Data Processing Services
Transforming data at scale.
| Service | Job | Choose when | Key distinction |
|---|---|---|---|
| AWS Glue | Serverless ETL | Prepare data for analytics, discover schema | No infrastructure; opinionated |
| Amazon EMR | Managed Hadoop/Spark | Specific frameworks/versions, fine tuning | You manage the cluster; full control |
- Glue (serverless, minimal config) vs EMR (cluster control, open-source frameworks). Both process at scale.
