Amazon Elastic MapReduce, or EMR, is a cloud big data platform for processing massive amounts of data using open source tools such as Apache Spark, Apache Hive, Apache HBase, Apache Flink, Apache Hudi, and Presto.

Machine learning

EMR's built-in machine learning tools include Apache Spark MLlib, TensorFlow, and Apache MXNet. The tools can be used for building scalable machine learning algorithms and predictive analytics.

Extract, transform, load (ETL)

EMR can be used to perform data transformation workloads (ETL) such as sort, aggregate, and join on large datasets.
