Virtualisation allows the IT systems to deal with the dynamically changing requirements of individual systems without the necessity of having to change the underlying physical infrastructure. On the level of physical infrastructure, individual performance parameters are assigned to individual systems and virtual instances of application servers. When it comes to virtualisation we offer services that span the entire life-cycle: architecture design, implementation, migration, operation, monitoring, and development.

The basis of the virtualisation layer is the Hypervisor, which based on the resources that were defined beforehand, simulates an HW environment that satisfies the needs of the running operating system. From a single physical server one can concurrently run multiple virtual instances. Depending on the system requirements, one physical server can host dozens of virtual servers.

The following are the main advantages of using a virtual environment:

  • Cost-effective utilization of system resources
  • Reduction of operational costs
  • Separation of the operating system from the physical HW
  • Different versions of operating systems can be run parallel on the same HW
  • Environment can be scaled according to the current needs
  • More simple environment administration and maintenance
  • Server monitoring as part of the virtualization layer.

When designing our solutions, we prefer to use the Microsoft Hyper-V and VMware vSphere virtualisation platforms. However, we have also successfully implemented projects based on the Oracle, XEN, and KVM platforms.
