Cloud computing is a new computing paradigm that attracted many computer users, business, and government agencies. Cloud computing brought a lot of advantages especially in ubiquitous services where everybody can access computer services through internet. With cloud computing, there is no need of physical hardware or servers that will support the company's computer system, internet services and networks. One of the core services provided by cloud computing is data storage. In the past decades, data storage has been recognized as one of the main concerns of information technology. The benefits of network-based applications have led to the transition from server-attached storage to distributed storage.
