The Site Reliability Workbook

The (now former) Google approach to Site Reliability Engineering offers valuable insights, but it shouldn’t be applied blindly. Some sections introduce unnecessary complexity or operational overhead that may not suit every organization or team. However, the foundational principles—especially those related to alerting, SLOs, and error budgets—are robust and widely applicable.
If you’re responsible for running a system and want a solid framework for observability and reliability, this is definitely worth your time.
