Large IT departments are losing control of cloud strategies as cloud services become more mature in the market, according to research from Capgemini.

Capgemini questioned 460 IT leaders and senior business managers at large companies worldwide who employed over 10,000 staff, and found that almost half (45%) of organisations now had individual business units with responsibility for cloud strategies.

"The initiative for driving cloud solutions is shifting from the IT department to the business unit as companies focus more on tangible business value," said Ron Tolido, Capgemini senior vice president and chief technology officer of applications for continental Europe.

"The cloud has rapidly established a new benchmark in terms of how easy, quick and flexible solutions should be available to the business, and it puts the alignment between business and IT in a whole new perspective."

From the UK sample of those surveyed, 83% of UK firms, compared with 76% of total organisations surveyed, have decided on a strategy for adopting cloud computing. The main blocks for a move into the cloud in the UK are said to be legal issues (40%) and HR factors (27%).

Also, 38% of UK firms cite the board as a driver for the move to the cloud, while 16% say the board is a blocker. The top two industry events or triggers that will cause organisations to opt for the cloud are "emerging markets and territories" (53%) and "a new application" (23%).

The major impediments preventing a greater uptake of the cloud in UK companies include "lack of integration" (45%), "lack of agility in the business" (35%), "issues with data sovereignty" (33%), "fear of security breaches" (33%) and "lack of a clear cloud strategy" (31%).

There is also more confidence in the UK about putting data into the cloud, with 82% of UK companies agreeing that "they trust placing data in the cloud" - far higher than the 56% worldwide.

On average, across all companies in the survey, there is an expected 25% increase in investment in the cloud planned for next year, with the UK looking to increase investment above the average with a 30% increase.
