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

2. 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.
