Live Coding on Observability for Serverless

" summary

Deploys a sample order app (3 Lambdas, API Gateway, SQS, DynamoDB) with AWS SAM then shows live instrumentation: logs emit CloudWatch Embedded Metrics JSON via Node/Python libs to auto-create business metrics, CloudWatch anomaly detection using 14‑day models and 2–3 standard deviations, composite alarms combining multiple alerts, Logs Insights queries to find cold starts and overprovisioned memory, and X‑Ray tracing with ~5% sampling plus CloudWatch ServiceLens linking traces to logs and metrics. Demo runs end‑to‑end and the canary checks via CloudWatch Synthetics pass.
