American cloud companies stand to lose billions of dollars in business because of Edward Snowden's NSA revelations, and non-U.S. companies are already preparing to pick up the slack. "The leading cloud companies have been U.S.-based companies, but now there's a real reason to invest in these types of companies that are not in the U.S.," said James Staten, an analyst at Forrester. The fear that the U.S. government can pry into companies' systems at will and access sensitive data is causing a growing number of businesses to either avoid big U.S. cloud providers--which include IBM, Hewlett-Packard and Oracle--or abandon the cloud altogether.

So far, growth in cloud computing has largely been domestic, but part of the problem for the U.S. is that the next big growth opportunity is the international market. "We are sidelined at the most important part of the game. Even if we resolve this issue in the next 12 months, we've had two years where we've been sidelined. That's permanent damage and not something you get back," Castro said.

Forrester Research says the damage could reach as much as $180 billion by then if companies' spying concerns continue to outweigh their desire to go cloud. IBM, Oracle and HP did not respond to email requests for comment. So, who's likely to grab that business? International providers including NTT Communications, a Japanese telecom company; Fujitsu, a Japanese information technology service provider and Telstra, Australia's largest telecom company, are positioning themselves to be global leaders in the industry, Staten said. There's also been a significant boost in the number of cloud-specific companies coming out of Israel and New Zealand since the Snowden leaks, Staten said. And although it can't be concluded that these companies were formed because of the Snowden revelations, it's certain that the spying revelations are helping put these firms on the global map, Staten said.
