Amazon EMR
Managed cluster platform for big-data frameworks — Apache Spark, Hive, Presto/Trino — for large-scale batch processing and ETL. EMR is managed open source under the hood, so the "alternative" is simply self-hosting Apache Spark (most used) or Apache Hadoop on your own cluster (on-prem or any cloud VMs), trading EMR's autoscaling/patching/spot-fleet integration for full control and lower per-hour cost at steady scale.
