observability

CloudWatch Logs Insights bills $0.005 per GB scanned and high-cardinality custom metrics multiply costs. Cardinality budgets, sampling rules, and FinOps fixes.

The AWS observability team built a chaos engineering game on top of the official OTel Demo. 44 injected failures. Three signals. One LLM judge. Here's everything inside it.

Real AWS DevOps practices from production: GitOps on EKS, OpenTelemetry, supply chain security, chaos engineering with FIS, and AI-assisted DevOps with Amazon Q.

Observability is not free, and the industry has collectively underpriced it. CloudWatch log ingestion, metrics explosion, and X-Ray trace volume can together exceed your compute bill — especially once AI workloads introduce high-cardinality telemetry at scale.

A 500ms latency spike in a distributed system could be a slow RDS query, a Lambda cold start, a downstream API timeout, or a CloudWatch Logs ingestion delay. Finding the cause requires correlated logs, traces, and metrics — not grep.

CloudWatch is the most underused service on every AWS bill — and the most overspent on the ones that take it seriously. Logs, metrics, and alarm patterns that catch real outages without burying you in noise (or in the bill).
