Please take a look at http://s.apache.org/k8w Slides 32-39 explain the networking layout in security groups in basic networking. The VR (one per pod) simply dispenses DHCP and user data. It is not a firewall. The firewall is implemented at the hypervisor level. This is what allows it to scale O

Justin, As Chiradeep mentioned, 'basic zone' is solution you should be trying out. With basic zone, you could associate guest subnet per pod, there is no VLAN's required in the zone. Your L2 broadcast domain is restricted to POD. POD becomes unit of scale in basic zone, so east-west traffic acros

I looked at Security groups and I am not sure how this solves my problems. Sure it provides guest isolation but that is through the virtual router correct? The underlying physical network --outside of cloudstack-- is still layer 2? That is what I am concerned with. When defining what IPs my gues

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

We have 2 pairs of bonded 10g nics on each box. Wouldn't that require an advanced network? Is it possible to do the security groups with small L2 networks in advanced networking? Justin Sent from my iPhone On Apr 9, 2013, at 12:38 AM, Chiradeep Vittal wrote: > Have you considered using a b

Have you considered using a basic zone? With security groups you can have *lots* (thousands of) with very small L2 networks. On 4/8/13 10:28 PM, "Justin Grudzien" wrote: >My team has been working for three weeks with CloudStack architecture >design and we are struggling to put together a network
