Google Cloud for DevOps Engineers

By: Sandeep Madamanchi

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.

Section 1: Site Reliability Engineering – A Prescriptive Way to Implement DevOps

The core focus of this section is Site Reliability Engineering (SRE). The section starts with the evolution of DevOps and its life cycle and introduces SRE as a prescriptive way to implement DevOps. The emphasis is on defining the reliability of a service and ways to measure it. In this section, SRE technical practices such as Service-Level Agreement (SLA), Service-Level Objective (SLO), Service-Level Indicator (SLI), error budget, and eliminating toil are introduced and are further elaborated. Fundamentals and critical concepts around monitoring, alerting, and time series are also explored to track SRE technical practices. However, SRE technical practices cannot be implemented within an organization without bringing cultural change. Google prescribes a set of SRE cultural practices such as incident management, being on call, psychological safety, and the need to foster collaboration. This section...
