Google SRE

Site Reliability Engineering (SRE) is a discipline that incorporates aspects of software engineering and applies them to infrastructure and operations problems. The goal is to create scalable and highly reliable software systems.

🔹 Core Principles

  • Embrace Risk: Error budgets, Service Level Objectives (SLOs)

  • Service Level Management: SLOs, SLIs, SLAs

  • Eliminate Toil: Automate repetitive tasks

  • Monitoring & Alerting

  • Release Engineering & CI/CD

  • Incident Management & Postmortems

  • Capacity Planning & Scaling

  • Production Readiness Reviews
