NSA revelations costing U.S. cloud-computing providers

|By:, SA News Editor

U.S. cloud-computing companies could miss out on $21.5-35B of revenues over the next three years because of concerns about how U.S. authorities such as the National Security Agency have been accessing the firms' user data.

The estimate comes from the Information Technology & Innovation Foundation think tank.

Companies that could be affected include Amazon (AMZN), Google (GOOG) and Microsoft (MSFT).

There's increasing evidence that non-U.S. firms have been canceling orders and limiting their use of U.S. cloud service providers. In a membership survey by the Cloud Security Alliance, 10% of non-U.S. respondents said they had ended a project with a U.S. cloud company, while over half said they would be less likely to use one.
