Virtualization is a way of running multiple virtual operating systems on a single personal computer. It maximizes physical resources in a manner that sees the investment in your hardware is also maximized. You can have about sixteen virtual servers simultaneously running sixteen operating systems. You can exploit the computing power just by increasing the number of the logical systems a server hosts and this will help you save on money since you do not need to acquire additional servers to host its own operating system. The maintenance costs and repair costs will significantly reduce as well.
When is virtualization used?
Virtualization is perfect for applications mean t for small to medium scale usage. This means that it should not be used when there are high performance applications that require clustering of two or more servers together, to meet the required performance of a single application. A good service provider will ensure that the server does not exceed 50% of utilization even if it is at the peak, as this might reduce the overall performance of the systems.
Do you have to put all eggs in one basket?
The answer is certainly not. As the virtualization providers are charged with the task of ensuring that there is business continuity, they will ensure that single service does not reside only on a single server. There are various server types including FTP, HTTP, DHCP, DNS, RADIOUS, active directory services, File servers and many more. A good virtualization service provider should put all these virtual servers on more than two physical servers for redundancy purposes. It is easier for a provider to cluster the servers such that when one fails, there is always another server available to roll back to. When a single physical server becomes faulty, the virtual servers on another physical server will automatically pick the slack.
Who will handle the actual physical to virtual migration?
Almost any respectable virtualization company should offer a kind of physical to virtual migration tool. The tool picks the existing physical server and creates a virtual hard drive image of the physical server, using the necessary modification services so that the server can boot up and exactly run as a virtual server. You will not need to rebuild any of your existing servers or even manually reconfigure them, to have a successful virtualization plan.
How about patch management of virtualized servers?
You need a management system that should ensure your servers are patched with each virtual server on its own physical hard drive. Even if there will be considerable developments in future, a virtualization solution should come in handy when this need arises. You will then be able to patch the virtual operating systems just as you would other systems.
Are you looking out for the support?
Perhaps virtualization provider who is licensed to run the task should be your first concern. Again, you would not want to pay for every program that needs to be hosted in a drive. You can run a simple search online and get the best and reputable virtualization service provider that will see the process is successful. Remember to go through the various reviews left behind by satisfied customers about a particular provider.
