Which statement best describes Platform as a Service (PaaS)?

• A. Hardware and software infrastructure for the development of business applications
• B. End-user email services
• C. On-premises data storage
• D. Customer relationship management platform

Answer: (A)

Platform as a Service provides a cloud-based platform that includes the runtime environment, development tools, middleware, and databases needed to build, test, and deploy applications, while the provider manages the underlying hardware, OS, and infrastructure. This focus on the platform layer and developer tooling is what distinguishes PaaS from other models.

End-user email services are typically SaaS, offering ready-to-use applications. On-premises data storage is not cloud-based. A customer relationship management platform is usually delivered as SaaS.
