Which cloud service model allows users to deploy their own applications?

The Platform as a Service (PaaS) model is designed specifically to allow users to develop, run, and manage applications without the complexity of building and maintaining the underlying infrastructure. PaaS provides a platform that includes everything needed to build applications, such as runtime environments, development frameworks, libraries, and tools for application design and deployment. This model enables developers to focus on writing code and building applications, simplifying the deployment process significantly.

PaaS environments often facilitate collaboration among development teams and can be configured to seamlessly integrate with various databases, web services, and middleware, enhancing the application development process. Moreover, because the infrastructure is provisioned and managed by the service provider, users can leverage the scalability and flexibility of the cloud without worrying about the underlying hardware or server management.

In contrast, Infrastructure as a Service (IaaS) provides raw computing resources and necessitates a higher level of management from the user, which includes setting up and maintaining the operating systems and application environments. Software as a Service (SaaS) delivers fully functional applications over the internet and does not allow users to deploy their own applications, as users utilize the software provided by the provider. Function as a Service (FaaS) allows users to run individual functions in response
