Virtualisation is ready to support mission-critical mainstream applications, but users still fear poor security and inferior performance under a hosted enviroment, a survey has found.
87% of the 360 users polled are currently not comfortable utilising a shared virtual environment. Only 13% of respondents are confidently willing to share a physical server with other hosting customers, a practice common in hosting, with top concerns stemming from performance and security vulnerabilities in shared environments.
"While users can allocate pre-defined processing power and memory, current technologies do not allow users to place a limit on the number of input and output devices which can consume large amounts of bandwidth across the network and bring servers in a shared environment down," said Nicolas Keller, director of platform products at Rackspace, which carried out the survey.
The survey also revealed that 57% of respondents are already using virtualisation for internal applications, and 72% of respondents are comfortable hosting mission-critical applications in a production environment on a virtualised platform internally.
