Cloud Computing is Internet-based computing, whereby shared resources, software and information are provided to computers and other devices on-demand. Cloud Computing is a general term for anything that involves delivering hosted services over the Internet.

A cloud service has three distinct characteristics that differentiate it from traditional hosting:

  • It is sold on-demand, typically by the minute or the hour;
  • it is elastic : a user can have as much or as little of a service as they want at any given time; and
  • The service is fully managed by the provider (the consumer needs nothing but a personal computer and Internet access).

Significant innovations in virtualization and distributed computing, as well as improved access to high-speed Internet and a challenging economy, have accelerated demand for cloud computing solutions.

Cloud Computing can be categorised based on Service Models and Deployment Models:

Cloud Service Models

  • Infrastructure as a Service (IaaS) provides users with processing, storage, networks, and other computing infrastructure resources. The user does not manage or control the infrastructure, but has control over operating systems, applications, and programming frameworks.
  • Platform as a Service (PaaS) enables users to deploy applications developed using specified programming languages or frameworks and tools onto the Cloud infrastructure. The user does not manage or control the underlying infrastructure, but has control over deployed applications.
  • Software as a Service (SaaS) enables users to access applications running on a Cloud infrastructure from various end-user devices (generally through a web browser). The user does not manage or control the underlying Cloud infrastructure or individual application capabilities other than limited user-specific application settings.

Cloud Deployment Models

  • Private clouds are operated solely for one organization. They may be managed by the organization itself or by a third party, and they may exist on- premises or off.
  • Public clouds are open to the general public or a large industry group and are owned and managed by a Cloud service provider.
  • Hybrid clouds combine two or more clouds (private or public) that remain unique entities but are bound together by technology that enables data and application portability.
  • Community clouds feature infrastructure that is shared by several organizations and supports a specific community. They may be managed by the organizations or a third party and may exist on-premises or off.

Businesses are moving to the cloud, to lower their IT costs and increase their efficiency.
