a method that makes it possible for product, development, QA, security, and operations teams to work at the same time. You'll learn the three key requirements of your application security process needed to get you onto the road of an efficient and secure software development lifecycle (SDLC).

    Abstract: With the technology available today, it isn't hard to build applications fast that are scalable and resilient. Tanmai Gopal (KintoHub) live-codes the backend of an app with real-world business logic, using the best-of-breed technology from the open source and cloud ecosystem. The three factors of this backend are real-time GraphQL, eventing, and serverless. Without diving into explanations of what the technologies are or how they work, you'll learn the power of this three-factor architecture and its tangible impact on feature velocity as Tanmai builds the backend before your eyes. You'll then help test the app by placing orders simultaneously to understand how this architecture enabled scalability without any effort. Tanmai will cause network failures between the different components of the backend as your orders are being processed to show how the event-driven approach allows for built-in reliability. Prerequisite knowledge Familiarity with the basics of building and operating a backend for web/mobile applications Hands-on knowledge of APIs, databases, and deploying code (useful but not required)

    Abstract: Microservices and containers have taken the software industry by storm. Transitioning from a monolith to microservices enables you to deploy your application more frequently, independently, and reliably. However, microservice architecture has its own challenges, and it has to deal with the same problems encountered while designing distributed systems. Enter service mesh technology to the rescue. A service mesh reduces the complexity associated with microservices and provides functionality like load balancing, service discovery, traffic management, circuit breaking, telemetry, fault injection, and more. Istio is one of the best implementations of a service mesh at this point, while Kubernetes provides a platform for running microservices and automating deployment of containerized applications. Join Samir Behara (EBSCO) to go beyond the buzz and understand microservices and service mesh technologies. This session was recorded at the 2019 O'Reilly Software Architecture Conference in San Jose.

    Abstract: When creating a continuous delivery pipeline, many strive only to automate what they're already building instead of taking another look at old assumptions. When your goal is to deploy once a quarter, you may choose an architecture with tightly coupled services or components. If your goal is to be able to deploy on demand, this same architecture may be getting in your way. Join Ken Mugrage (ThoughtWorks) to discover how changing the architecture of your system to enable faster delivery can be more beneficial and stable than trying to automate deployment for systems that weren't designed for it. Closely related to the ability to deploy the application on demand is the ability to make sure it's doing what we expect it to every time. Acceptance tests, especially when browser based, are often considered so fragile that many organizations have simply stopped doing them. Ken shows you how to make architectural decisions that will make it easier to write and maintain quality-acceptance tests.

    Abstract: Deciding what to work on is always difficult and is especially treacherous for folks working as infrastructure engineers and leaders. Infrastructure teams that solve the right problems subtilely shift their company's trajectory upwards. Poor approaches lead toward a morass of firefighting and frustration. With so many opportunities and sometimes fuzzy metrics, planning is threading a needle between the tyranny of choice and the specter of ambiguity. Will Larson (Stripe) unpacks the process of picking and prioritizing technical infrastructure work, which is rarely if ever discussed but is so essential to long-term company success. Will shares Stripe's approach to evolving your approach to prioritizing infrastructure as your company scales, justifying-and maybe even expanding-your company's spend on technical infrastructure, exploring the whole range of possible areas to invest into infrastructure, adapting your approach between periods of firefighting and periods of innovation, and balancing investment in supporting existing products and enabling new product development. You'll come away with a broad set of tools, frameworks, and ideas for plotting the future of your technical infrastructure. This session was recorded at the 2019 O'Reilly Velocity Conference in San Jose.

    Abstract: Unlike a monolith, which is an independently deployable unit that can be tested as a whole, microservices are a distributed system, composed of many services that can be tested and deployed independently of each other. While this approach has many advantages, from a testing perspective it can actually make things harder. How do I know the impact of changing or deploying a microservice on other microservices that may depend on it? Andrew Morgan dives into common microservices testing anti-patterns, including building an end-to-end testing microservices like a monolith, the "distributed monolith" anti-pattern, and unit tests that are heavily reliant on stubs of other microservices that may be inaccurate or stale. He then offers an overview of consumer-driven contract (CDC) testing-a TDD at the API level approach to microservices-as a way to mitigate them. Andrew walks you through the concept end to end, explaining how to use it to guarantee that both message-driven and API-driven interactions between microservices will work without end-to-end testing, provide a fast and reliable feedback loop for microservices development, and deliver independently testable and releasable microservices.

