Benefits of EMR
AWS EMR supports the whole technology stack, which is inclusive of Apache Spark, HBase, Hive, Flink Presto, Ganglia, Pig, MXNet and Sqoop. It significantly improves the setup of clusters as this bundle of packages is automatically installed during the cluster creation. Along with these, Amazon’s EMR demonstrates several other benefits that include:
Reduced efforts
EMR automatically takes care of node provision, its infrastructural setup, Hadoop configuration, or cluster tuning.
Optimal & transparent costs
Pricing of EMR is entirely predictable and straightforward: Users need to pay-per-instance rate for every second used.
Auto scaling
Provides thousands of compute resources to process the source data of any scale.
Reliable security
Amazon EMR includes security features that allow only necessary network traffic to the instances using EC2 firewalls.
