Which cloud model would you choose to deploy your own applications while the provider manages the platform and infrastructure?

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

Answer: (B)

Think about who handles what in cloud service models. If you want to run your own code but the provider takes care of the underlying platform and infrastructure, you’re looking for a platform that abstracts the runtime and middleware. In this setup, the provider manages the servers, storage, networking, operating system, and runtime environment, while you focus on deploying your application and managing its data. This lets you ship features quickly without worrying about patching the OS or configuring the runtime. That’s what platform as a service offers. By contrast, infrastructure as a service puts more control in your hands over the OS and applications but requires you to manage more of the stack, software as a service provides a ready-to-use application with minimal customization, and desktop/service-oriented models aren’t about hosting your own apps. So the best fit for deploying your own applications while the provider handles the platform and infrastructure is platform as a service.
