Cloud Computing: A Full Guide

Cloud Computing is the use of multiple server computers via a digital network as if they were one. The 'Cloud' itself is a virtualisation of resources (networks, servers, applications, data storage and services) allowing on-demand access for the end user. These resources can be provided with minimal management or service provider interaction.

Cloud Computing offers resources for the end user without the need for technical knowledge of the systems which deliver them. Additionally, the Cloud can provide users with a far greater range of applications, and businesses with scalable and tailored services.

Cloud Computing has many benefits, but there are also some risks associated with it. Global State of Information Security Survey (2014) found that only 18 % of respondents had a policy governing Cloud services. A lack of policies for cloud computing represents a serious security gap for businesses. And since users do not physically possess storage of their own data, that leaves the responsibility and control of data storage with the provider.

Cloud Computing has brought together a range of technologies that can deliver scalable, tailored and virtualised IT resources and applications over the Internet. There are three main types of Cloud Computing:

 

• Software as a service (Saas)

• Platform as a service (PaaS)

• Infrastructure as a service (IaaS)

 

Also, there are several differences between traditional hosting and Cloud hosting:

• Cloud Computing is sold on demands.

• The service is managed by the provider.

• Users can determine the amount of service they require.

• Users can log on to the network from any computer in the world.
