How RBS initiated a virtual desktop revolution

RBS teamed up with Fujitsu to roll out thousands of virtual desktops and it's not even finished yet.

The bank now runs much of the same hardware it was using three to four years ago. This doesn't just mean a lower cost, it meant RBS stopped using the classic desktop support model.

"What we've done is marginalise the desktop from being an intelligent device into being a kiosk, a dumb terminal," Diamond said.

"By making desktops thin we've effectively reduced support costs and at the same time introduced self-service for both migration and application provisioning."

There are always the luddites and the naysayers who say they don't want to change. They need to change to get the benefit back to the business.

When end users' hardware breaks, it can be simply replaced with a thin client device, meaning workers don't have to pester the IT department.

"What we're doing with that is driving the behavior of staff and changing the operating model for support. There's a huge benefit in that," Diamond said.

Changing the way the bank works

As for how RBS brought about the culture shift needed, the bank created a blue print for "Intelligent Working" to empower a new operating model and a new way of working.

"For too long the business had been given far too much power in decision making in technology and not fully embracing the fact they needed to adapt and change at the pace of technology," the IT head said.

"Our challenge was positioning this change so that the business leaders understood that if they got on board early, they would have financial benefits and they could leverage and improve staff engagement. The longer they delayed, the higher their costs would be, and more importantly they would risk getting left behind."

With the programme progressing well, senior executives within the business are now enthusiastically coming forward to adopt desktop virtualisation and acquire the tangible benefits early.

"There are always the luddites and the naysayers who say they don't want to change," he explained. "They need to change to get the benefit back to the business."

The state of play

RBS is still adding virtualised desktops, but there are areas it does not see Citrix virtualisation as appropriate yet. Whilst Deutsche Bank, Citrix Innovation Award winner at the vendor's Synergy 2011 event in Barcelona, decided to virtualise its trading floor, that's not something runner-up RBS is planning right now.

"We already have VDI type technology deployed in our trading room desktops, so expanding this programme to trading floors is not a priority today," Diamond said.

There aren't any plans to virtualise the remaining areas of the business either.

"There's approximately 20 per cent of the business where the cost of virtualising is high, and you just can't easily move users off a fat client," he added. "That's usually due to very bespoke legacy applications where the investment is too significant to move it into virtual. When we start to move away from some of those legacy applications when you move to automation with the evolution of new products then you can start to switch those off too."

In the UK, the bank will have 55,000 virtual desktops users up and running by the end of the first quarter next year. That is approximately half of the UK workforce. Virtualisaiton is effectively being used in every part of the business.

Looking forward, RBS won't have to spend 70 million again when it upgrades to Windows 8. It will be a much smaller figure, potentially less than 20 per cent of that, according to Diamond.

"It could be even cheaper," he added. "We'll be doing less than half a dozen core builds, with a simplified image deployment to our centralised VCS servers, instead of tens of thousands of desktops."
