Platform as a Service (PaaS) is the correct choice because it offers developers a comprehensive environment that includes the operating system and necessary frameworks to build, deploy, and manage applications. This model enables developers to focus on writing code and developing features without needing to manage the underlying infrastructure, which includes hardware, operating systems, and runtime environments.

PaaS environments often come pre-loaded with tools and libraries, along with various services for integration, testing, and deployment, which streamline the development process. This allows developers to quickly create applications and scale them without getting bogged down by server maintenance or network configurations.

In contrast, other models such as Infrastructure as a Service (IaaS) provide more control and flexibility over the infrastructure but require the management of operating systems and middleware by the developers. Software as a Service (SaaS) abstracts away all the underlying layers, providing fully functional applications without any development requirements. Database as a Service (DBaaS) focuses specifically on database management rather than application development frameworks.
