Subject RE: [PROPOSAL] "Internal Load Balancing between VPC tiers"
Date Tue, 26 Mar 2013 02:45:41 GMT
If the services are provided by a LBVM, it should have access to both networks, one NIC in
the web tier (the guest network where the VIP is present) and one NIC in the App Tier (the
guest network where the server vms are present), would that understanding be right? So when
provisioning the LB VM the user has to specify these 2 networks?

On the similar lines, if an external LB Appliance is providing the service,  it has to be
wired to both the VIP network  and the server vm network.
