The overwhelming majority of a software systemâ??s lifespan is spent in use, not in design or implementation. So, why does conventional wisdom insist that software engineers focus primarily on the design and development of large-scale computing systems?

In this collection of essays and articles, key members of Googleâ??s Site Reliability Team explain how and why their commitment to the entire lifecycle has enabled the company to successfully build, deploy, monitor, and maintain some of the largest software systems in the world. Youâ??ll learn the principles and practices that enable Google engineers to make systems more scalable, reliable, and efficientâ??lessons directly applicable to your organization.

This book is divided into four sections:

• Introductionâ??Learn what site reliability engineering is and why it differs from conventional IT industry practices
• Principlesâ??Examine the patterns, behaviors, and areas of concern that influence the work of a site reliability engineer (SRE)
• Practicesâ??Understand the theory and practice of an SREâ??s day-to-day work: building and operating large distributed computing systems
• Managementâ??Explore Google's best practices for training, communication, and meetings that your organization can use

Can a system be considered truly reliable if it isn't fundamentally secure? Or can it be considered secure if it's unreliable? Security is crucial to the design and operation of scalable systems in production, as it plays an important part in product quality, performance, and availability. In this book, experts from Google share best practices to help your organization design scalable and reliable systems that are fundamentally secure.

Two previous O’Reilly books from Google—Site Reliability Engineering and The Site Reliability Workbook—demonstrated how and why a commitment to the entire service lifecycle enables organizations to successfully build, deploy, monitor, and maintain software systems. In this latest guide, the authors offer insights into system design, implementation, and maintenance from practitioners who specialize in security and reliability. They also discuss how building and adopting their recommended best practices requires a culture that’s supportive of such change.

You’ll learn about secure and reliable systems through:

• Design strategies
• Recommendations for coding, testing, and debugging practices
• Strategies to prepare for, respond to, and recover from incidents
• Cultural best practices that help teams across your organization collaborate effectively

In 2016, Googleâ??s Site Reliability Engineering book ignited an industry discussion on what it means to run production services todayâ??and why reliability considerations are fundamental to service design. Now, Google engineers who worked on that bestseller introduce The Site Reliability Workbook, a hands-on companion that uses concrete examples to show you how to put SRE principles and practices to work in your environment.

This new workbook not only combines practical examples from Googleâ??s experiences, but also provides case studies from Googleâ??s Cloud Platform customers who underwent this journey. Evernote, The Home Depot, The New York Times, and other companies outline hard-won experiences of what worked for them and what didnâ??t.

Dive into this workbook and learn how to flesh out your own SRE practice, no matter what size your company is.

Youâ??ll learn:

• How to run reliable services in environments you donâ??t completely controlâ??like cloud
• Practical applications of how to create, monitor, and run your services via Service Level Objectives
• How to convert existing ops teams to SREâ??including how to dig out of operational overload
• Methods for starting SRE from either greenfield or brownfield
