Observability for Serverless

on YouTube ↗43m

" summary

Shows how a SAM template wires API Gateway + CloudWatch + a Python Lambda layer into a working observability stack that captures structured JSON logs, metrics and traces, and surfaces cold starts via init_duration. Uses AWS Lambda Powertools with three decorator lines to emit metrics, traces and logs, enables X-Ray and Lambda Insights, and adds a correlation_id in requests. Live demo shows traces ranging 16–28 ms (one >1 s) and the trace IDs tying requests to backend calls.
