Server Virtualization

The virtualization of servers is the method of choice to use the own hardware as effectively as possible.

Server virtualization means to host multiple server instances on the same hardware. The advantage lies in a much better utilization of the hardware. Virtualization leads directly to savings in hardware costs, lower operating costs and a significantly lower maintenance

Cluster virtualization in turn allows the grouping of multiple servers into a single unit, a so-called "single system". Thus, the cluster is as easy to manage as a single workstation.

Areas of application

Virtual servers have multiple uses, such as:

  • Disaster Recovery Solutions
  • High Availability Solutions
  • Server Consolidation
  • Test and development environments
  • Virtual infrastructure
  • Migration of old systems / legacy applications

 

Benefits

Efficiency: By consolidating the server a higher CPU utilization is achieved.

Stability: virtualization is more secure, since an application error or system crash in a virtual machine does not affect other virtual machines that are running on the same system.

Cost reduction: Virtualization allows a very effective use of existing capacities. By consolidating the server the cost of the acquisition, operation, cooling and hosting of hardware components and, not least, the staff costs for the administration of additional systems, can be significantely reduced.

Productivity: A once generated virtual machine can be cloned by simply copying the associated files or logical drives. The time required for the deployment-time of a new system can thereby be reduced from several days to a few minutes.

Portability: The use of abstract entities within the virtual machine and the virtual encapsulation of data on virtual disks, the machines can easily be ported between different physical systems .

Availability: The ease of deployment and migration of virtual machines makes planned downtime, unnecessary, at the same time it is also significantly less unplanned downtime due to system errors.
