They should use Platform as a Service (PaaS) because it offers an environment equipped with all the resources needed to develop, test, and deploy applications without the complexity of managing the underlying infrastructure.

Software as a Service (SaaS) delivers fully developed applications over the internet, which doesn't meet the requirement of building custom applications. Function as a Service (FaaS) allows users to execute code in response to events without managing servers, but it's more suitable for event-driven, serverless architectures rather than developing complete custom applications.
