Subject Re: Network architecture question

You can do bonded nics in basic zone. The limitation with basic zone is
that the Vms cannot have multiple nics. Did you need multiple nics for
your vms?
If you need advanced network services such as static NAT and load
balancing, advanced networking is probably your best bet (currently,
unless you want to invest in a Netscaler for these services).

Not sure that VXLAN will solve your problems since that has scaling
problems as well. On vSphere an NX1000v DVS can only handle about 64
hypervisors IIRC.
