In one sentence
A managed search and analytics service for full-text search, log analytics, and near-real-time observability queries.
Key points
- It fits application search, log exploration, metrics analysis, and visualization.
- It commonly receives data from CloudWatch, Kinesis, or Data Firehose.
- It is neither a relational database nor a data warehouse for sustained complex BI.
Exam focus
- Full-text search, log search, and near-real-time analytics point to OpenSearch.
Common pitfalls
- Do not choose by product name alone; confirm data type, latency, control, operations, and cost constraints.
Remember
OpenSearch for search and logs; Redshift for the warehouse.
