A development team wants to deploy an application quickly without managing the underlying operating system or infrastructure. They only want to focus on writing code and configuring application-specific settings. Which cloud service model is most suitable for this requirement?
- APlatform as a Service (PaaS)
- BFunction as a Service (FaaS)
- CInfrastructure as a Service (IaaS)
- DSoftware as a Service (SaaS)
Show answer & explanationAnswer & explanation
Correct answer: A. Platform as a Service (PaaS)
Platform as a Service (PaaS) provides a complete development and deployment environment, allowing developers to focus solely on their application code without managing operating systems, servers, or networking infrastructure.
Why the other options are wrong
- B. FaaS (serverless computing) is a subset of PaaS, but PaaS is the broader category that encompasses the described scenario of deploying a full application without OS management.
- C. IaaS requires the user to manage the operating system, middleware, and applications, which goes against the team's desire to avoid OS management.
- D. SaaS provides a complete, ready-to-use application, not a platform for custom development.
Platform as a Service (PaaS)
A cloud service model that provides a complete development and deployment environment in the cloud, with resources that enable organizations to deliver everything from simple cloud-based apps to sophisticated, cloud-enabled enterprise applications.
- Users manage applications and data.
- Cloud provider manages OS, middleware, runtime, infrastructure.
- Focuses on rapid application development and deployment.
Memory trick: PaaS is the 'platform' for developers to 'build' their code.
