Container

Container is software designed for virtualization in an isolated software environment. The creation of a container is realized through the use of isolated space. Virtualized names – necessary components, libraries for the functioning of the virtual environment of the container. Tools that are outside the container are inaccessible to the virtualized space.

Virtual machines and containers have significant differences: Virtual machines use a separate pool of resources from the OS. The container in turn requires resources, and components are shared with the main OS. The container is faster to start up and the degree of load on the container during startup is much lower.

Some containers are only available to the API or the OS. For example, a Linux container will not work without a Linux API. The container management tool is PowerShell, but it is slowly losing popularity. Docker is more modern and the management commands are relevant for both Windows and Linux.
