11.3 Understanding Cloud Storage

Cloud storage is defined as a model of networked enterprise storage where data is stored not
only in the user’s computer, but in virtualized pools of storage which are generally hosted by
third parties, too. Companies which are hosting operate large data centres, and people who
require their data to be hosted buy or lease storage capacity from them. The data center operators,
in the background, virtualize the resources according to the requirements of the customer and
expose them as storage pools, which the customers can themselves use to store files or data
objects. Physically, the resource may span across multiple servers. The safety of the files depends
upon the hosting websites.

11.3.1 Why Use Cloud Storage?

1. The number of people with access to the data who could be compromised (i.e. bribed, or
coerced) increases dramatically. A single company might have a small team of
administrators, network engineers and technicians, but a cloud storage company will
have many customers and thousands of servers and therefore a much larger team of
technical staff with physical and electronic access to almost all of the data at the entire
facility or perhaps the entire company. Encryption keys that are kept by the service user,
as opposed to the service provider limit the access to data by service provider employees.

2. When data is distributed it is stored at more locations increasing the risk of unauthorised
physical access to the data.
