Free Microsoft 365 Fundamentals MS-900 Practice Question

Platform as a Service (PaaS) is the correct choice because it allows developers to focus on application development, while the cloud provider manages the underlying infrastructure, operating systems, and middleware. This accelerates development and reduces the burden of managing hardware and software updates.

Infrastructure as a Service (IaaS) requires the customer to manage the operating systems and middleware, which does not meet the company's requirement to avoid managing these components.

Software as a Service (SaaS) provides fully managed applications but does not allow for custom application development.

On-premises deployment would require the company to manage all aspects of the infrastructure and software environments.
