Microsoft 365 FundamentalsDescribe cloud conceptsMedium
A software development team is adopting a DevOps methodology and needs an environment that allows them to quickly provision and de-provision development, testing, and staging environments. They want to abstract away the underlying operating system and server management so they can focus on application deployment and continuous integration. Which cloud service model is most appropriate?
- ASoftware as a Service (SaaS)
- BOn-premises deployment
- CPlatform as a Service (PaaS)
- DInfrastructure as a Service (IaaS)
Show answer & explanationAnswer & explanation
Correct answer: C. Platform as a Service (PaaS)
PaaS provides a complete development and deployment environment, including operating systems, databases, and web servers, abstracting away the underlying infrastructure. This allows the development team to focus on application deployment, continuous integration, and continuous delivery (CI/CD) pipelines, aligning well with DevOps principles.
Why the other options are wrong
- A. SaaS provides a ready-to-use application, not a platform for custom development and deployment.
- B. On-premises deployment would involve significant manual effort for infrastructure management, contradicting the goal of rapid provisioning and abstraction.
- D. IaaS requires managing the operating system and middleware, which the team wants to abstract away.
Platform as a Service (PaaS)
A cloud computing service model that provides a platform and environment to allow developers to build, run, and manage applications without the complexity of building and maintaining the infrastructure.
- Provider manages OS, middleware, runtime.
- Customers manage applications and data.
- Supports rapid development and deployment.
