Site Reliability Engineering: How Google Runs Production Systems

by Betsy Beyer

Choose just enough SLOs to provide good coverage of your system’s attributes. Defend the SLOs you pick: if you can’t ever win a conversation about priorities by quoting a particular SLO, it’s probably not worth having that SLO.

You can’t “fix” people, but you can fix systems and processes to better support people making the right choices when designing and maintaining complex systems.

When implementing release tests, the fake backend is often maintained by the peer service’s engineering team and merely referenced as a build dependency.

If you take away just one lesson from this chapter, remember that you only know that you can recover your recent state if you actually do so.

Make sure that you jitter automatic requests.
