Cloud computing is a way for providing information technology (IT) services where resources are taken from the Internet through web-based tools applications and opposed to a direct connection to a server. Cloud is not a particular product, but it is the way of delivering IT services that are consumable on demand, elastic to scale up and down as needed, and follow a pay-for-usage model. Out of the three common types of cloud computing models where Infrastructure as a Service (IaaS) is the service model that provides servers, computing power, network bandwidth and Storage capacity, as a service to their subscribers. Cloud can be relate to many things but without the basic storage pieces, which is provided the service namely Cloud Storage, none of the other applications is possible . This paper measure Cloud Storage, which covers the basic technologies in cloud computing and Cloud Storage, management insight tell about cloud computing, and driving forces of cloud computing and cloud storage,.The advantages and challenges of cloud storage and concludes by highlighting few challenges to be addressed by the cloud storage providers. Cloud computing is idea of taking all the heavy lifting involved in searching and processing data away from the device (computer and lap top) you carry around, or sit and work at, and moving that work to huge computer clusters far away in cyberspace.
