Microsoft Azure Fundamentals AZ-900 Practice Question

Platform as a Service (PaaS) is the correct answer because it provides a platform allowing customers to develop, run, and manage applications without the complexity of building and maintaining the infrastructure typically associated with developing and launching an app. It abstracts much of the system administration effort needed for setting up environments and lets developers focus on writing code. Infrastructure as a Service (IaaS) would not be the ideal choice here because it does provide the virtualized hardware but would still require the company to manage the servers and software stack. Software as a Service (SaaS) is also not correct because it offers completed products to end-users, which does not align with the company's goal of developing a custom application. Desktop as a Service (DaaS) is incorrect because it mainly provides virtual desktop environments, not a development platform.
