Security vendor CloudPassage has released results from a survey of 200 IT professionals regarding their use of public cloud resources for business-critical apps. It turns out that 4 out of 5 companies are using some sort of cloud infrastructure, whether it\u2019s public, hybrid or private.\u00a0\tHere are some nuggets sent to me by friend and CloudPassage Chief Evangelist Andrew Hay:\t\t\t70 percent more people are planning to use public cloud environments for temporary workload\/big data in 2013 as compared to 2012\t\t\t42 percent of those in the public cloud use cloud servers for external applications\t\t\tPublic cloud hosting is also being used for the deployment of internal applications -- 36 percent report using it for HR, CRM, ERP and the like\t\t\tCloud security concerns are fading. This year, just 23 percent said they\u2019re concerned about the lack of perimeter defenses and network controls in the public cloud.\tMany of the respondents have big plans for public cloud deployments, and big data and media are the prime motivators. Seventy percent more people plan to use public cloud environments for temporary workload\/big data in 2013 as compared to this past year. They also plan to increase their use of cloud-based media hosting and internal development and testing in 2013 by 31 percent and 29 percent, respectively.\tAccording to the press release Hay sent me, "Increased adoption of public cloud can be attributed, at least in part, to the fact that specific security concerns are beginning to fade. This year, just 23 percent of respondents said they are concerned about the lack of perimeter defenses and network controls in the public cloud. Only eight percent voiced fear about providers having access to their guest servers, whereas 20 percent are worried about the multi-tenancy of the public cloud."\tI'm glad to see companies diving in. The question that remains to be answered is if they will handle it in a way that minimizes the potential for security breaches. Time will tell.
