Site Reliability Engineering from Google - what happens when you ask a software engineer to design an operations team. Not traditional ops or DevOps - applying software engineering to infrastructure.
Google runs services for billions (Search, Gmail, YouTube, Maps) with 99.99%+ uptime. These practices made that possible.
100% uptime is the wrong target. Use error budgets to balance reliability vs velocity.
Define and measure service quality with SLIs, SLOs, SLAs.
Automate manual, repetitive work. Target <50% time on toil.
Alert on symptoms (user-facing), not causes. Use golden signals.
Blameless postmortems, clear escalation, reduce MTTR.
Plan for growth, forecast demand, optimize resource usage.
SRE practices power:
