Parallels Virtuozzo Containers 4.0 Now Available

Server Virtualization Software Delivers on the Promise of the "Virtualized
Data Center"

RENTON, Wash., January 28th, 2008 - Parallels, Inc. (formerly SWsoft) today
announced that the latest version of its container-based server
virtualization software -- Parallels Virtuozzo Containers -- is now
generally available. Version 4.0 includes enhancements and features
designed to improve usability, data center management and business
continuity.

"The ever-changing needs of today's enterprise data centers call for a
virtualization solution that is flexible and delivers high performance,"
said Serguei Beloussov, CEO of Parallels. "With the release of Parallels
Virtuozzo Containers 4.0, we are launching the next wave of virtualization,
including a suite of products that help IT administrators effectively
manage their growing virtual infrastructures."

Beloussov continued that Parallels customers are already doing large-scale
virtualization deployments, including service provider data centers and
software-as-a-service applications. "Parallels offers the right
technological approach coupled with the best economics to deliver a
comprehensive suite of virtualization and automation products for any
hardware or software environment," said Beloussov.

Parallels Virtuozzo Containers is different from traditional hardware
virtualization solutions in that it dynamically partitions a single Windows
or Linux operating system instance into highly efficient and scalable
virtual environments or "containers".

By delivering native server performance, Virtuozzo virtualization can be
used with performance-sensitive workloads such as Microsoft SQL Server and
Oracle databases that are not practical with other virtualization solutions
due to their associated overhead and the performance penalties that are
incurred.

Also, Parallels Virtuozzo offers three times the density or more versus
other solutions, which permits data center managers to maximize the number
of virtual containers per each physical server. In fact, Virtuozzo is the
only virtualization solution that enables dozens to hundreds of containers
to immediately and automatically leverage hardware, resulting in
exceptional data center efficiency from administrative, ROI and
energy-consumption perspectives.

Along with the increased density capabilities, IT administrators can reduce
operating system sprawl in the data center by using Virtuozzo.

"We were impressed by the Beta and are looking forward to implementing
Virtuozzo 4.0," said Robert Berry, Director of Technical Services, Homes &
Land Magazine. "The new centralized management and networking options in
the tools will make managing our virtualized data center even easier."
"With the Virtuozzo product, Parallels is focused on taking virtualization
to the next level," said John Humphreys, Program Vice President with IDC's
Enterprise Platform Group. "By virtualizing above the operating system,
customers get both the benefits of hardware reduction and a reduction in
the number of operating system images they need to run to support their
applications."

"As virtualization continues to proliferate in data centers and on
desktops, Intel is delivering leading platform capabilities and performance
to foster the growth," said Diane Bryant, Vice President and General
Manager of Intel's Server Platforms Group. "Parallels Virtuozzo 4.0's
manageability tools, ease-of-use and reliability take advantage of the
performance improvements with Intel's latest generation of Quad Core Xeon
and Itanium processors and make it a leading virtualization solution."

Parallels Virtuozzo Containers 4.0 offers new features and functionality in
several key areas:

* Business Continuity - Parallels Virtuozzo Containers 4.0 includes several
new options to drive uptime, such as Windows Server 2003 and Red Hat
clustering services. In addition, Parallels Virtuozzo Containers 4.0
delivers a comprehensive set of backup enhancements.

* Ease of Use and Manageability - Version 4.0 extends the already
significant resource management in Parallels Virtuozzo Containers with the
inclusion of virtual CPU improvements, burstable CPU limits, hardware
device forwarding, hardware device sharing and more.

* Efficiency - Version 4.0's architectural enhancements provide even higher
levels of stability and performance. New efficiency-driving features
include real-time optimization of hardware resources, and an improved
Virtuozzo file system that speeds common management tasks and more
effectively utilizes hard disk resources.

Virtuozzo 4.0 also introduces the Parallels Infrastructure Manager, a
powerful tool for managing the Virtualized Data Center that enables IT
administrators to efficiently manage their infrastructure from anywhere.
The Parallels Infrastructure Manager includes a number of important
features such as:

* Enhanced Permissions - Includes role-based security and audit, Microsoft
Active Directory support and LDAP integration.

* Newly Designed Management Tool - Easier assessment of resources and
assets via powerful dashboards.

* Large Scale Deployment and Management Capabilities - Includes application
and OS templates as well as centralized data center management, providing
logical views of the data center.
