Hi Dag

Makes a lot of sense, thanks for that.

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.
