In cloud service models, which option provides a platform for building and deploying apps while the provider handles the underlying infrastructure?

• A. Platform as a Service (PaaS)
• B. Software as a Service (SaaS)
• C. Cloud Networking
• D. Content Delivery Network

Answer: (A)

Platform as a Service (PaaS) gives developers a ready-made platform to build, test, and deploy applications, while the provider takes care of the underlying resources. The vendor manages the infrastructure—servers, storage, networking—and also handles the runtime environment, middleware, operating system, and often managed services like databases. This lets you focus on writing and deploying code without worrying about managing servers or runtime. It differs from Software as a Service, where you use an application delivered over the cloud, and from infrastructure-focused models where you manage more of the stack yourself. Examples include Google App Engine, Heroku, AWS Elastic Beanstalk, and Azure App Service.
