So what is it exactly?
It is a networked online storage where data is stored in virtualized pools of storage which are generally hosted by third parties. Physically, the data may span across multiple servers. Information stored with these providers is accessible via the internet or Wide Area Network (WAN). It’s cheap, doesn’t require installation (if you are using web link, otherwise you can install setup), doesn’t need replacing, has backup and recovery systems, has no physical presence, requires no environmental conditions, requires no personnel and doesn’t require energy for power or cooling.
On the other hand, availability of cloud data storage is a serious issue. Cloud data storage relies on network connectivity between the LAN and the cloud data storage provider. And, when data is distributed it is stored at more locations increasing the risk of unauthorized physical access to the data. For example, in cloud based architecture, data is replicated and moved frequently so the risk of unauthorized data recovery increases dramatically. (e.g. disposal of old equipment, reuse of drives, reallocation of storage space).
