If you think you'll save money with cloud computing, think again

This article has been corrected to remove an error in the government’s cloud adoption timeline.

More than half of organizational users saved little or no money after transitioning to cloud computing, according to a new study, and only 14 percent actually downsized their information technology departments after moving to the cloud.

The findings could concern federal IT officials who have said they would save roughly $5 billion annually by transitioning about a quarter of the government's $80 billion annual IT budget to private, public and hybrid clouds.

About one-fourth of 3,500 public and private organizations recently surveyed reported no savings with cloud computing and about 35 percent saved less than $20,000, according to the study funded by CSC, a major government IT vendor, and conducted by TNS, a market research firm.

Respondents were in the United States, England, France, Germany, Brazil, Australia, Japan and Singapore.

Federal officials said the government's use of cloud computing wouldn't cost IT jobs because those staffers would be moved to jobs that supported other agency missions. Most savings, they said, would come from reduced spending on hardware, energy and real estate.

Computer clouds are essentially large banks of off-site computer servers that can pack data more tightly than traditional servers and move that data more nimbly as one customer surges in use and another declines. Cloud customers can access their data on any device, a major selling point for the cloud in consumer markets.

According to the CSC study, accessing data and programs on multiple devices was the most popular reason for corporate and public sector users to move to the cloud, accounting for about one-third of all transitions. Only 17 percent of those surveyed said they moved to the cloud to save money.

Nearly 95 percent of surveyed users said cloud computing improved the way they managed data while 80 percent said they saw improvements within six months of moving.

Surveys have routinely shown that concerns about security in the cloud are a major barrier for both federal and corporate IT workers.

    MIT Technology Review: Flash Storage As a Strategic IT Asset For the first time in decades, IT leaders now consider all-flash storage as a strategic IT asset. IT has become a new operating model that enables self-service with high performance, density and resiliency. It also offers the self-service agility of the public cloud combined with the security, performance, and cost-effectiveness of a private cloud. Download this MIT Technology Review paper to learn more about how all-flash storage is transforming the data center.
