Virtualization is the consolidation of operating systems present on several physical servers into one physical server.

The system consolidation provides significant financial advantages. Present X86 systems in many cases have an average percentage of available resources usability (processors, working memory and data storage systems) at the level of 10-15%, which says a lot about how underused users’ current resources are.

Apart from that, the usual conception of server systems is one server – one application. In practice that means: how many different applications a company uses, at least that many servers it has. Server consolidation makes a significant improvement in exactly this part of the system.

Quality consolidation brings an increase of available resources usability of about 50-85%. When we transpose that into real systems, virtualization really reduces the number of necessary servers in the system by at least 3 to 5 times.



    • Energy savings
      Reduction of the number of physical servers reduces electricity and cooling costs. Reduce your operative costs and speed up the return of investment.
    • Lower maintenance costs
      Lower number of servers means a lower number of network equipment devices, less space inside the rack and a lower number of administrators.
    • Setting up test frameworks
      The setting up of test frameworks gives you the possibility of testing new systems or business applications without influencing your existing system. Have we mentioned that in most cases no additional hardware is needed?
    • Provisioning additional resources or whole servers
      Virtualization enables the adding of new servers or upgrade of the same ones in just a few hours, and not as in the traditional sense, a few days. Forget about order forms, installation of servers into racks, network cabling and waiting for a new system installation.
    • Increase availability
      Don’t let your employees or clients wait because of system failure. A system failure is something nobody wants. Unavailability is the main reason of clients’ discontent in today’s connected world.
    • introduce disaster recovery
      organize yourself and don’t let a breakdown ruin your business.
    • Isolate applications
      Preserve the one application/one server model.
    • Transfer your business into “cloud”
      Even though you like nice weather give the “cloudy” technology a chance it deserves
    • Reduced costs of system administration
      due to a lower number of system administrators, or vice versa – increase of productivity of system administrators who cover up to 5 times more active virtual servers in production frames in regards to the physical ones.


  • Infrastructure as a Service – IaaS

    • If we choose the IaaS model, applications, data, program equipment and operating systems remain under our administration, while the virtualization, servers, safety storage and the most important network infrastructure move under the administration of the service provider.
  • Platform as a Service – PaaS

    • With the PaaS model, only applications and data remain under our administration, while everything else is under the administration of the service provider.
  • Software as a Service – SaaS

    • If we choose this model, the service provider administers everything.
      An example of this service is the Microsoft’s product Office 365, with which in the could you get the Microsoft’s mail server Exchange, the system for instant data exchange (Lync) and a place for storage and work on documents (Sharepoint server).
