When asking about that main barriers preventing organizations from moving to a cloud environment, most studies find that the top response is constant: security. A recent study conducted by the Uptime Institute was no different, showing that cloud security remains firmly in the bullseye of most organizations.
As CIO.com columnist Bernard Golden pointed out, the fact that the same concerns that have marked IT for at least the last five years and continue to arise in study after study shows that some companies are viewing those issues as borderline fixable. They resemble less of a issues to be addressed for such hesitant companies and more of an "immovable barrier" to any progress in cloud adoption.
"They want a final and definitive 'the cloud is now safe' pronouncement from someone - that is someone with sufficient authority so that the responsibility for any subsequent problems with a cloud application do not fall on the individual," Golden wrote.
Despite the seemingly insurmountable nature of addressing cloud security, more companies do continue to move to the cloud, both public and private. The study from the Uptime Institute indicates that in 12 months, both types of environment had seen greater deployment. Public cloud use improved by more than 50 percent, jumping from 16 percent of companies to 25 percent. Private cloud adopters increased 14 percent since 2011, with just 1 percent to go before reaching half of the market.
The next three years also look to be big for the technology, with 35 percent of companies planning to move workloads into the cloud to handle increased demands for capacity. That number falls just short of the percent of companies considering a move to the private cloud in general, with 37 percent possibly looking at it as a solution to reduce costs and improve scalability.
However, security concerns continued to dominate the conversation when companies looked for a reason to stare at the cloud from afar and not venture any closer. Sixty-four percent cited cloud computing data security as a reason not to adopt. The next biggest was compliance issues, garnering just 27 percent of the votes. Cost (24 percent), reliability issues (21 percent) and a lack of management expertise (20 percent) were next on the list.
Golden hopes that despite these concerns, the benefits will eventually reign supreme and companies will sprint past the "immovable barriers" to adoption.
"At some point, it will be obvious that cloud deployment is the customary method of deployment," Golden wrote, "and security will move to a checklist item in the project plan rather than a driver controlling the overall decision."
