CompTIA A+ Core 1 (220-1201)Virtualization and Cloud ComputingEasy
A small startup is looking for a cloud computing model that provides pre-built development environments, including operating systems, databases, and web servers, allowing their developers to focus solely on writing application code. Which cloud service model best fits their needs?
- AInfrastructure as a Service (IaaS)
- BFunction as a Service (FaaS)
- CPlatform as a Service (PaaS)
- DSoftware as a Service (SaaS)
Show answer & explanationAnswer & explanation
Correct answer: C. Platform as a Service (PaaS)
Platform as a Service (PaaS) provides a complete development and deployment environment in the cloud, abstracting away the underlying infrastructure. This allows developers to focus on application code without managing servers, operating systems, or networking.
Why the other options are wrong
- A. IaaS provides virtualized computing resources, but the user is responsible for managing the OS, middleware, and applications.
- B. FaaS (serverless computing) executes code in response to events, but PaaS is a broader category for full development environments.
- D. SaaS provides ready-to-use software applications over the internet, with no control over the underlying platform or infrastructure.
Platform as a Service (PaaS)
A cloud computing model that provides a complete development and deployment environment in the cloud, including operating systems, programming language execution environments, databases, and web servers.
- Developers focus on application code, not infrastructure.
- Cloud provider manages OS, middleware, and runtime.
- Common for web application development and deployment.
