Platform as a Service (PaaS) is the best match for the given scenario because it abstracts and manages the underlying infrastructure, provides services to support the full lifecycle of building and delivering web-based applications, and allows for easy scaling and high availability. It also supports a variety of programming languages and frameworks. While Infrastructure as a Service (IaaS) provides more control over the infrastructure, it requires management of that infrastructure, which the scenario aims to avoid. SaaS delivers complete applications but does not offer the development environment requested. Virtual desktop infrastructure (VDI) pertains to desktop virtualization and does not encompass development platform services.
