Industry-specific clouds, also known as community clouds, are becoming more compelling because of cost advantages and expand-as-you-need flexibility. Unlike public clouds, community clouds are also better able to handle tough industry-specific security and compliance requirements.

According to Brian Bodor, a Washington, D.C.-based partner in Pillsbury’s global sourcing practice, community clouds are a hot topic among governments, particularly now that one of the biggest compliance-related issues has been removed from the equation.

Amazon's GovCloud and others have looked for ways to ensure that government data stays in the United States, Bodor said. This is good news for governments and agencies facing budget shortfalls and for whom capital investment is often trickier to budget than operating expenses.

“What makes the cloud attractive is that it's more a utility model,” Bodor concluded. “It has the potential to bring costs down dramatically.”
