Platform-as-a-Service (PaaS) has always been the unappreciated sibling of the cloud computing service model trio. Existing in the dark shadow of the most widely adopted Software-as-a-Service (SaaS) and foundationally powerful Infrastructure-as-a-Service (IaaS), the third service model is often misunderstood and widely ignored.
PaaS provides a platform allowing customers to develop, run, and manage web applications without the complexity of building and maintaining the infrastructure. Its unique power is associated with developing and deploying applications.
