From Journey to Practice: SRE and Reliability Engineering

RELIABILITY IS MEASURED. From the first alert to the blameless postmortem.

A six-hour incident on Black Friday, and not a single alert fired. That episode is what makes Right Route, the fictional company in this course book, take reliability seriously.

In 10 chapters, you go from "the system is up" to a service with reliability targets, alerts worth getting, an organized incident response and real learning afterward.

You will learn to: define SLIs, SLOs and error budgets from the customer's experience; build observability and diagnose problems layer by layer; replace noisy alerts with actionable ones, including burn-rate alerts; run incidents and write blameless postmortems; plan capacity, test resilience and automate toil.

4 case studies, 20 diagrams, more than 30 labs (two on AWS, with cost alerts and cleanup, and four in Python on your own machine), checklists and exercises with an answer key.
