Dag
Just a quick follow up on this.
I haven't tried security groups with advanced networking so tried to set up
yesterday but had issues adding host.
For normal advanced network (no security groups) I configure the NIC for VM
traffic (and public) without an IP and set the switch port to be a trunk and
then ACS just creates the subinterfaces internally when I add networks.
With advanced and security groups I assume I do the same for the guest VM
traffic NIC (no public) and just configure it as a trunk as there will be
multiple vlans on it ?
So no IP address assigned to that NIC, correct ?

Hi Jon,
In short you are right – advanced networking offers a lot more features, and
the only benefit of basic networking is a simpler setup (no VRs) as well as to
a certain degree more scalability since you can run relatively large L3
networks (with the proviso that broadcast traffic may be a limiting factor). As
security groups rely on access to underlying networking on the hypervisor they
will also most likely never work on VMware due to the proprietary nature of
ESXi.
If you look through the user@ / dev@ mailing list you’ll see we have started
discussions around deprecating basic networks for advanced zone with security
groups – since the latter offers the same networking functionality as basic
(security groups, no VRs) but offers the scalability of running multiple of
these basic type networks (a traditional basic zone can only run one network).
So all in all if you are looking at longer term strategy whilst wanting the
simplicity of basic networking you should look at this option (looks like you
might have played with this already).

Having looked at both in a lab environment I am wondering what the
advantages of running basic networking are.
Obviously with basic you can use security groups (although you can with
advanced if using KVM) but apart from that advanced seems to offer all the
features of basic plus a whole lot more.
The only downside I have found with advanced is that VRs seems to be the
most "flaky" aspect of ACS and obviously you end up with a whole lot more of
them.
Would be interested to hear opinions either way.
Thanks
