Definition

Cloud Computing is the use of Internet computer and software technologies to provide a variety of computer and software services.

Which allow customers to leverage Cloud supplier's hardware, network, software, and storage.

It is a way to increase capacity or add capabilities on the fly without investing in new infrastructure, training new personnel, or licensing new software.

This allows the consumer to focus on their business and not on being an IT supplier.
