Cloud computing is a model that allows for on-demand access to shared computing resources over a network. It has evolved from concepts dating back to the 1950s and has become widely accessible since services like Amazon Web Services were launched in 2006. The document outlines different types of cloud services, including public, private, hybrid, and community clouds.

The software and storage for your account doesn't exist on your computer - it's on the service's computer cloud. 2 of 19

- 15. i) Public cloud: The simplest way to describe a public cloud is an infrastructure that is used by the public and provided by a government, organization or other companies. ii) Private cloud: A private cloud is used exclusively by an organization and the cloud provider is either the organization themselves or a third party . iii) Hybrid cloud: A hybrid cloud is an infrastructure that combines public and private clouds. It consists of a composition of two or more clouds. iv) Community cloud: A community cloud is used by a community of consumers from various organizations that share common views. This particular setup may be controlled and maintained by a third party or by the organizations themselves. Types of Cloud 15 of 19
