GlossaryApplication template . A template used to install a set of applications in Containers . See also Template . Container (or regular Container ). 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, its own applications, system libraries, and so on. Containers share one Parallels server and one OS kernel. However, they are isolated from each other. A Container is a kind of 'sandbox' for processes and users. Guest operating system (Guest OS) . An operating system installed inside a virtual machine and Container. It can be any of the supported Windows, Linux, or Mac operating systems. Hardware virtualization . A virtualization technology allowing you to virtualize physical servers at the hardware level. Hardware virtualization provides the necessary environment for creating and managing Parallels virtual machines. Operating system virtualization (or OS virtualization ). A virtualization technology allowing you to virtualize physical servers at the operating system (kernel) level. OS virtualization provides the necessary environment for creating and managing Parallels Containers. OS template (or Operating System template ). A template used to create new Containers with a pre-installed operating system. See also Template . Package set . See Template . Parallels Management Console . A Parallels Server Bare Metal management and monitoring tool with graphical user interface. Parallels Management Console is cross–platform and can run on Microsoft Windows, Linux, and Mac computers. Parallels Server . A hardware virtualization solution that enables you to efficiently use your physical server's hardware resources by sharing them between multiple virtual machines created on this server. Parallels server (or physical server or server ). A server where the Parallels Server Bare Metal software is installed for hosting Parallels virtual machines and Containers. Sometimes, it is marked as Container 0. Parallels Server Bare Metal license . A special license that you should install on the physical server to be able to start using Parallels Server Bare Metal. Every physical server must have its own license installed. Parallels Virtuozzo Containers for Linux . An operating system virtualization solution allowing you to create multiple isolated Containers on a single physical server to share hardware, licenses, and management effort with maximum efficiency. Private area. A part of the file system storing Container files that are not shared with other Containers . Template (or package set ). A set of original application files (packages) repackaged for mounting over Virtuozzo File System. There are two types of templates. OS Templates are used to create new Containers with a pre-installed operating system. Application templates are used to install an application or a set of applications in Containers . UBC . An abbreviation of User Beancounter . User Beancounter . The subsystem of the Parallels Server Bare Metal software for managing Container memory and some system-related resources. Virtual Environment (or VE ). An obsolete designation of a Container . Virtuozzo File System ( VZFS ). A virtual file system for mounting to Container private areas. VZFS symlinks are seen as real files inside Containers . Virtual machine (VM) . A computer emulated by Parallels Server Bare Metal. Like a Container, a virtual machine is functionally identical to an isolated standalone computer, with its own IP addresses, processes, files, its own users database, its own configuration files, its own applications, system libraries, and so on. However, as distinct from Containers, virtual machines run their own operating systems rather than sharing one operating system kernel. |
