Most organisations run a number of applications and in many cases, more would be used if it wasn't for the cost of purchasing and managing new hardware to host them. Virtualisation is changing that and where multiple servers were required before, a single server with Virtualisation applications can do the work of multiple servers.
Put simply, virtualisation allows one server to host several virtual servers with each one running its own operating system. The following are some of the key features of the virtual servers:
Multiple applications and operating systems can be supported within a single physical system.
Servers can be consolidated into virtual machines on either a scale-up or scale-out architecture.
Computing resources are treated as a uniform pool to be allocated to virtual machines in a controlled manner.
Virtual machines are completely isolated from the host machine and other virtual machines. If a virtual machine crashes, all others are unaffected.
Data does not leak across virtual machines and applications can only communicate over configured network connections.
Complete virtual machine environment is saved as a single file; easy to back up, move and copy.
Standardised virtualised hardware is presented to the application - guaranteeing compatibility.
Using a virtual environment
There are a number of ways in which the virtual environment can be used and the solutions we provide around virtualisation typically fall into one of the following areas:
There are many benefits and significant cost savings can be achieved, as very often, existing servers aren’t being used to their full capacity. There are also performance benefits for testing and development projects allowing for a much quicker transition, while disaster recovery is also simplified.
