Introduction

Majority of data is stored on local networks with servers that may be clustered and sharing
storage. This approach has developed into a stable architecture, and provides decent redundancy
when arranged right. Cloud computing, a relatively new technology demands attention as it is
fast changing the direction of the technological scenario.
Be it Amazon’s robust Amazon S3 cloud storage model or Google’s unique and scalable Google
File System, it is clear that cloud computing has arrived with much to be picked up from.
