But one of the major drawback we are seeing with DVR is the public IP
consumption.If we have 100 clients and 1 VM per client , eventually
there will be 100 tenants and 100 routers. Since its a public cloud, we
have to offer public IP for each VM. In DVR mode, fip name space in
compute will be consuming one public IP and if 100 VMs are running among
20 computes, then total 20 public IPs will be used among computes. And a
router SNAT name space will be created for each tenant router(Total
100) and each of it will be consuming 1 public IP and so total 100
public IPs will be consumed by central SNAT name spaces. So total 100 +
20 = 120 public IPs will be used by openstack components and 100 will
be used as floating IPs (1:1 NAT) by VMs. So we need 220 public IPs for
providing dedicated public IPs for 100 VMs !! Anything wrong with our
calculation?
Have you also looked at the namespaces created on the compute nodes and
the IP addresses they get?
Reading comprehension. I have heard of it... Re-reading I see that you
did. Clearly still to early in the day for me to avoid an Emily Litella
moment.
