What provides a platform for companies that develop applications without the need for infrastructure?

• A. IaaS
• B. SaaS
• C. Application Streaming
• D. Platform as a Service (PaaS)

Answer: (D)

Think of a cloud model that provides a complete development and hosting environment so teams can build, test, deploy, and scale applications without worrying about the underlying servers, operating systems, or runtime setup. That model is Platform as a Service. It offers the runtime, middleware, databases, and development tools as a managed service, plus features like auto-scaling and integrated security, so developers can focus on code rather than infrastructure. This isn’t IaaS, which would leave you provisioning and managing virtual machines and OS details; it isn’t SaaS, which delivers finished software to users rather than a platform for building apps; and it isn’t Application Streaming, which primarily concerns running apps remotely. Platform as a Service best fits the description.
