CLOUD COMPUTING UTILISATION

            There are four main actors to speak in cloud computing: the cloud provider, the software service provider, customer and the user.Each of them represents centres of computer-related activity that can overlap to some degree.The service provider owns the the infrastructure, hardware, software, and the network facilitiesneeded to supply cloud computing managed by the operating system.CSP performs as function that can be used to run computer programs and is known as cloud platform (CP).Cloud platform provides service to applications in the same way that "software as a service" programs provide to their client using the cloud as a media.Cloud Platform is much more about operating.The SSP is an independent software that develops software package as delivering vehicle for computing and provides applications to the customwers.The customer (C) is comprised of of several employees that use the application and are regarded as users.The user (U) is a person that uses cloudcomputing service via a web browser.the user can either be an employee of an organisation that is contracted to use SaaS provided by an ISV or acquired independently to run in the cloud.

For example, we will  be using CSP-CP-ISV-C-U if  our company has acquired an operational package from a software vendor and is hosting that software in the cloud.Similarly, we will be using CSP-CP-U if we are using an office package provided by CSP and  accessed via browser.

Concluding, this form of conceptualization is important from a privacy point of view, because each exchange between modules represents a touch point for privacy concerns.
