Site Reliability Engineering

SRE is what happens when you treat operations as a software problem. This path covers SLIs, SLOs and error budgets, observability that answers questions instead of producing dashboards, incident command, and the resilience patterns — timeouts, circuit breakers, backpressure, graceful degradation — that decide whether a bad afternoon becomes an outage.
