Nationwide Building Society has reduced its costs by £8m after virtualising 500 servers.
The financial services company is working with Unisys on a datacentre upgrade that will take a few years. Sever virtualisation allows multiple servers to run on a single hardware unit, saving money on energy bills and reducing hardware requirements.
The company has virtualised an average of 12 servers onto each physical machine. At the current rate of virtualisation, it will end up with 42 physical servers doing the same volume of work previously done by 500 servers.
"This reduction has not only saved space within the datacentre but has also significantly contributed to a decreased carbon footprint through a reduction in power and air-conditioning usage," said Nationwide.
