DevOps

Does technology actually matter? And how can we apply technology to drive business value?

For years, we’ve been told that the performance of software delivery teams doesn’t matter—that it can’t provide a competitive advantage to our companies. Through four years of groundbreaking research, Dr. Nicole Forsgren, Jez Humble, and Gene Kim set out to find a way to measure software delivery performance—and what drives it—using rigorous statistical methods. This book presents both the findings and the science behind that research.

Readers will discover how to measure the performance of their teams, and what capabilities they should invest in to drive higher performance.

GitOps follows the practices of infrastructure as code (IaC), allowing developers to use their day-to-day tools and practices such as source control and pull requests to manage apps. With this book, you'll understand how to apply GitOps bootstrap clusters in a repeatable manner, build CD pipelines for cloud-native apps running on Kubernetes, and minimize the failure of deployments.

You'll start by installing Argo CD in a cluster, setting up user access using single sign-on, performing declarative configuration changes, and enabling observability and disaster recovery. Once you have a production-ready setup of Argo CD, you'll explore how CD pipelines can be built using the pull method, how that increases security, and how the reconciliation process occurs when multi-cluster scenarios are involved. Next, you'll go through the common troubleshooting scenarios, from installation to day-to-day operations, and learn how performance can be improved. Later, you'll explore the tools that can be used to parse the YAML you write for deploying apps. You can then check if it is valid for new versions of Kubernetes, verify if it has any security or compliance misconfigurations, and that it follows the best practices for cloud-native apps running on Kubernetes.

By the end of this book, you'll be able to build a real-world CD pipeline using Argo CD.

What you will learn

• Understand GitOps principles and how they relate to IaC
• Discover how Argo CD lays the foundation for reconciling Git state with the cluster state
• Run Argo CD in production with an emphasis on reliability and troubleshooting
• Bootstrap Kubernetes clusters with essential utilities following the GitOps approach
• Set up a CD pipeline and minimize the failure of deployments
• Explore ways to verify and validate the YAML you put together when working with Kubernetes

Getting software released to users is often a painful, risky, and time-consuming process.

This groundbreaking new book sets out the principles and technical practices that enable rapid, incremental delivery of high quality, valuable new functionality to users. Through automation of the build, deployment, and testing process, and improved collaboration between developers, testers, and operations, delivery teams can get changes released in a matter of hours—sometimes even minutes–no matter what the size of a project or the complexity of its code base.

Jez Humble and David Farley begin by presenting the foundations of a rapid, reliable, low-risk delivery process. Next, they introduce the “deployment pipeline,” an automated process for managing all changes, from check-in to release. Finally, they discuss the “ecosystem” needed to support continuous delivery, from infrastructure, data and configuration management to governance.

The authors introduce state-of-the-art techniques, including automated infrastructure management and data migration, and the use of virtualization. For each, they review key issues, identify best practices, and demonstrate how to mitigate risks. Coverage includes

• Automating all facets of building, integrating, testing, and deploying software
• Implementing deployment pipelines at team and organizational levels
• Improving collaboration between developers, testers, and operations
• Developing features incrementally on large and distributed teams
• Implementing an effective configuration management strategy
• Automating acceptance testing, from analysis to implementation
• Testing capacity and other non-functional requirements
• Implementing continuous deployment and zero-downtime releases
• Managing infrastructure, data, components and dependencies
• Navigating risk management, compliance, and auditing

Whether you’re a developer, systems administrator, tester, or manager, this book will help your organization move from idea to release faster than ever—so you can deliver value to your business rapidly and reliably.

Use continuous Integration (CI) and continuous delivery (CD) to improve the speed of software delivery. This book presents a game changer—how to use pipelines to automate the software delivery process. The theories about CI/CD are much the same, but the book covers what the development of pipelines looks like and how testing of pipelines themselves should be performed.

Most teams just plunge into coding, without thinking about the CI/CD process itself. Why don’t we use the same development method for pipelines that we use for apps?

Pipelines code development undergoes similar stages as application code development, such as requirements analysis, development, testing, implementation, operations, and monitoring. This is the starting point of the book. It describes the current challenges with pipeline development and how this process can be improved and structured. It describes in detail how to design pipelines and shows examples in BPMN 2.0 notation.

What You’ll Learn

• Know the shortcomings and challenges of current pipeline development such as misalignment between the pipeline engineer and the team’s workflow, the use of infrastructure as code (IaC), and pipeline security
• Understand the need for CI/CD requirements through the book's non-exhaustive list of more than 60 CI/CD requirements provided to inspire and increase awareness
• See how certain choices affect the way a pipeline is designed (and realized)
• Become familiar with branching strategy, build strategy, test strategy, release strategy, and deployment strategy that are explained in detail in the book, including their effect on pipeline design
• Know how pipelines can be unit tested, using a real-world example
• Know how performance bottlenecks in a pipeline occur, how they can be detected, and how they can be solved
• View a complete implementation, including code, showing how the guidelines in this book are applied to a real use case