    Abstract: Technical debt is a funny thing. While the term attempts to make an analogy with financial debt, technical debt and financial debt have nothing in common. Instead, it's the name we give engineering decisions we disagree with. Robert "r0ml" Lefkowitz (Retired) offers an overview of technical debt, explaining how to recognize it, how to prevent or reduce it, and how come we see so much of it. Many so-called best practices today, are, in fact, technical debt factories. The reason we have so much of it is that we eagerly create it at earlier stages of an organization and fail to alter our approaches soon enough when the organization matures, and these early practices which were "investment" become "debt." Robert discusses many of these practices. One of these is microservices-often undertaken as a technique for increasing agility, at the cost of manufacturing tech debt. Robert details common methods for avoiding increasing the tech debt burden by deploying microservices. Robert explores two primary themes that apply to multiple software methods. The first is the principle of parsimony, which dates back to the ancient Greeks but was popularized more recently by the 12th century theologian William of Ockham. The second theme is the doctrine of immutability. This idea, too, flowered during the Middle Ages and is enjoying a renaissance today with the rise of functional programming languages. Robert dives into both of these ideas as they apply to data types, programming languages, network protocols, software dependencies, configuration management, and more. This session was recorded at the 2019 O'Reilly Software Architecture Conference in New York.

    Abstract: The transformative benefits gained in evolving from a project to product mind-set should not only be for the devs. In today's digital age, it is more important than ever for the infrastructure itself to be fast, fully automated, self-healing, and scalable to meet the ever-changing business demands. The move to the cloud provides these capabilities, but the real transformation is in the people. Infrastructure teams and their traditional silos across the enterprise must transform to measure their people in terms of their collective contributions to a shared goal rather than by their efforts. This value can only be realized by changing from a project to a product mind-set. Heather Martin (Discover) walks through the journey that started with automating everything in Discover's traditional infrastructure through the capabilities of the cloud to a more valuable shift in treating the infrastructure as a product. The shift to a product-centric organization has allowed Discover to move from a less valuable traditional functional model to one that is agile and focused on delivering business outcomes and capabilities that provide real value that can help anticipate customer needs. Heather reveals how invoking a shared responsibility model and absorbing and evolving needed product characteristics allowed the company to move faster and made its platforms and services more resilient and relevant and how this shift allowed the company to gain insight and fast feedback to develop and quickly deliver a better and more meaningful product. Most importantly, now being able to focus people on value-added work, rather than toil, allows increased business agility to give Discover an advantage over its competitors. The road has had its fair share of bumps and, at times, potholes that almost swallowed the team up. Discover is a company of very tenured technologists that have at times been extremely resistant to change. The technology is easy; it's the people that are hard, and Heather's team has the bruises to prove it. So she shares the lessons learned in the hope you won't make the same mistakes and that you can accelerate your own journey. She provides you with the perspective and guidance to get started, quickly mature, get unstuck, and find yourself delivering infrastructure with more value and intention than ever before.

    Abstract: Kubernetes is all the rage these days and for good reason. Among other benefits, app development teams get to use battle-hardened infrastructure to build and deploy containers, use modern tech and practices, and lower their cloud bill. But these days, the journey to Kubernetes is long and hard. Aaron Schlesinger (Microsoft) dives into case studies that reveal the general needs of many app developers. He uses these case studies to build a long list of concepts and technologies you need to learn before you can even think about deploying your apps on Kubernetes. You'll learn his strategies (and hacks and shortcuts) that teams have used to get up and running faster. Aaron helps you shorten that long list, eases your transition, and makes the day-to-day life of app developers easier on Kubernetes. Gain a holistic view of your team's needs and how you can help them, and leave with a deep understanding of what your teams need to succeed on Kubernetes, important tools you can use to help them, and how you can use them today to realize the benefits that Kubernetes can bring to your apps right now.

