A Review On Cloud Storage Architectures

Cloud Computing has recognized as the next-generation architecture of IT companies. Cloud computing provides elastic, scalable, reliable services for individuals as well as organizations. In the cloud computing, everything is considered as the service and the service provided by Cloud is dynamic, diverse, and context-related. cloud computing moves the application software and databases to the centralized large data centers, where the management of the data and services may not be fully trustworthy. Storage services based on public clouds which provide customers with scalable and dynamic storage. By moving their data to the cloud customers can avoid the costs of building and maintaining a private storage infrastructure, opting instead to pay a service provider as a function of its needs. For most customers, this provides several benefits including availability (i.e., being able to access data from anywhere) reliability (i.e., not having to worry about backups) and confidentiality (i.e., accessed only by authorized parties) at a relatively low cost.
