ok, it's not bingo, but it is a crossword
Here are some slides I've presented at a number of places people have asked me to post.
Lastly i'd like to add that "Self Correcting Systems" are vital to the success of SRE. Of course we all hear about auto-remediation or self-healing technologies. While those are self evident I personally recommend you think about your people and processes. Think about the motivations, rewards and expected human behaviors. If you focus on a target of reducing false monitoring alarms, someone MIGHT decide to just disable the alarms instead of fixing them. If you focus on auto-healing too much, you may miss the fact that most things that can/should be fixed by auto-healing is a design flaw/problem. Unfortunately we tend to ask how many fires we put out, not how many fires we prevented because "fires put out" is easier to count. We have to educate our stakeholders and leadership to learn that an ounce of prevention is worth a pound of cure!
SRE is an abbreviation for Service Reliability Engineering, also known as Site Reliability Engineering. SRE can also be a job description for a Service(or Site) Reliability Engineer. DevOps is a methodology (and should never be someones title) where a developer supports the code they write in production.
Service Reliability Engineering exists to improve reliability of services by writing software to keep a service functioning properly and to drive the improvement through feedback primarily around reliability, availability, observability & serviceability. SREs are also expected to do a significant amount of troubleshooting to find the root cause of an issue and not focus on the symptoms. SRE's often help Developers with Infrastructure, Deployment, Configuration, Monitoring & Metrics to make their software easy to update, manage and monitor.
SRE is a set of practices, metrics, and prescriptive ways to ensure reliability and uniformity to enable success at scale.
SRE is often a Gate to Production (grant access, make/approve/authorize production changes)
