G-Cloud changes focus of datacentre rollback

In a shift of focus, G-Cloud leaders are looking to datacentre cost-cutting over consolidation to save money, according to deputy government chief information officer Bill McCluggage.

In the past, the G-Cloud strategy called for reducing the number of government datacentres from around 200 to around 12, but this is no longer the main aim, McCluggage told the Cloud Computing World Forum on Tuesday.

He said facility closures will still happen, but other initiatives are being considered to reach the goal of cutting datacentre costs by 35 percent over five years, as laid down in the government's IT strategy paper in March. "We've seen a lot of talk about getting rid of datacentres, [but] it's a very blunt figure," McCluggage told delegates at the London event.

McCluggage then outlined the many ways of measuring the expense of a datacentre. "Is it the price of computing, the power usage effectiveness, the energy cost, whether it's highly virtualised — what do you measure as your key criteria?" he asked.

"If it's just about planting pins in real estate, I don't think we've got it right. This is about reducing the cost of datacentres," McCluggage said.

G-Cloud leaders are now concentrating on the 35-percent cost reduction target, rather than the datacentre number target, as their priority, he confirmed to ZDNet UK at the event. To do this, they are looking at a range of ways to cut expenses over five years.

If it's just about planting pins in real estate, I don't think we've got it right. This is about reducing the cost of datacentres.

In his speech, McCluggage compared cloud computing to a nascent utility. He noted that "the terms of travel are towards IT being a commodity, a utility. If that's where you're going... then it's more about focusing on the cost, not on the numbers".

"Cloud is about... taking processing power and storage and not being locked in terms of volume throughput and not having to make substantial investment," he said.

Government datacentres are only using around seven percent of their total IT capacity, McCluggage said, noting the government hopes to move this figure to 70 percent by consolidating them.
