Virtual Machine (VM)

Hypervisor/Virtual Machine (VM)

A Hypervisor/Virtual Machine (VM) is the virtualization/emulation of a computer.

It, as an application in an OS, uses OS image to act as a separate computer.

Host is the OS that contains the VM while Guest is the OS that is installed to the VM.

Some VM examples:

Runtime

Runtime is when a program is running (or being executable). That is, when you start a program running in a computer, it is runtime for that program. 

The runtime engine typically provides a foundation of routines and functions that the application requires as it performs tasks. 

runtime environment/system loads applications and has them run on a platform. 

A software program is commonly defined as a set of instructions, or a set of modules or procedures, that allow for a certain type of computer operation. The term is also often used interchangeably with terms like “software application” and “software product.”

Example of Container managers
