You’d think that the 2nd or 3rd player in Virtualisation / underlying cloud computing technology would be doing better in getting “press” about the value of its virtualisation performance & capabilities. So in this context, Citrix’ Xen Virtualisation is a “silent winner” still in 2011.
The challenge for Citrix is to keep innovating & push the boundaries on Virtualisation capabilities and performance from newer hardware & better methodologies for 2012 & beyond!
From our side, we prefer to use Xen based virtualisation technologies for customer VPS/VDS services. VMWare still isn’t on desired or required to service our customers and the other virtualisation technologies aren’t desirable due to their poor QoS provided to virtualised customer servers.
