Amazon EMR
Amazon EMR helps you analyze and process vast amounts of data by distributing the computational work across a cluster of virtual servers running in the Amazon Cloud. The cluster is managed using an open-source framework called Hadoop. Amazon EMR lets you focus on crunching or analyzing your data without having to worry about time-consuming setup, management, and tuning of Hadoop clusters or the compute capacity they rely on.
