Virtual Machine

A virtual machine is associate emulation of a system. Virtual machines square measure supported computer architectures and supply practicality of a physical computer. Their implementations might involve specialized hardware, software, or a mixture.

A container may be a normal unit of computer code that packages up code and everyone its dependencies that the application runs quickly and faithfully from one computing setting to a different. A docker image may be a light-weight, standalone, feasible package of computer code that has everything required to run associate application: code, runtime, system tools, system libraries and settings.
