Part II. Practices
Building upon the solid foundation of SRE principles covered in Part I, Part II dives deep into how to conduct SRE-related activities that Google has found important for operating at scale.
Some of these topics, such as data processing pipelines and managing load, won’t apply to all organizations. Other topics, such as safely handling changes with configuration and canarying, on-call practices, and what to do when things go wrong, contain valuable lessons for any SRE team.
This part also introduces an important SRE skill—Non-Abstract Large System Design (NALSD)—and presents a detailed example of how to practice this design process.
As we move from SRE foundations to practices, we wanted to provide a bit more context on the relationship between operational duties and project work, and the engineering it takes to accomplish both strategically.
