The correct answer is: A. Infrastructure Service
A virtual machine (VM) is a software program that creates a simulated computer environment. It behaves like a physical computer, with its own CPU, memory, storage, and network interface. VMs can be used to run multiple operating systems on a single physical computer, or to isolate applications from each other.
VMware is a software company that develops virtualization products. Its flagship product is VMware vSphere, a suite of products that enables businesses to run multiple operating systems on a single physical computer. VMware vSphere is an example of an infrastructure service, which is a service that provides the foundation for other services. Infrastructure services include things like networking, storage, and compute.
Platform services are services that provide a platform for other applications to run on. They include things like operating systems, databases, and web servers. Software services are applications that are designed to be used by end users. They include things like word processors, spreadsheets, and email clients.
In conclusion, VMware is an example of an infrastructure service because it provides the foundation for other services, such as running multiple operating systems on a single physical computer.
