Describe the three forms of cloud computing.
What will be an ideal response?
Cloud computing usually takes one of three forms:
· Software as a Service (SaaS) - Applications are provided at a fee but hosted on third-party systems and accessed over the Internet (and the Web).
· Platform as a Service (PaaS) - Development platforms are available to developers for a fee and similarly hosted by third parties.
· Infrastructure as a Service (IaaS) - Unofficially known as Everything as a Service, this provides hardware and operating systems resources to host whatever the organization desires to implement, again hosted by a third party for a fee.
