"Server virtualisation projects were most successful, with only a nine percent average gap between expected and realised goals," said Tan. "The biggest gaps occurred in server manageability, reducing capital expenditures and scalability. The average shortfall in storage virtualisation was 17 percent, with disappointments coming in scalability, reducing capital expenditures, and storage performance."
Respondents also reported an average gap between expected and realised goals of 13 per cent with endpoint/desktop virtualisation, citing disappointments in virtual desktop support, new endpoint deployment, and reducing helpdesk calls and/or costs, he said.
"In addition, private storage-as-a-service projects are challenging to implement and fall short of expectations by 25 percent," said Tan. "For example, improving computing availability was a goal for 100 per cent of respondents, but reached by only 50 per cent.
"These gaps are a hallmark of early stage markets where expectations are out of step with reality," he said. "As the virtualisation and cloud markets continue to mature, we expect to see those gaps close."
Focus on collaboration
"Organisations investing in virtualisation and hybrid/private cloud technologies tend to follow a similar path, starting by virtualising less critical applications such as test and development environments and progressing to more important applications such as e-mail and collaboration; line of business; e-commerce and supply chain; and enterprise resource planning (ERP)/customer relationship management (CRM)," said Tan.
"However, the survey shows that organisations are leveraging virtualisation for business-critical applications," he said. "Of enterprises which are implementing virtualisation, 70 percent plan to virtualise database applications in the next 12 months. Fifty-two percent plan to virtualise Web applications, and 35 percent plan to virtualise e-mail and calendar applications. Thirteen percent plan to virtualise ERP applications."
"In addition, as virtualisation and private cloud technologies become more widely adopted, the cost and performance of storage is becoming increasingly top of mind," said Tan. "Forty-seven percent said storage costs somewhat or significantly increased with server virtualisation. Of those in the process of virtualising storage, the top three reasons for deployment (89 per cent respectively) include improving overall agility, improving storage performance, and reducing capital expense."
"It's apparent that virtualisation and cloud computing are quickly becoming indispensable tools for IT," he said. "At this point, it's largely a matter of when, rather than if, an organisation will adopt these technologies."
