Site Reliability Engineering
In plain terms
Applying engineering practices to operations and reliability.
Going deeper
SRE uses software engineering to run reliable, scalable systems, balancing feature velocity with stability via SLOs and error budgets. It originated at Google.
Under the hood
Error budgets quantify acceptable unreliability; automation reduces toil and on-call burden.
Examples
SLOs/error budgets, automation, incident response, on-call, Google SRE.
Think of it like...
Like treating keeping the lights on as a rigorous engineering discipline, not just firefighting.
