In computing, Virtulisation refers to the act of creating a virtual (rather than actual) version of something, including but not limited to a virtual computer hardware platform, operating system (OS), storage device, or computer network resources.
The current commonest use of this technology is to have a single hardware platform (a server) running an OS that provides a Virtulisation platform. On this platform runs one or more separately configured "Virtual machines" (Clients) These Virtual machine exits as a single transportable computer file that can be run on other servers running an identical Hosting OS
At Net-gen we have experience in deploying, running and maintaining Virtulisation Hosts and clients. Our preferred Hosting platform is Microsoft Hyper V 2012R2 but we are well versed in Virtulisation using older Microsoft Platforms and Oracle (Sun) Virtulisation products. Three of our primary servers are run on 2 virtualised hosts (Hyper V 2012R2) and we also run an off-site Virtulisation platform (also Hyper V 2012R2)to act as a replication/backup/resilliance measure, connected to our main network through a secure VPN.
With the advent and emergence of cloud computing many companies are looking at taking their Server services and data stores off-site. Net-Gen have take companies through this process, some with great sucess and some not so great. There is a balance to be found and it is based on many complex and interrelated factors. We have learnt to carry out in depth systems and needs analysis before any proposed migration so that the 'pros and cons' are well understood by any client, so that they may make a fully informed decision.
