Server Virtualization

Server Virtualization is the process of masking or hiding server resources from server users including the identity of physical servers, processors, and operating systems. Servers host files and applications on networks and must be powerful. Servers are often used for a specific task that needs a dedicated machine because some applications may conflict with each other. Although this approach can streamline a network, it can also require a lot of space as networks grow and become more complex. Data centers can become overcrowded and require a lot of power to operate them and keep them cool.

“Each virtual server can efficiently use the space available on the physical server.”

Virtualization of servers can prevent the need for more space by using specific software to convert physical servers into several virtual machines. Each virtual server can run its own operating system and can efficiently use the space available on the physical server.


There are numerous other benefits to using virtualized servers including:

  • Energy savings: Using virtualization greatly reduces the amount of power required to operate the servers and keep them cool. This gives your company a much smaller energy footprint and protects the environment.
  • Create Quality Assurance lab environments: You can easily create a test, QA, or development environment without needing a separate physical server. Each environment can operate on its own isolated network without large initial expenditures by using virtualization.
  • Easy migration: Migrating to new systems can be done quickly and easily with virtualized servers.
  • Larger available capacity: With physical servers, adding more capacity can take weeks to accomplish. Servers must be obtained, shipped, and installed. Virtualized servers can provide almost instantaneous capacity, increasing productivity and decreasing downtime.
  • Cost savings: Virtualization provides a large ROI by reducing: space needed for servers, salaries for multiple employees needed to manage servers, cost for infrastructure including cabling and other hardware, and energy costs.
  • Remove application incompatibility issues: Applications that are not compatible can be run from a different virtualized server without the need for additional physical servers.
  • Prevent underutilization of servers: One physical server can accommodate several virtual machines, preventing underutilized server space. Many physical servers are dedicated to one application or operating system, which does not maximize the potential for the server.
  • Enable the use of legacy applications: Older applications may not be compatible with newer operating systems or hardware. You can encapsulate the entire operating system which runs the legacy application within a virtual server to ensure there are no compatibility issues.
  • Easier backup and disaster recovery: Full backups can be accomplished quickly. Snapshots can be acquired throughout the day to ensure data is up-to-date. In the case of disaster, data can be restored with very little downtime because virtual machines are hardware-independent, meaning they are not tied to a physical server.
  • Migration to cloud: More and more companies are using cloud environments. Using virtualized servers prepare you for a future migration to cloud services.

Virtualized servers provide many benefits and mitigate typical pain points of IT.
