Organizations looking for ways to expand their on-premise infrastructure to add capacity on demand are investigating cloud computing. Cloud computing is a style of computing in which IT-related capabilities are provided as a service, allowing users to access technology-enabled services from the Internet, in the cloud, without knowledge of, expertise with, or control over the technology infrastructure that supports them.
With a cloud computing solution, organizations only need a minimal upfront capital expenditure for hardware, software licenses and implementation services, not the ongoing expense of administering the hardware and infrastructure software (e.g. patches). Instead, with a pay-as-you-go subscription, organizations pay a smaller recurring operating expense based only what they used which includes the hardware, software and administration.
