Centralized Amazon ECS task logging with Amazon OpenSearch

Amazon ECS tasks fire logs through a FireLens sidecar.
Fluent Bit ships them into a shared Amazon OpenSearch Serverless domain.
Cross-account IAM roles lock down access.
The pipeline centralizes logs, unlocks full-text search, SQL and PPL queries, and slashes storage costs with on-demand indexing.

Trend to watch: Serverless OpenSearch is elbowing CloudWatch aside. Expect richer log forensics and tighter cost control across container fleets.
