http://serverfault.com – I'm working on design of enviroment for enterprise application. There is plan to host application in one Hyper-V server in several VMs. Host server has limited CPU and memory capacity, disrtributed between VMs. Is it good idea to use load balancers in order to improve perfromance of VM servers hosted in Hyper-V enviroment or much better to allow to use more resources to VMs?
