Hi Swapnil, I do not think using HAProxy with AWS load balancer is a good approach.
According to the AWS load balancer architecture, IMO we may need to create a load balancer per cluster. The reason is that an AWS load balancer instance could only have one set of port mappings and one set of members. This maps to a cluster in Stratos. DNS based domain mappings can be used for handling hostnames. Thanks On Sat, May 23, 2015 at 9:56 PM, Swapnil Patil <swapnil.r...@gmail.com> wrote: > Hi Imesh, > > Thanks for the feedback. > > 1.
