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
