A small startup is looking for a cloud service model that allows them to quickly develop and deploy web applications without needing to manage the underlying operating systems, servers, or networking infrastructure. They want to focus solely on their application code and data. Which cloud service model best fits their needs?
- APlatform as a Service (PaaS)
- BSoftware as a Service (SaaS)
- CInfrastructure as a Service (IaaS)
- DFunction as a Service (FaaS)
Show answer & explanationAnswer & explanation
Correct answer: A. Platform as a Service (PaaS)
PaaS provides a complete development and deployment environment, abstracting away the underlying infrastructure management. This allows the startup to focus exclusively on their application code, which aligns perfectly with their requirements.
Why the other options are wrong
- B. SaaS provides ready-to-use applications; it does not allow for custom application development.
- C. IaaS requires the user to manage operating systems, applications, and some networking, which the startup wants to avoid.
- D. FaaS (serverless computing) is a subset of PaaS, but PaaS is the broader and more appropriate answer for 'developing and deploying web applications' without managing OS/servers.
Platform as a Service (PaaS)
A cloud service model that provides a platform allowing customers to develop, run, and manage applications without the complexity of building and maintaining the infrastructure.
- Focus on application development and deployment
- Provider manages OS, runtime, middleware
- Scalable and flexible development environment
