Symantec recently announced the findings of its 2011 Virtualization and Evolution to the Cloud Survey which examined how organizations plan to move business-critical initiatives to virtual and hybrid cloud computing environments.
The survey highlighted topics including server, client, and storage virtualization, storage-as-a-service, and hybrid/private cloud technologies; and the results uncover disparities between expectations and reality as enterprises deploy these solutions. The survey is based on more than 3,700 respondents from 35 countries worldwide.
Adoption of server virtualization is widespread, and more than 75 percent of organizations are discussing private and hybrid cloud deployments. Of the technologies evaluated in the survey, server and storage virtualization are the most mature with 45 and 43 percent of enterprises implementing. Private Storage-as-a-Service is the least mature with 36 percent adopting.
Early investments have revealed gaps between expectations and reality which indicate that organizations are still learning what these technologies are capable of and how to overcome the new challenges they bring with them.
Server virtualization projects were most successful, with only a 4 percent average gap between expected and realized goals. The biggest gaps occurred in scalability, reducing capital expenditures and reducing operating expenditures.
The average shortfall in storage virtualization was 33 percent, with disappointments coming in agility, scalability and reducing operating expenditures.
Respondents reported an average gap between expected and realized goals of 26 percent with endpoint/desktop virtualization. They cited disappointments in new endpoint deployment, application delivery and application compatibility.
Seventy-seven percent of organizations are considering private Storage-as-a-Service, but these projects are challenging to implement and fall short of expectations by 37 percent. For example, complexity reduction was a goal for 84 percent of respondents, but reached by only 44 percent.
The survey shows that organizations are leveraging virtualization for business-critical applications. Of enterprises who are implementing virtualization, more than half (59 percent) plan to virtualize database applications in the next 12 months.
Fifty-five percent plan to virtualize web applications, and 47 percent plan to virtualize email and calendar applications. Forty-one percent plan to virtualize ERP applications.
More than half of respondents (56 percent) said storage costs somewhat or significantly increased with server virtualization. Of those in the process of virtualizing storage, the top three reasons for deployment include reducing operating expenses (55 percent), improving storage performance (54 percent), and improving disaster recovery readiness (53 percent).
Seventy-six percent of enterprises who have implemented server virtualization indicated that security was a somewhat/extremely large factor in keeping various constituents from being more confident about placing business-critical applications on virtualized servers. Sixty-three percent listed security as a significant/extreme challenge to implementing server virtualization.
