Parallels^® Virtuozzo Containers

Highest Performance. Reduced Complexity. Lower Costs.

Parallels Virtuozzo Containers is an operating system virtualization solution that lets you maximize the investment in your existing server hardware. Parallels technology provides 2X — 3X more virtual servers than hypervisor solutions providing greater utilization from your infrastructure.

With today’s lean budgets, higher utilization of your existing servers represents cost savings not only in maintenance and energy costs but also from the potential elimination of new server expenditures.

Virtualization at the host operating system provides a lean, efficient virtualization layer that enables higher density ratios of virtual servers to physical servers along with complete isolation between workloads. This isolation allows multiple workloads to exist across business silos without one workload affecting the performance and security of any other.

Other features of Parallels Virtuozzo Containers 4.6:

• Intelligent Partitioning
  Small footprint of virtual servers and lightening fast management operations
• Dynamic Resource Management
  Automatic or administrator-defined control over system resources
• Mass Management
  Centralized management of virtual environment
• Live Migration (Linux version only)
  Move containers while up and fully functioning

Complete Server Virtualization Solution

Parallels Virtuozzo Containers comes with a built-in GUI interface to manage individual servers or a command line interface (CLI) for scripting and integration. The optional web-browser solution, Parallels Infrastructure Manager, provides a single console view of the complete virtualization environment on top of the ability to manage both Windows & Linux virtual servers.

Parallels Infrastructure Manager comes with a built-in backup tool to help diminish solution costs. The administrator has the ability to define backup compression ratios ensuring minimum degradation to network performance.

Using Parallels Virtuozzo Containers

Internal & Commercial Cloud Computing
Provision, provide, monitor and manage large numbers of virtualized services, hosted applications and software on demand.

Virtual Desktop Infrastructure
Parallels VDI allows the central management of desktops from the data center without heavy lifting or making any application changes.

Software as a Service (SaaS)
Templates allow multiple instances of an application to be quickly deployed across high density IT infrastructures in a matter of minutes.

Parallels Virtuozzo Containers unique form of virtualization not only eliminates complications that arise with hardware virtualization, but its impact on server performance is so minimal that the server operates at near-native levels.

Virtuozzo Performance factors:

• System Calls Parallels Virtuozzo Containers has a common kernel, no additional systems calls are created between excess layers.
• Filesystem Common data is stored only once and is available to multiple environments, significantly improving the efficiency of both the disk space and system memory. The disk space for caching is also used efficiently, caching payload rather than duplicated data.
• Filesystem Performance Parallels Virtuozzo Containers’s filesystem and efficient system call design create very small CPU usage overhead.
• Filesystem buffers/cache in memory Parallels Virtuozzo Containers places a single instance of data and cache across the server, maximizing memory efficiency.
• Memory Management Parallels Virtuozzo Containers handles memory allocation requests dynamically. Virtuozzo environments can use a lot of memory during load peaks, and users will fully benefit from running Virtuozzo on high-end servers. Applications in Virtuozzo environments can show very high peak performance.

“Virtuozzo steadily outperformed the competition and proved it was much more scalable. We use Virtuozzo to efficiently operate and expand our new server infrastructure with a dramatic 85% reduction in total costs...” — — Aron Steg,
Managing and Founding Director of SMS Central
