Observability in Serverless Application
summary
Shows how to instrument a serverless feedback app (API Gateway, Lambda, DynamoDB, S3) and tie logs metrics and traces together using CloudWatch and X‑Ray, with ServiceLens for a single-pane view. Demonstrates concrete APIs and tools: PutMetricData, embedded metric format, Lambda layers for the AWS Distro for OpenTelemetry, and CloudWatch Logs Insights queries. Gives scale numbers—1 quadrillion+ metrics per month, 3.9 trillion events, 100 PB logs—and describes managed alternatives (Prometheus, OpenSearch, Grafana) and when each actually helps pinpoint latency, errors, or root cause.
