Many companies that have shifted enterprise-technology tools into the cloud in recent years, in part as a cost-saving measure, say those investments have yet to pay off. Rather than run software and systems in their own hardware, commercial cloud users tap computing capabilities from providers such as Amazon.com Inc. and Microsoft Corp. They are also turning to multiple cloud providers, rather than relying on one cloud, for different systems and applications for different business areas. “Many first movers expected significant IT cost efficiency from their cloud investments,” said Barry Brunsman, a principal in KPMG’s CIO Advisory group. “You really do need to not just take it for granted that cloud is where you should head,” she said.
