Amazon Athena
- serverless querying service
- ad-hoc queries on data in S3 - pay only data consumed
- schema-on-read - provide table-like translation, where original data in S3 remains unchanged
- no infrastructure itself, just a translation service without loading/ transformation
- **querying logs (**AWS logs/ glue data catalog/ web server logs)
- Athena federated query…other data sources as well that is not S3
security:
- IAM policies
- at rest: data is S3 (inherent S3 encryption)
- in transit: using TLS between Athena and S3 and JDBC
- fine grained access using the AWS glue catalog
