Virtualization is now a road tested technology which has demonstrated its reliability and applicability to businesses of all sizes. Virtualization allows for multiple operating systems to be run at the same time on the same server. You no longer need to have dedicated servers running specific applications, and the dependency between hardware and software is broken, allowing you to deploy systems and applications much faster, and with much less cost.
The major benefits of virtualization include:
This applies to both capital and continuing operating costs, which are both greatly reduced. Software and applications no longer require you to provision specific brands or models of hardware, allowing you greater flexibility in how you select and use your servers. In addition, you require fewer servers because you can now run those same applications and systems on the same servers, without creating conflicts or requiring that they all must run on the same operating system. Reduced numbers of servers means reduced costs to operate them, and less heat is generated as a result too plus there is a reduced maintenance cost.
Because you can create or move your virtual environments at will, usually setting them up in minutes, you create much greater resilience in your setup. If a server goes down, simply failover to a virtual machine on another server, hosted in your own datacenter or someone else’s. If the issue is simply that the virtual machine itself has failed, setup another almost instantly and move the application over to that. Even better, have virtual machines already setup and ready to go in the event of a failure, so you can failover to the new virtual machine in seconds or faster, indeed so fast your users may not even notice.
Enhanced IT Performance and Agility
IT itself can improve its own performance, by delivering projects and deployments much faster. As virtual machines can be created almost at will, if an environment is required, then provisioning is so much faster (and cheaper as there is no new server to buy and physically provision).
If you move your systems and applications to a virtual environment, wherever that may be physically located, your access to that environment can be from anywhere you choose. If you need access to your physical infrastructure, then you may want to build an in-house datacenter, or have it managed by a third-party, however wherever the physical servers reside, you can bring all of your management and team resources into one central location and have them access the virtual environment over the Internet ensuring that decision makers and those who execute are all in the same spot.
Improves Disaster Recovery & Business Continuity
Again, as setting up new virtual servers is a matter of a few mouse clicks, and these machines can reside anywhere (even in multiple locations) you automatically improve DR and continuity. Making backups is easier and more effective too, and in the event of an event, failing over from one virtual machine to another, wherever it may be located is simple, fast and highly effective at keeping your people and business working.