    Abstract: Blockchain technology is among the most exciting developments in the IT industry in many years. Often shrouded in mystery (including who the person is who developed it), today blockchain is most well known as the technology that underpins cryptocurrencies, the most famous of those being Bitcoin. But blockchain's distributed-ledger technology holds the promise to revolutionize the way businesses and governments create and maintain important records of transactions of all kinds, whether it's contracts, deeds, or any other types of activity for which an inviolable record must be maintained. In this video course, intended for developers and programmers who have a basic understanding of web-based applications, you learn the fundamentals of a blockchain and Decentralized Applications, or DApps, and how data that's stored there is considered immutable-all but impossible to tamper or change, and if an attempt were made, it would be detected immediately. You'll begin by learning blockchain's terminology and then explore how it's used in cryptocurrency. You'll also look at blockchain deployment models, Consensus Algorithms, blockchain supply chain models, DApp modeling and development, as well as development environment requirements for blockchain coding. You'll examine the theory and concepts such as how many distributed computer hosts, called nodes, add bits of information in "chains" of highly encrypted blocks. When you've completed this video course, you'll have a firm understanding of blockchain basics and a solid foundation from which to continue learning and dive deeper into this fascinating field. What you'll learn-and how you can apply it The history of Bitcoin and blockchain technology Technical structure of a Blockchain Basics of how a blockchain works and it architecture Basic understanding of blockchain use cases in business How hashing algorithms work Understand Decentralized Applications, or DApps, architecture and design Migrate centralized database systems into DApps Understand how blockchain manages assets such as cryptocurrencies, and other assets Build an end-to-end transaction flow for blockchain supply chains Basic understanding of cryptography via hands-on exercises The development environment and requirements for blockchain application development This video course is for you because... You want to understand the use cases for blockchain and resources to help get started in the blockchain space You want to "get ahead of the curve" ...

    Abstract: Architects are leaders. We need to understand our business, our users, and our ecosystem. We need to effectively interact with our stakeholders, productively collaborate with design and product teams, and give direction and motivate our development teams. Achieving these goals requires much more than technical excellence. Drawing on material he's used to train team members ranging from developers and designers to executives, Seth Dobbs (Bounteous) offers a primer on leadership for architects, focusing on guiding principles that are easy to learn and put into practice. Principles will cover both inward focus (personal mastery) and external focus (effective interactions) and will include topics such as vision, problem solving, ownership, and conflict. Seth introduces each principle first with a problem or anti-pattern, discusses the principle, and then details examples of the principle in practice. Whether you're new in a leadership role looking to understand the "soft" skills required or have been leading for a while and want to formalize your thinking on leadership, this session is for you.

    Abstract: Recent discussions about service mesh have been dominated by vendors, each trying to frame service mesh as a new technology that provides security, reliability, and observability for east-west traffic. However, just as microservices are an architectural pattern and not a specific technology, service mesh is a new way to deploy features that in the past fell into the category of API management. In a service mesh, a proxy is deployed locally with each service in an application. Each service only communicates directly with the proxy on its host, and proxies communicate with each other to pass traffic between services over the network. Marco Palladino (Kong) explores the service mesh pattern and discusses the problems the pattern is designed to solve, including security (proxies can encrypt all network traffic without services being aware of it), observability (proxies collect metrics, logs, and tracing data from network traffic), reliability (proxies can enforce rate limiting, retries, and handle network drops), composability (swap or reuse services with nothing but a proxy configuration change), standardization (east-west traffic can all be secured in the same way), and efficient development (service developers can focus on business logic instead of interservice communication). Finally, he explains the requirements for any technology that supports this pattern: services can be any size, in any language, or run on any infrastructure or a mix; proxies need to be lightweight, since an instance will be deployed with each service; proxies should be flexible and composable to provide security, reliability, and observability benefits; proxies should be simple to deploy and replace in containerized environments; and proxies should be self-reliant and resilient to network slowdowns and failures. This session was recorded at the 2019 O'Reilly Software Architecture Conference in San Jose.

    Abstract: Data science, visualization, and artificial intelligence are powerful tools, but they can reinforce structural inequalities like sexism and racism. How do we-CTOs, product managers, marketing managers, data scientists, developers, and others-navigate these ethical challenges? The short answer: feminism-a vibrant body of thought and action from the past 50+ years that provides a model for analyzing and addressing the unequal distribution of power in the world as well as working toward data fairness. In this Spotlight on Data , Catherine D'Ignazio and Lauren Klein discuss key concepts from their forthcoming book, Data Feminism (MIT Press, 2020), which applies feminist ideas to data science and outlines seven principles for using data in the service of greater justice. You'll learn what "data feminism" means, how to evaluate your data practices through a feminist lens, and why feminism is not just for, about, or by women. You'll also discover how the principles of data feminism apply to different stages of the data processing pipeline, from project inception to collection to cleaning and analysis to communication.

    Abstract: A lot has been said about the SRE profession (how to start an SRE team, how to scale a single team in place, etc.), but how to move from a single SRE team to an SRE organization that requires several teams has been largely unexplored. Gustavo Franco (Google) takes new SRE leaders and individual contributors through what it takes to be a part of or start their second team and beyond. Join in to learn from his experience starting new teams and splitting and moving them from both technical and nontechnical standpoints. This session was recorded at the 2019 O'Reilly Velocity Conference in San Jose.

