Becoming a Rockstar SRE

By: Jeremy Proffitt, Rod Anami

Overview of this book

Site reliability engineering is all about continuous improvement, finding the balance between business and product demands while working within technological limitations to drive higher revenue. But quantifying and understanding reliability, handling resources, and meeting developer requirements can sometimes be overwhelming. With a focus on reliability from an infrastructure and coding perspective, Becoming a Rockstar SRE brings forth the site reliability engineer (SRE) persona using real-world examples. This book will acquaint you the role of an SRE, followed by the why and how of site reliability engineering. It walks you through the jobs of an SRE, from the automation of CI/CD pipelines and reducing toil to reliability best practices. You’ll learn what creates bad code and how to circumvent it with reliable design and patterns. The book also guides you through interacting and negotiating with businesses and vendors on various technical matters and exploring observability, outages, and why and how to craft an excellent runbook. Finally, you’ll learn how to elevate your site reliability engineering career, including certifications and interview tips and questions. By the end of this book, you’ll be able to identify and measure reliability, reduce downtime, troubleshoot outages, and enhance productivity to become a true rockstar SRE!

Chaos Injector – Advanced Systems Stability

Nothing can survive for long without evolving. Site reliability engineers (SREs) are in an endless cycle of learning and applying as they become proficient in making systems resilient to incidents, downtimes, and outages. When systems are stable enough, SREs understand how to increase system trustworthiness by injecting chaos into it and checking weak links.

Two of the most unique and notorious practices inside the site reliability engineering domain are the wheel-of-misfortune game and chaos engineering; they can bring any system’s reliability to a new level. This chapter starts by explaining these two techniques and how they work towards increasing a system’s availability, resiliency, and reliability. Then this chapter conveniently demonstrates how to apply such methods by using examples and exercises around the topic.

In this chapter, we’re going to cover the following main topics:
