Virtuozzo for Virtualization :: VPS

[eUKShane]

Virtuozzo creates isolated, secure virtual private servers (VPS Hostings) or virtual environments on a single physical server enabling better server utilization, ensuring guaranteed resources and preventing applications from conflicting. Each VPS Hosting performs and executes exactly like a stand-alone server; VPS Hostings can be rebooted independently and have users, IP addresses, processes, system libraries and configuration files.

As an Operating System virtualization solution, the unique architecture enables the most efficient use of hardware, software and management resources. The light overhead and efficient design of Virtuozzo makes it the right virtualization choice for server consolidation, disaster recovery and all production servers with live applications and data.

Server Consolidation

Application and IT managers have become accustomed to dedicating a physical server to each application to ensure that there are no application conflicts and that there is sufficient room for growth. With today’s high powered servers the single application approach leads to extremely low utilization rates, and hardware is only a small subset of the total cost of server ownership.



Virtuozzo provides full isolation between applications and its lean architecture allows a high server density. The unique Virtuozzo architecture further accelerates the cost savings by reducing software licensing and support costs and through extensive management tools that help automate server management tasks. VPS Hosting consolidation can also be deployed transparently to users making the consolidation much easier for IT.

Disaster Recovery/High Availability
Securing and making data available is extremely important and most organizations plan to minimize the impact of server outages. Virtuozzo can be a flexible and cost-effective component of every disaster recovery category. There are three categories of disasters that fall on business applications and servers:



Actual Disasters
When a server resource becomes completely unavailable, there are many approaches to recovering data and making or keeping the application available. Each approach is dependent on the application and organization’s requirements for recovery time.

Virtuozzo Advantage: Enabling Cost-effective DR Solutions
Virtuozzo can be a cost-effective component of any disaster recovery/ high availability solution, from an always available solution, to a fast recovery or backup recovery solution. Virtuozzo is the perfect solution for housing redundant servers that can be activated as necessary. Virtuozzo’s mean time to repair (MTTR) is much shorter than many other options because of the smaller server virtualization footprint. It also has a much faster boot time because only the processes and data are booting, the operating system is already available.

Virtuozzo Advantage: Proactive Disaster Mitigation
Virtuozzo migration capabilities allow VPS Hostings to be moved in real-time with near-0 downtime (keeping the application available through the migration until the last few seconds), and no SAN is required. Any threat of system failure or impending catastrophic event can be minimized by moving VPS Hostings to any Virtuozzo server with any hardware configuration in the time of data transfer.

Virtuozzo Advantage: Flexible Resource Management
Applications virtualized on Virtuozzo enjoy complete flexibility of resource management, resources maybe added or reduced in real-time without service interruption. Overloaded applications can quickly and easily be provided with more resources.

Storage Consolidation
Storage is an unavoidable reality of IT departments. Server after server fills up with data that users require, and often there is little hope of ever retiring data from expensive and aging server resources. Virtuozzo provides a new solution for consolidating and managing storage resources. Typically, server virtualization isn’t a part of a storage consolidation strategy, but Virtuozzo is a cost-effective alternative to other large-capacity storage solutions. Virtuozzo enables retaining the same network addressability and appearance to the end users, maintaining the end-user experience and comfort level and producing a completely transparent migration from aging server resources. At the same time, virtualizing the data in to virtual private servers enables many management benefits and a significant savings by utilizing a common OS on the server. Virtuozzo includes these helpful management capabilities that ease management tasks and ensure data availability: backup and recovery, migration and patch management. Create the most cost-effective storage infrastructure with better utilization and reliability.
