SEC 340 – Virtualization Memo

You are the CIO of a medium size company tasked with modernizing the current operating environment. Create a persuasive memo to the board in favor of adopting virtualization as a cost-effective way to upgrade the aging network.


Hello Board of Evil Mutants,


Currently our older hardware isn’t up to the job of running the operating systems and applications we want, at the speeds we want. They are vulnerable to parts of the machines failing which can result in unnecessary down time to recover files or migrate servers. The energy costs for many separate machines is also greater than it has to be.

If we move to virtualization, we can overcome these problems. Virtualization means that we can create an instance of an operating system – a single file represents each virtual server – that is run by something called a hypervisor. That hypervisor can be run on upgraded physical hardware. We could run all of our servers virtually on one piece of physical hardware, though we might want a backup just in case. If the power supply burns out or the memory goes bad, we can quickly move the instances of the servers to another hypervisor on another physical server without having to reinstall anything. That process can take place very quickly.

Additionally, if we wish to expand and add servers, it easy to do so as long as we have available CPU and RAM resources free to run them. We wouldn’t have to purchase or set up a new piece of hardware every time we get the idea for a new server we’d like to run like cacti or solar winds, or even a new ticketing system. We could simply set up a new instance the same way we would on physical hardware, but virtually, avoiding all the extra hassle of setting up another computer, finding space for it, connecting it to the network, setting up an uninterruptible power supply, and so on. Also, if we do need to upgrade to a newer version of a server, it’s easy to leave the old one running in case there is some functionality or resource that is not availability in the new version.

There would be a central manager for these servers – one place to go to login to any server of your choosing through one interface, rather than having to remember multiple different ip addresses or sets of login information. If needed, we could set up these instanced servers remotely for redundancy and availability reasons

Having only a few physical servers to run multiple virtual servers can save a lot of time, money, and space, and is definitely the way to go moving forward.
