Cloud Computing Providers
 
What is the difference between software-as-a-service providers; infrastructure-as-a-service vendors and platform-as-a-service vendors in reference to cloud computing?

Software as a Service (SaaS) is a software distribution model in which applications are hosted by a vendor or service provider and made available to customers over a network, typically the Internet.

Infrastructure as a Service is a provision model in which an organization outsources the equipment used to support operations, including storage, hardware, servers and networking components. The service provider owns the equipment and is responsible for housing, running and maintaining it. The client typically pays on a per-use basis.

Actually, the SaaS, IaaS and PaaS are the three main original service model of cloud computing. SaaS is used to provide software as a service, where you just have to use the software and pay for it. PaaS is used to offer platform as a service, where programmers and web developers use it to create various software & applications. Whereas, IaaS is formed to provide infrastructure as a service, where organizations outsource their equipments that supports their business operations which includes storage, hardware, servers, networking, etc... In IaaS, the equipments are owned by the IaaS provider and the user is charged on the pay-per-basis.

Just like these three cloud service models, there are many others formed by various companies based on the services they offer in the cloud.
