Cloud & Hosted Services
The applications that are delivered include software as a service (SaaS) and hardware as a services (HaaS).
Cloud computing users can avoid capital expenditure (CapEx) on hardware, software, and services when they pay a provider only for what they use. Consumption is usually billed on a utility (e.g., resources consumed, like electricity) or subscription (e.g., time-based, like a newspaper) basis with little or no upfront cost.
