PaaS (Platform as a Service)

Brings virtualized servers on which customers can run present applications or develop new ones without having to burden about keeping the operating systems, server hardware, load balancing or computing capacity.

•   A cloud computing platform dynamically supplies, configures, re-configures and de-provisions servers as needed to manage with increases or decreases in demand. This in certainty is a distributed computing model, where many services collected to deliver an application or infrastructure demand.
• These vendors deliver APIs or development platforms to create and run applications in the cloud – e.g. using the Internet.
•   Managed Service providers with application services delivered to IT departments to monitor systems and downstream applications such as virus scanning for e-mail are frequently included in this kind.

Examples are Microsoft's Azure, SalesForce.com, Google Maps, ADP Payroll processing, and US Postal Service offerings.
