Which cloud service model provides platform to deploy applications (Heroku)?

• A. PaaS
• B. IaaS
• C. SaaS
• D. DaaS

Answer: (A)

Platform as a Service (PaaS) provides a ready-to-use environment for developing, deploying, and managing applications. With PaaS, you push your code and the platform handles the runtime, middleware, scaling, and underlying infrastructure, so you can focus on building the app. Heroku is a prime example of this model: you deploy your app and the service takes care of servers, operating systems, updates, and scaling as needed. IaaS offers raw infrastructure—virtual machines, storage, and networks—while you’re responsible for installing and managing the operating system and runtime. SaaS delivers finished software accessed over the internet, not a platform for deploying your own code. DaaS (Desktop as a Service) is about providing virtual desktops rather than a deployment platform for applications. So the model that best fits “a platform to deploy applications” is PaaS.
