A small business is evaluating cloud services for their new online store. They need a solution that provides managed databases, message queues, and object storage without requiring them to provision or manage underlying servers. Which cloud service model best fits these requirements?
- ASoftware as a Service (SaaS)
- BInfrastructure as a Service (IaaS)
- CFunction as a Service (FaaS)
- DPlatform as a Service (PaaS)
Show answer & explanationAnswer & explanation
Correct answer: D. Platform as a Service (PaaS)
PaaS provides a complete development and deployment environment without the need for customers to manage the underlying infrastructure, including servers, operating systems, or networking. This aligns with the need for managed databases and message queues.
Why the other options are wrong
- A. SaaS provides a complete, ready-to-use application, not a platform for building one.
- B. IaaS provides virtualized computing resources but requires the user to manage operating systems and applications.
- C. FaaS is a subset of serverless computing, focusing on event-driven functions, not broader platform services.
Platform as a Service (PaaS)
A cloud computing service model that provides a platform allowing customers to develop, run, and manage applications without the complexity of building and maintaining the infrastructure.
- Managed infrastructure and operating system
- Focus on application development and deployment
- Includes databases, middleware, development tools
