OpenSearch Service (formerly Elasticsearch Service) is a managed service for search and log analytics. It’s the go-to for full-text search, log exploration, and real-time application monitoring dashboards.
Where it fits
The tell is “search across large text/log data” or “analyze and visualize logs in near real time” (often paired with Kinesis Firehose feeding it, and Kibana/OpenSearch Dashboards for visualization). It’s for search and log analytics, distinct from Redshift (BI warehouse) and Athena (ad-hoc S3 SQL).
