Which service model provides a development platform for building and deploying applications?

• A. IaaS
• B. PaaS
• C. SaaS
• D. Private Cloud

Answer: (B)

Platform as a Service (PaaS) provides a development platform for building and deploying applications by delivering the runtime, frameworks, libraries, and development tools as a service. This lets developers focus on writing code and deploying it, while the platform handles the underlying servers, operating systems, middleware, and scaling. Because the environment is managed, you can quickly implement, test, and push updates, and the service often includes built-in deployment pipelines and integration with databases and services. In comparison, infrastructure as a service offers raw computing resources you configure and manage yourself; software as a service provides ready-to-use applications managed by the provider; and private cloud is a deployment model describing where resources are hosted, not a software service model.
