umber of servers in an enterprise increase with the growth of the organization. With slowdown effecting everyone, the first thing for an enterprise to use is their existing infrastructure as much as possible, be¬fore they plan to buy any new hardware. Since servers are rarely utilized to their maximum levels, this is where server virtualization can help. Server virtualization itself now doesn't need any introduction. Virtualization has grown so much over the past couple of years that, whenever deploying a new server, first thought is to deploy it as a VM.

Sever virtualization offers many benefits, as you are using your existing
server, you can easily save on the costs which you would have spent on new server. With existing server being utilized optimally, you also save on power, deploying a new server will consume more power, than using existing ones at optimum levels.



Another benefit of server virtualization is flexible resource allocation. in case you find that one of the servers in the virtual environment doesn't need so many resources, you can take them away and reallocate to another server that really needs them. This could be RAM, storage space, network interface or a number of other things. All this can happen dynamically without bringing down the physical server.

Server virtualization is also considered a green technology.As you won't be deploying new server, you will be reducing carbon emission to atmosphere. Consider these stats given by Microsoft on ';ts website "a server setup of Standalone liS x 10 results in 34,084 Kg of C02 and after server virtualization, a setup of One Hyper- V server with 10 IIS7 VMs results in only 3,491 kg of C02. That's a saving of30,593 kg of C02 emission into the atmosphere. Just in case you are curious about reductions you can achieve in terms of power, C02 and money, go to
