Application template is a template used to install a set of applications on virtual
environments. See also Template.
Container is a virtual private server, which is functionally identical to an isolated
standalone server, with its own IP addresses, processes, files, its own users database,
its own configuration files, applications, system libraries, and so on. Containers on one
and the same physical server (or Hardware node) share one OS kernel. However, they are
isolated from each other.
EZ template is built up from separate chunks of code that are uploaded from the web
every time you pick an EZ template to install in the Container. This means, that an EZ
template is not an independent package but rather a unit containing all the necessary
information about repositories from where the necessary packages will be uploaded to
the physical server.
Hardware Node is a physical server where the Parallels software is installed for hosting
virtual environments. The Hardware Node term is used in the product interface, while in
technical documentation, you will find the term physical server.
Hardware Virtualization, or hypervisor, virtualizes at the hardware level creating a
duplicate of all system resources such as operating system, CPU, memory and
configuration files.
Host Operating System (or Host OS) is an operating system installed on the physical server.
Master Server is a physical server where the Parallels Virtual Automation Management
Server component is installed.
OS template (or Operating System template) is used to create new virtual environments with
a preinstalled operating system. See also Template.
Parallels Virtual Automation is a tool designed for managing physical server and all virtual
environments residing on them with the help of a standard Web browser on any
platform.
Parallels Power Panel is an easy-to-use web-based tool designed for administering single
personal virtual environment. With Power Panel, a user with administrative access to a
virtual environment can easily perform many critical management tasks, while not
requiring access rights to the physical server:
Parallels Virtuozzo Containers (or Parallels Containers) is a complete server automation and
software virtualization solution allowing you to create multiple isolated Containers on a
single physical server to share hardware, licenses, and management effort with
maximum efficiency.
