Parallels^® Parallels^® Virtuozzo Containers Basics

Designed for the Cloud, Parallels® Virtuozzo Containers is the industry-leading virtualization software for the Cloud and is designed to provide the highest levels of performance, manageability and selfservice. Parallels Virtuozzo Containers allows diverse and incompatible applications on a single physical machine, letting companies use hardware, software and data center resources and manage workloads with maximum efficiency. Parallels Virtuozzo Containers enables the broadest set of profitable services for hosting providers.

Parallels^® Virtuozzo Containers creates multiple isolated Virtual Private Servers (VPSs) on a single physical server to share hardware, licenses and management effort with maximum efficiency. Each VPS performs and executes exactly like a stand-alone server for its users and applications as it can be rebooted independently and has its own root access, users, IP addresses, memory, processes, files, applications, system libraries and configuration files. Light overhead and efficient design of Parallels^® Virtuozzo Containers makes it the right virtualization choice for production servers with live applications and real-life data.

Dynamic Real-time Partitioning
Partition a physical server into 100s of VPSs, each with full dedicated server functionality

Resource Management
Assign and control VPS resource parameters and re-allocate resources in real-time

Virtualization
Move VPSs and its application(s) between physical servers transparently with near-zero downtime

Mass Management
Manage 1000s of VPSs as easily as a single server and 100s of physical servers in unified way

Due to Parallels^® Virtuozzo Containers fair-sharing technology, each partition can have almost the same power as the full server.
Create hundreds of partitions on one server, each with full dedicated-server functionality – root access, rebootable, ability to install any application, change any file.

Mainframe-like level of resource utilization, monitoring and control on standard, inexpensive hardware. In addition to standard CPU, disk space and network I/O, it also manages memory (user, kernel and disk cache) and disk I/O. VPSs are fully isolated with minimum and maximum resource guarantees.

OS Virtualization

Drag and drop a live site or hundreds of running applications to another physical server for planned system maintenance or hardware upgrades with only a few seconds of planned downtime.
Dramatically improves availability.

Mass Management

Create your own application and OS templates. Group them together and mass deploy the updates and applications to specific systems. Integrated sophisticated versioning database for all system files, libraries, and applications. Allows upgrade exceptions on a per system basis.
Improve system uptime. Improve security. Reduce IT costs.
