Platform as a Service (PaaS) is designed to sit on top of Infrastructure as a Service (IaaS) and provides a framework for developers to create applications without needing to manage the underlying infrastructure. PaaS offers a variety of tools and services that facilitate application development, such as middleware, database management systems, development frameworks, and runtime environments. This allows developers to focus on writing code while the PaaS manages the complexities of underlying resources such as servers, storage, and networking.

In contrast, Cloud Storage, Infrastructure as a Service, and Software as a Service each serve different purposes within the cloud service model. Cloud Storage provides scalable storage solutions but does not directly aid in application development. Infrastructure as a Service delivers virtualized computing resources but does not offer the application development tools or environment found in PaaS. Software as a Service delivers completed software applications to end users, rather than providing an environment for developers to build their own applications. Thus, PaaS is the service specifically designed to enhance and integrate with application development frameworks atop IaaS.
