In basic zone you do get load balancing functionality but current implementation works only with NetScaler. At some point in 2.x there was ELB VM's providing load balancing in basic zone but its not supported (actually not enabled, whole code exists in CloudStack some one needs to test and re-enable it) lately. Advanced zone networking model provides lots of rich networking features with native virtual router appliance. Any particular reason you choose 'basic network' model? If you have option you might want to consider using advanced zone deployment. > >It would also be nice to have the System VMs and routers be redundant so >that if a host fails it will automatically fail over to the other host >with as little down time as possible. Again I see lots of talk about >this but nothing to show how to do it. For virtual router, you have redundant virtual router which can be enabled in the network offering.
