Cloud storage is actually made up of many distributed resources, but still acts as one. It is highly fault tolerant through redundancy and distribution of data also it is highly durable through the creation of versioned copies. Users can remotely store their data into the cloud so as to enjoy the on-demand high quality applications and services from a shared pool of configurable computing resources. Data integrity is a prime concern in cloud computing as users no longer have physical possession of the outsourced data.
