Microsoft 365 Fundamentals MS-900 Practice Question

Platform as a Service (PaaS) is the most suitable model because it provides a platform allowing developers to build, run, and manage applications without dealing with the underlying infrastructure. PaaS offers the necessary tools and services to support the complete lifecycle of application development and deployment.

Infrastructure as a Service (IaaS) requires you to manage the operating systems, middleware, and runtime environments yourself.

Software as a Service (SaaS) delivers fully managed software applications to end-users, which doesn't meet the need for custom application development.

On-Premises Deployment would require you to manage all aspects of the infrastructure, increasing setup time and resource requirements.
