Amazon Elastic MapReduce enables customers to easily and cost-effectively process vast amounts of data utilizing a hosted Hadoop framework running on Amazon's web-scale infrastructure. It was launched in 2009 and allows customers to spin up large or small Hadoop job flows in minutes without having to manage compute clusters or tune Hadoop themselves. The service provides a reliable, fault tolerant and cost effective way for customers to solve problems like data mining, genome analysis, financial simulation and web indexing using their existing Hadoop applications.
