Hadoop/Hbase was designed to crunch a huge amount of data in a batch mode and provide meaningful results to this data. However, as the technology evolved over the years, the original architecture was fine tuned to move from the world of big-iron to the choice of cloud infrastructure:
It provides optimum pricing for the provisioning of new hardware, storage, and monitoring the infrastructure.
One-click setup of additional nodes and storage.
Elastic load-balancing to different clusters within the Hbase ecosystem.
Ability to resize the cluster on-demand.
Share capacity with different time-zones, for example, doing batch jobs in different data centers to and real-time analytics near to the customer.
Easy integration with other Cloud-based services.
HBase on Amazon EMR provides the ability to back up your HBase data directly to Amazon Simple Storage Service (Amazon S3). You can also restore from a previously created backup when launching an HBase cluster.
