1. Amazon EMR
Amazon Elastic MapReduce (Amazon EMR), it distributes the computational work across clusters of virtual servers running in the Amazon cloud using Hadoop
- It users a distributed processing architecture called MapReduce in which a task is mapped to a set of servers for processing.
- The results of the computation performed by those servers is then reduced down to a single output set.
- One node, designated as the master node, controls the distribution of tasks.
