Too often, organisations aren't getting as much out of virtualisation and hybrid cloud computing as they first thought they would, according to a Symantec survey of 3,700 information technology managers in 35 countries that was published today.
About a quarter of the survey's respondents said their organisations have already implemented some form of storage virtualisation, desktop/endpoint virtualisation, server virtualisation, private storage as a service, or private/hybrid cloud computing. Another quarter are in the midst of implementing, 20 percent are in pilot projects, and about 20 percent are discussing or planning for it. But of the quarter of IT managers who did implement, many expressed disappointment that the expectations of the benefits in operational costs and performance didn't match up to reality.
While most seemed largely satisfied with server virtualisation, 33 percent were disappointed in storage virtualisation, 26 percent in desktop/endpoint virtualisation, 37 percent in private storage as a service and 32 percent in private or hybrid cloud computing.
The biggest complaints about hybrid/private cloud computing were in scalability, security and time to provision new resources. In storage virtualisation, about a third of IT managers felt they were getting anticipated benefits in operational expense, agility or scalability. And more than a third were disappointed in terms of their expectations about scalability, reduced complexity and efficiency in private storage-as-a-service.
The scalability has to do with managing the virtual environment, said Sean Dennington, director of Symantec's information management group cloud strategy. Overall, many of the survey respondents active in implementing virtualisation and cloud computing were finding it "not operating as well as it could be," Dennington said.
Dennington said one reason for the gap between expectations and reality, especially in storage virtualisation, is that it changes the dynamic of the data center and impacts storage, server and database administrators. Another finding of the survey is that virtualised environments did raise complaints about performance, with 72 percent of respondents saying it did impact performance and application availability.
Dennington said few called this a barrier to using virtualisation, but there's concern because increasingly mission-critical applications, including enterprise-resource planning and e-commerce, are being deployed in virtualised environments.
The Symantec survey did not ask which specific virtualisation platform or services were being used.
