Log Analytics (The "Observability") using AWS services

Short summary

A step-by-step guide for building a log analytics pipeline on AWS: ECS containers send logs to CloudWatch, a producer Lambda forwards them to SQS, and a consumer Lambda writes them to OpenSearch for searchability. The key gotcha is decompressing CloudWatch data in the first Lambda before sending to SQS. Includes a checklist for setting up the full pipeline.

• •Pipeline: ECS → CloudWatch → Lambda 1 → SQS → Lambda 2 → OpenSearch
• •SQS acts as a buffer between producer and consumer Lambdas
• •Critical step: decompress CloudWatch data in Lambda 1 before forwarding to SQS
