Summary

Alright! We made it through the introduction. We learned what SRE is at a high level, and we talked about the sorts of problems people in the role tend to focus on. We discussed the structure of the book, and also how to apply that structure to a software project.

In the next chapter, we will be diving into the world of monitoring! Monitoring is the foundation of learning about a system. It is how you record historical data about a system and learn about what is actually going on by analyzing the data you collect. By the end of the chapter, you'll know the basics of instrumenting an application, aggregating that data, storing that data, and displaying it.
