Gartner defines Cloud Computing Technology as a style of computing where massively scalable IT-related capabilities are provided “as a service” using Internet technologies to multiple external customers. In general, this Cloud Computing Technology refers to anything related to delivering hosted services over the internet; including Software as a Service (Saas). Cloud Computing Technologies have three defining characteristics:
■ It is sold on demand, typically by the minute or the hour
■ It is elastic, meaning each user determines the extent of their service needs
■ The service provider manages the service from end-to-end
Significant innovations in virtualization have recently garnered accelerated interest in cloud computing technology. Cloud computing services can be public or private and you can find cloud computing providers of both. In a public cloud, services are sold to anyone on the internet. In a private cloud, a hosting is provided to a limited number of people via a proprietary network or data center.
