Platform Engineering

Consolidates Observability and Performance Engineering to build high-performance, resilient, and observable systems.

When to Use This Skill

• Observability: Setting up Prometheus/Grafana, OpenTelemetry, logging pipelines.
• Performance: Debugging latency, optimizing DB queries, caching strategies.
• Reliability: Defining SLIs/SLOs, Load Testing, Chaos Engineering.
• Infrastructure: Incident response and post-mortems.

Core Disciplines

1. Observability (The "Three Pillars")

Logs (Events)

• Purpose: Debugging specific events. "What happened?"
• Best Practice: Structured JSON logging. Application-context only (no noise).
