Cloud MapReduce is developed at Accenture Technology Labs. It is a MapReduce implementation on top of the Amazon cloud Operating System(OS). By exploiting a cloud OS's scalability, Cloud MapReduce achieves three primary advantages over other MapReduce implementations built on a traditional OS:
- It is faster than other implementations (e.g., 60 times faster than Hadoop in one case).
- It is more scalable because it has no single point of bottleneck.
- It is dramatically simpler with only 3,000 lines of code (e.g., two orders of magnitude simpler than Hadoop).
