SLIs, SLOs, and SLAs Explained for Engineers

Day 2 of the 60-day Production Engineering challenge. We break down Service Level Indicators, Objectives, and Agreements -- what they are, how they relate, and the mistakes teams make when setting them up. Topics covered: - SLI formula and implementation - Choosing SLI types (availability, latency, throughput, correctness) - Setting SLO targets based on observed data - Error budget math - SLA structure and financial penalties - Common mistakes to avoid #SRE #ProductionEngineering #DevOps #Reliability #SLO #SLA
