Which is a cloud service model category?

The chosen answer, PaaS, represents one of the key cloud service model categories. Platform as a Service (PaaS) provides a platform allowing customers to develop, run, and manage applications without the complexity of building and maintaining the infrastructure associated with developing and launching applications. This model enables developers to focus on coding and deploying their applications while the service provider manages the underlying hardware, operating system, and middleware.

PaaS facilitates scenario-specific capabilities such as analytics or development tools, allowing for quick and efficient application development and deployment. It also promotes collaboration among geographically dispersed teams, as the platform can often be accessed through the internet, enhancing productivity and innovation.

Other cloud service models exist, such as Infrastructure as a Service (IaaS) and Software as a Service (SaaS), which serve different purposes, but PaaS is specifically designed for application development.
