Amazon EMR provides a hosted Hadoop, Pig, Hive, and HBase services for developers and businesses to help them build Big Data applications without worrying about the deployment complexity or managing Hadoop clusters with underlying infrastructure. Many improvements have been made into the open source Apache Hadoop and other applications in order to make them interact seamlessly with other AWS services.
Let's now discuss some of the key features of EMR, most of which come with EMR being a service provided over cloud infrastructure. These are the features that are hard to achieve on an in-house local cluster:
