Performance issues are a factor for the majority of organizations, as well. Seventy-six percent of those who have implemented server virtualization stated that performance was a somewhat/extremely large factor in keeping various constituents from being more confident about placing business-critical applications on virtualized servers. Seventy-two percent of organizations that have implemented hybrid/private clouds cited performance as a significant/extreme challenge.
Among enterprises that have implemented server virtualizations, reliability was the No. 1 concern: 78 percent said it was a somewhat/extremely large factor in keeping various constituents from being more confident about placing mission-critical applications on virtualized servers. Of those who have implemented storage virtualization, 83 percent stated uptime and availability as an important goal.
According to the survey findings, 46 percent of CFOs who are implementing hybrid/private clouds are less than somewhat open to moving business-critical applications into those environments. Forty-four percent of CEOs are cautious about moving these applications.
Main concerns cited about virtualization and hybrid cloud deployments are reliability (78 percent), security (76 percent), and performance (76 percent).
In practice, many C-level concerns are unfounded based on responses from IT. For example, concerns about performance are a top reason cited for caution, yet 78 percent to 85 percent of those who deployed server virtualization achieved their goals related to performance.
Enterprise ITs evolution to the cloud has its fair share of challenges, but also compelling rewards. Despite concerns, most enterprises are implementing virtualization and moving to a cloud computing future. For these enterprises, Symantec offers recommendations to help make the journey as smooth as possible.
Symantecs 2011Virtualization and Evolution to the Cloud Survey is the result of research conducted in April 2011 by Applied Research, which surveyed IT and C-level professionals responsible for computers, networks and technology resources at small, medium, and large enterprises (defined as 1,000-2,400, 2,500-4,999, and 5,000+ employees). The report was designed to gauge how organizations plan to move mission-critical initiatives to virtual and hybrid cloud computing environments. The survey included more than 3,700 respondents from 35 countries in North America, EMEA (Europe, Middle East and Africa), Asia Pacific and Latin America.
