Platform as a service (PaaS) is a kind of cloud computing service. A PaaS

provider offers a platform on which clients can develop, run and manage

applications without the need of building the infrastructure.

In PAAS clients save time by not creating and managing infrastructure

environment associated with the app that they want to develop.
