Elastic MapReduce (EMR)was introduced by Amazon in April 2009. Provisioning of the Hadoop cluster, running and terminating jobs, and handling data transfer between EC2 and S3 are automated by Elastic MapReduce. Apache Hive, which is built on top of Hadoop for providing data warehouse services, is also offered in Elastic MapReduce.

In June 2012, premium options for EMR were added that replace ordinary Hadoop with MapR's M3 and M5 versions. These options provide additional capabilities over and above what the default EMR offering provides.
