Banking giant Credit Suisse has found a way to stem its seemingly ever-growing need for electricity, through the use of virtualisation. The use of the technology was a necessary one, noted John Froud, Credit Suisse's director of information technology and head of technical architecture, speaking at the Optimising Cloud Computing Seminar.
"We were running out of data centre space," he told the audience. As a result of virtualising many of its servers: "We've been able to aggressively address our power uptake consumption," he said. Around three years ago, the company started adopting virtualisation, along with a round of server consolidation, as a way of avoiding building another data centre or expanding the existing ones. In years past, the company's data centres' collective energy use would increase by 600 kilowatts per year, Froud said. Since adopting virtualisation, the company has since cut this number to an annual increase of 200 kilowatts per year. About 25 percent of the servers Credit Suisse runs are virtual ones.
