Hi Dag, Thanks for the reply. I am trying to use Shapeblue CCS (Container as a Service) with ACS, but for that Isolated networks are required which are only available in Advanced Zone. Further, I want to explore Cloudstack further and am also aiming to test and configure other advanced features such as load balancing and auto scaling without netscaler device. For that I badly need Advanced Zone networking (especially isolated networks offerings). I just want to know if Advanced Zone can succesfully function with two networks, one physcial NIC and no VLAN tagging.
