Which cloud service model would be recommended to a company for hardware capacity to host a production database application?

• A. CaaS
• B. XaaS
• C. IaaS
• D. PaaS

Answer: (D)

A production database in the cloud benefits most from a model that provides scalable resources while handling the underlying management for you. PaaS offers a platform with built-in services for running applications and databases, and it includes managed database services, automated backups, patching, high availability, and easy scaling. This means you get reliable hardware-backed capacity and the ability to grow resources as demand increases without having to manage the operating system, middleware, or database maintenance tasks yourself. If you truly needed full control over the OS and database configuration, IaaS would be an option, but for hosting a production database with scalable capacity and reduced operational overhead, a platform-managed approach is typically the best fit.
