Microsoft Azure Fundamentals (AZ-900)Describe cloud conceptsMedium
A software development team requires a fully managed environment for building, deploying, and running their web applications. They want to focus solely on code development and avoid managing the underlying operating systems, virtual machines, or network configurations. Which cloud service type is most appropriate for their needs?
- AInfrastructure as a Service (IaaS)
- BPlatform as a Service (PaaS)
- CFunction as a Service (FaaS)
- DSoftware as a Service (SaaS)
Show answer & explanationAnswer & explanation
Correct answer: B. Platform as a Service (PaaS)
PaaS provides a complete development and deployment environment, abstracting away the operating system, virtual machines, and network infrastructure. This allows developers to focus entirely on application code, which perfectly aligns with the team's requirement to avoid managing underlying infrastructure.
Why the other options are wrong
- A. IaaS requires managing the OS and VMs, which the team wants to avoid.
- C. FaaS is for event-driven functions, not typically a full web application environment.
- D. SaaS provides a complete application; it's not for developing new applications.
Platform as a Service (PaaS)
A cloud service model that provides a complete platform for developing, running, and managing applications without the complexity of building and maintaining the infrastructure associated with developing and launching an app.
- Provider manages OS, middleware, runtime, and hardware.
- Customer manages applications and data.
- Ideal for developers to focus on code.
- Examples: Azure App Service, AWS Elastic Beanstalk.
Memory trick: PaaS empowers developers to code, freeing them from server woes.
