The government's G-Cloud deputy director Andy Tait has moved to VMware to head up the company's UK public services.

The appointment follows VMware's recent efforts to raise its profile in the sector, where Tait said VMware technology is used by "many public sector organisations" already.

Prior to his appointment at VMware, Tait worked at the Cabinet Office responsible for the applications store and data centre consolidation.

Former government CIO John Suffolk, with whom Tait worked, said last year that the government had more than 8,000 tier one data centres, and more than 220 data centres from other tiers. He believed that rationalising these would achieve savings of more than £500 million a year.

Analyst Georgina O'Toole at TechMarketView said in a blog post: "The move raises two questions: 'Is the UK government still serious about G-Cloud?' and 'what does it say about VMware's ambitions in the sector?"

O'Toole believes that the appointment of Tait confirms that VMware is serious about becoming a key player in the government's G-Cloud initiatives, but does not agree with commentators who see Tait's move as a sign of cloud computing losing traction with the government.

"Personally I can't see that being the case [that cloud computing is slowly losing prominence in the government's ICT strategy]," she said.

"Government organisations, just like commercial organisations, will slowly move certain elements of their ICT to the 'Cloud' as and when appropriate. Indeed it's already happening. The Government's Cloud Computing Strategy, due to be published in the next six months, will be critical to ensuring that the transition to the Cloud is handled consistently across the UK public sector."
