Platform as a Service (PaaS) is a cloud computing model that provides a complete, managed environment in the cloud for building, testing, deploying, running, and scaling applications. In a PaaS model, the cloud service provider manages the physical infrastructure, virtualization layer, operating system, and runtime middleware, allowing developers to focus solely on their code and data.
Compared to alternative service models, PaaS offers the ideal balance between developer control and cloud management. It directly satisfies the organization's goal of rapid application development and deployment while offloading OS and web server maintenance.
