Cloud computing is the strategy of using remote servers hosted on the Internet to store, manage, and process data rather than using a local server or personal computer's hard disk. It has evolved over 50 years and includes public, private, community, and hybrid cloud deployment models. Public cloud uses computing resources over the Internet on a pay-as-you-go basis while private cloud infrastructure is owned entirely by a single organization.

the Internet to store, manage, and process data, as opposed to a local, or on-

5. Industry analysts say that cloud computing has evolved over some fifty years of
technological evolution. There are currently several different cloud deployment
models:
• Public cloud is where computing resources are used by different organizations
over the Internet on a pay-as-you-go model.
• Private cloud is where the cloud infrastructure is owned entirely by a single
organization, and can be located either on site or off site.
• Community cloud is where the cloud infrastructure is owned and shared by many
organizations with common concerns.
• Hybrid cloud is a combination of any of the other cloud models, and connected
by standardized or proprietary technology.
