The bigger picture

Volvo IT

Computing using dynamically scalable & virtualized resources, provided as a service over the Internet.

Cloud computing is the delivery of computing as a service rather than a product, whereby shared resources, software, and

information are provided to computers and other devices as a utility (like the electricity grid) over a network (typically the

Internet).
