What is PaaS?

PaaS, or Platform as a Service, is a service that provides an application developer with a development platform to create and deploy software applications. In contrast to SaaS (Software as a Service), which only provides the end user with an application, PaaS providers typically host the application's underlying operating system and middleware services for developers.

PaaS articles describe or feature cloud computing platforms that support application development, deployment, and hosting. These articles may include comparisons between PaaS services, descriptions of how to set up an app in a specific platform, or tutorials for getting started with cloud-based development. Topics related to PaaS may also include SaaS and IaaS.
