Another difference is that Cloud Mapreduce doesn't scale well when there are
a large number of values for the same key. They collect in a single SQS
queue per partition, and in the reducer reads that into a hashtable that
never spills to disk. So, if you have more values for a key than fit in RAM,

the confusion to me is If cloudMapReduce just is focused on Cloud
Computing Infrastructure and must be depend on overall distributed
