Google Cloud for DevOps Engineers

Overview of this book

DevOps is a set of practices that help remove barriers between developers and system administrators, and is implemented by Google through site reliability engineering (SRE). With the help of this book, you'll explore the evolution of DevOps and SRE, before delving into SRE technical practices such as SLA, SLO, SLI, and error budgets that are critical to building reliable software faster and balance new feature deployment with system reliability. You'll then explore SRE cultural practices such as incident management and being on-call, and learn the building blocks to form SRE teams. The second part of the book focuses on Google Cloud services to implement DevOps via continuous integration and continuous delivery (CI/CD). You'll learn how to add source code via Cloud Source Repositories, build code to create deployment artifacts via Cloud Build, and push it to Container Registry. Moving on, you'll understand the need for container orchestration via Kubernetes, comprehend Kubernetes essentials, apply via Google Kubernetes Engine (GKE), and secure the GKE cluster. Finally, you'll explore Cloud Operations to monitor, alert, debug, trace, and profile deployed applications. By the end of this SRE book, you'll be well-versed with the key concepts necessary for gaining Professional Cloud DevOps Engineer certification with the help of mock tests.

Psychological safety

One of the key pillars of SRE is to accept failure as normal. This implies that failures are imminent, but the key is to learn from the failures and ensure that the same mistake is not repeated the next time. As a result, SRE promotes open communication within teams and between members of the team and its leaders to ensure that a failure is evaluated objectively from a process standpoint and not from an individual standpoint. The core idea is to provide a sense of psychological safety, which is extremely important to implement the practice of Blameless Postmortems.

SRE defines psychological safety as the belief that a manager or an individual contributor will not be singled out, humiliated, ridiculed or punished for the following:

  • Committing a mistake that could result in a potential incident or a problem
  • Bringing up a concern related to a decision with respect to design, implementation, or process that could later have adverse impacts
  • Asking...
