Introduction
The Parallels Virtuozzo Containers OS virtualization model is streamlined for the best performance,
management, and efficiency. At the base resides a standard Host operating system which can be
either Windows or Linux. Next is the virtualization layer with a proprietary file system and a kernel
service abstraction layer that ensure the isolation and security of resources between different
Containers. The virtualization layer makes each Container appear as a standalone server. Finally,
the Container itself houses the application or workload.
The Parallels Virtuozzo Containers OS virtualization solution has the highest efficiency and
manageability making it the best solution for organizations concerned with containing the IT
infrastructure and maximizing the resource utilization. The Parallels Virtuozzo Containers complete
set of management tools and unique architecture makes it the perfect solution for easily
maintaining, monitoring, and managing virtualized server resources for consolidation and business
continuity configurations.

The primary audience for this guide is anyone who is intended to deploy one or several applications
in their Containers and looking for ways to do it with the maximal level of efficiency. To complete all
the operations described in this guide, no more than basic Linux administration habits is required.
