The company should utilize Infrastructure as a Service (IaaS), as it allows for the greatest level of control and customization over the environment, including the operating system, storage, and networking. Customers retain complete control over the virtual machines, as well as the choice of OS and middleware. This scenario doesn't necessarily imply the need for platform-related services such as development tools, database management, and business analytics, which are typically offered by Platform as a Service (PaaS). Similarly, Software as a Service (SaaS) provides even less control and customization as it delivers fully managed applications.
