Which of the following would be basically the same whether an operating system was run on a virtual server or a physical server?

Whether a server is physical or virtual, it requires the same security settings, and every virtual server, like every physical server, requires a license. While RAM and storage needs would be the same, one advantage of employing a virtual machine is the ability to run multiple servers on a single piece of computer hardware, resulting in lower overall hardware costs and lower maintenance costs. Virtual servers are far more portable than physical servers, allowing them to be readily transferred from one piece of hardware to another.
