There are various reasons that virtual machines/servers may be deployed within a datacenter. Some of the 'main' reasons are isolation of applications (to prevent conflicts), consolidation (for easier management of less hardware), ease of testing (due to taking system snapshots/rollbacks/etc), and migration (allowing virtual machines and their apps to be moved to other hardware relatively easily).
We do believe that virtualization of a stand-alone CBN installation can benefit an organization. However, in practice, we believe that virtualization of a live CBN ASP system is likely to be counterproductive.
1) CBN ASP is architected to separate user account processing as much as possible; thus there is little chance of one account impacting another.
Hence, isolation is taken care of within CBN.
2) CBN ASP shouldhave priority access particularly with respect to network and disk I/O, with CPU load a little way behind. Due to the typical nature of usage and load, it is unlikely that a single server could sensibly be used for other operations without potentially jeopardizing the system availability.
3) CBN ASP is licensed for a maximum number of cameras on one server; thus, running multiple servers requires multiple licenses, which is likely to be less cost effective. Also, some virtualization technologies do not present a consistent hardware description on subsequent boots, which would prevent the license protection from working (hence disabling the software).
