The growth of government backed cloud schemes, such as the one unveiled at the start of this week, could run into trouble because of differing data regulations.

The UK government's decision to launch the G-Cloud to procure products and services is something that is expected to be replicated elsewhere. But because of different approaches to data laws across the world, and across the EU in particular, the chances are that there will be a clash of policies somewhere down the line.
A study into countries' cloud positions has been undertaken by the Business Software Alliance, with the findings showing a sharp contrast between those mature markets that are cloud ready and those that are nowhere near the mark.
The UK ranks seventh out of 24 countries in the BSA global cloud scorecard behind Japan, Australia, Germany, the US, France and Italy.
"The true benefits of cloud computing come with scale," said BSA President and CEO Robert Holleyman. "In a global economy, you should be able to get the technology you need for personal or business use from servers located anywhere in the world. But that requires laws and regulations that let data flow easily across borders."
"Right now, too many countries have too many different rules standing in the way of the kind of trade in digital services we really need," he added.
