Virtual Machines (VMs) & Virtual Private Servers (VPS)

A Virtual Machine (VM) is software or an OS that is programmed to emulate another system. Several of these virtual machines can be sectioned off from each other, allowing many to run on one system. A system virtual machine is an emulation of operation system or similar. This is sometimes used to run older operating systems, and with the amount of computing power available today, processes of the hardware can be partitioned off for use by each particular emulation. After the virtual machine is set up, it can run as if it is within the intended hardware it was designed for, and can be an exact same end-user experience. A process virtual machine is designed just to run a single program, instead of an entire operating system. These virtual machines are bound to the hardware along with the computer they run on. If aspects of the virtual machine was designed to use pieces of hardware that are not available in the emulating device, nothing will happen.


What is a Virtual Private Server? How does a VM relate to a VPS?


A virtual private server is also a virtual machine, but the system is set up to be a dedicated server. These virtual private servers are sold by internet hosting services as dedicated servers, but they are usually far cheaper than an actual physical server. These virtual private servers are usually shared on the same hardware with many others, and the hardware needs to accommodate every VPS . These are all partitioned as to be seen as a single device to the end-user. The customer who pays for VPS gains admin control of the server, allowing the customer to use the VPS for whatever is needed. Web Hosting sites usually have many different VPS hosting packages to fit the needs of any customer that comes along.
