Software Virtualization, in Parallels Virtual Automation documentation, stands for the
Parallels software virtualization products, such as Parallels Virtuozzo Containers for
Linux and Windows, Parallels Server Bare Metal, etc.
SSH stands for Secure Shell. It is a protocol for logging into a remote physical server or
virtual environment and executing commands.
Standard template is a solid bundle of all the necessary template files together with the
Virtuozzo virtual environments software. If newer versions of any of these packages
appear, a standard template can be correspondingly updated.
TCP (TCP/IP) stands for Transmission Control Protocol/Internet Protocol. This suite of
communications protocols is used to connect hosting physical servers on the Internet.
Template (or package set) is a set of original application files (packages) repackaged for
mounting over Parallels File System. There are two types of templates. OS Templates
are used to create new virtual environments with a preinstalled operating system.
Application templates are used to install an application or a set of applications on
virtual environments.
Parallels Containers and Parallels Server license is a special license that you should install
on the Hardware Node to be able to start using the virtual environments software. Every
Hardware Node shall have its own unique Server license.
Virtual Machine is an emulation of a physical computer by means of Parallels Server
virtualization technology. It is functionally identical to an isolated standalone server. A
virtual machine has its own virtual hardware and requires an operating system to
control its hardware. The installed operating system and its applications are isolated
inside the virtual machine and share physical hardware resources of the physical
server where the virtual machine resides.
Virtual Environment is a generic name for virtual machines and Containers.
