A recent survey regarding business use of IaaS has found companies worry less about security once they deploy cloud services.

The survey, which included 400 businesses and was conducted by the Yankee Group, found the major barrier inhibiting companies from adopting IaaS was security. However, companies that have already introduced an IaaS solution ranked five other issues they felt were more important than security, showing that initial concerns about the technology disintegrate after deployment.

Sandra Palumbo, a research fellow at the Yankee Group, said the pre-implementation concerns stem from a lack of understanding of how the cloud works.

“Some of that is companies not fully understanding what the cloud is, and once a business starts trying it out and using it, they see that security issues aren’t as great as they’re made out to be,” she said.

The survey found 24 percent of large enterprises with cloud experience currently use IaaS, with an additional 37 percent expected to adopt the cloud-based solution during the next two years.

System integrators continue to be helpful advisers and guides for companies interested in the cloud. Twenty-nine percent of surveyed businesses said system integrators were the most trusted suppliers of cloud computing.

Integration experts have become a helpful resource for organizations. With many business leaders still misinformed and unaware of how the cloud works, system integrators can provide company executives with the information they need to move forward with a cloud computing strategy.

Storage and on-demand computing are two of the key areas of focus for IaaS use, according to the survey. Web-based storage solutions provide companies with additional security from onsite problems including document tampering, natural disasters and power surges.

“While adoption is still much slower than that of SaaS solutions, the market is gaining traction,” the survey reported. Palumbo said the market is still “evolving,” signaling that, as it becomes even more mature, its benefits will become even more prevalent.

A recent report from Companiesandmarkets.com found U.S. spending on IT products and services is expected to eclipse $629 billion by 2014. Spending on IT goods and services will have a compound annual growth rate of 6.5 percent for the next five years. The major driving force for increased IT spending will come from businesses’ focus on implementing cloud computing models, including SaaS and IaaS.ADNFCR-2553-ID-19930156-ADNFCR