    Abstract: Systems may be going cloud native, but your CI/CD may not be keeping up. It's challenging to make sure the environments you test and develop on have parity with the environments you deploy to, and you also have to keep track of what you deployed where and when you deployed it. Moving your systems to more complicated environments impacts your entire software supply toolchain. Christie Wilson (Google) explains the challenges of testing, building, and deploying in a cloud native landscape. She examines how tools and systems available today meet these challenges, the benefits you get from cloud native CI/CD, and what's still to be solved. Prerequisite knowledge Experience with CI/CD pipelines and container-based systems What you'll learn Learn what factors to weigh and what your options are when deciding how to use CI/CD in a cloud native landscape This session was recorded at the 2019 O'Reilly Open Source Software conference in Portland.

    Abstract: Organizations are shifting from centralized control and planning to adaptive approaches focusing on time to market, delegated autonomy, and freedom to experiment. In this new world of two-pizza teams organized around microservices, there are two common failure modes: the first is hierarchical command and control from ivory-tower architects with strict lists of approved tools and rigorous control gates for design reviews at various stages; at the opposite end of the spectrum is chaos with every team doing whatever they want and close to zero governance. Jonny LeRoy explores the Goldilocks zone that makes sure organizational risks and opportunities are handled while still giving teams as much autonomy as possible within those constraints. He draws on ThoughtWorks's recent client experience to delve into some of the strategies and approaches for creating the Goldilocks zone of lightweight governance: automating compliance, focusing on vision, principles and constraints, enrolling gatekeepers as collaborators, paved roads and the pit of success, tech radar as a lightweight governance tool, and ADRs for visibility. He also touches on how to help architects become comfortable with evolution, the org design implications, how to be responsive to skill levels on teams, and how to think about innovation zones.

    Abstract: When Healthcare.gov officially launched on October 1, 2013, problems with the website were apparent immediately. High demand caused the site to go down within two hours of launch, and only six people were able to actually complete their applications on the first day. These issues were eventually addressed with the help of Nava, a public benefit corporation formed during efforts to help fix HealthCare.gov's troubled launch. Ultimately, over 1 million people successfully signed up for healthcare by the end of the open enrollment period. In this Spotlight on Learning from Failure , Sha Hwang, cofounder and COO of Nava, shares the stories behind scaling a company whose chief customer was one of the largest organizations on the planet: the United States government. You'll discover organizational, technical, and communication challenges Nava encountered-as well as best practices for building better foundations for culture, diversity, and impact-as you learn how this small team cut through mountains of red tape to transform a highly public debacle into well-oiled (and sustainable) machine. Recorded on August 27, 2019. See the original event page for resources for further learning or watch recordings of other past events . O'Reilly Spotlight explores emerging business and technology topics and ideas through a series of one-hour interactive events. In live conversations, participants share their questions and ideas while hearing the experts' unique perspectives, insights, fears, and predictions for the future. In every edition of Spotlight on Learning from Failure , you'll discover the lessons learned from failures both large and small. You'll discover how successful companies have addressed setbacks, missteps, and challenges and how you can grow from their examples.

    Abstract: Micro-frontends are a new architectural trend in the development of frontend applications. This architectural style can provide tremendous benefits to your projects and organization, offering a level of decoupling never seen before in single-page applications or universal architectures. That said, micro-frontends need to be explored in practice. Luckily there are already a few companies using them at scale. Drawing on his work at DAZN, Luca Mezzalira explains how to implement micro-frontends, enabling you to scale up a project with tens of developers without reducing the throughput. Topics include: Defining a micro-frontend architecture Using this architectural style to become framework agnostic Scaling up teams on a single project without losing throughput Building and deploying a micro-frontend application Analyzing the benefits and drawbacks of this architecture

    Abstract: A RESTful approach to microservices can improve the stability and resilience of services, reduce the need for extensive changes and redeployment when the domain model changes, and greatly increase the flexibility of individual services, including the ability to automatically work with other newly discovered services. Mike Amundsen walks you through building adaptable microservices that take advantage of the features of REST, including statelessness, self-description, and using hypermedia to discover and modify application state. You'll learn how to design services that advertise themselves to the network, discover their own "partner" services, and can adapt to subtle changes to existing services without relying only on recode-and-redeploy patterns for maintaining overall system operation.

    Abstract: As both engineers and managers reach midcareer levels referred to as career or terminal levels (e.g., senior engineer or senior manager levels in many technology companies), they are often faced with uncertainty and ambiguity on possible next steps in their career. Drawing on her experience supporting engineers and managers through career growth in environments ranging from large company environments to startups, Uma Chingunde (Stripe) offers strategies to think about careers at this stage. She addresses some questions such as, How do you think of your career goal outside of the usual career ladders? How do these change as you get more senior? What are traditional versus nontraditional IC and manager paths you can explore? How do you think about the engineer versus manager track? What are some variations on the above for underrepresented groups?

    Abstract: Teams considering adoption of service-based or microservice architectures have a wealth of information to consult on the organization and design of application software, the benefits of these architectural approaches, and general considerations for the prerequisites. Even if you're not ready to adopt a microservices architecture, you still want the benefits of rapidly deployable, highly automated infrastructure that enables rapid delivery of new features and services. What can you do to build an infrastructure that supports such mythical delivery? Delivery infrastructure refers to a set of products and capabilities that serve the needs of product developers and operations teams. Paula Paul and Rosemary Wang offer a deeper look at an approach to building the necessary delivery infrastructure to support a distributed service or microservice architecture. You'll explore delivery infrastructure products and their capabilities as well as related aspects of change friction for core compute, observability, delivery pipelines, security, persistence, and more. This session is sponsored by ThoughtWorks.

    Abstract: The idea that architecture can support change was described by Neal Ford, Rebecca Parsons, and Pat Kua in 2017 as evolutionary architecture. How do we enable this kind of evolution? Architectural goals and constraints change independently of functional expectations. Fitness functions describe how close an architecture is to achieving an objective goal. During test-driven development, we write tests to verify that features conform to desired business outcomes; we can also write fitness functions that measure and monitor a system's alignment to architectural goals as they evolve. In order for technology to deliver lasting business value, it must be adaptable. Prose enterprise architecture standards or rigid architecture frameworks often don't have the flexibility to support constant change. Regardless of application architectures (monolith, microservices, microkernel, etc.) or business architecture, fitness function-driven development can introduce continuous feedback for architectural conformance and inform the development process as it happens rather than after the fact. Architecture can be expressed and tested as code, in a pipeline, in the same way we express and test business capability and infrastructure as code. The concept of architecture as code is a tremendous leap for most traditional architecture and development teams, challenging long-standing perceptions and mindsets. Paula Paul and Cassandra Shum (ThoughtWorks) share adventures in the enterprise as they take architects and engineers on a journey toward fitness function-driven development, with real-world hurdles and unexpected insights, as they rethink the connection between architecture and business value in a digital world.

    Abstract: So you want to test your complex application that involves large-scale distributed systems. But how do you feel about testing it effectively just using your test environment? Today, automated testing of Netflix client and server applications runs at scale in production. Within a few years, the company's testing has gone from a low-volume manual mode to one where it is continuous, voluminous, and fully automated. Collectively, Netflix teams create hundreds of thousands of tester accounts every day, each being used in thousands of test scenarios, to the point where service providers are more wary of getting paged for causing instability to internal testers than for causing an external outage. Vasanth Asokan offers a study of the evolution and anatomy of production testing at scale at Netflix, explaining why there was a desire to test in production, what Netflix did to try to keep testing out of production, and where testing belongs, anyway. Along the way, Vasanth shares a few case studies to demonstrate both the benefits and the less tangible diffused impacts of concentrated, uncoordinated testing against customer-facing infrastructure. Vasanth also looks at other forms of testing, such as load, failure, and simulation testing, and explains the role they play in ensuring a fully functioning customer experience. Join in to learn whether the benefits outweigh the risks of executing untested code in production or whether it's better to focus on creating a production mirror. If you run large-scale distributed systems, this talk will better inform your overall testing strategy, illustrate specific techniques that work at scale, and provide trade-offs to consider.

    Abstract: Software and applications run on a real physical network. Trying to deliver packets across the data center or around the world can pose unique challenges depending on the application and performance requirements because modern networks are a complicated mix of technologies. Understanding the interaction between these components can be challenging when the network and applications are controlled by one administrative entity. It's even more complicated when the underlying resources are leased from an IaaS provider. The complex interplay between the various components can have unwanted effects on applications. Successfully running applications requires you to have some understanding of the various things that may affect performance. André Henry discusses latency and bandwidth, provides a high-level overview of network components and topology, explores software-defined networks (SDNs), shares how various protocols and configuration can affect network performance, and explains buffers and buffer bloat.
