Re: Mid Tier - Load Balancers
Here is what we do… (We have 2 cName aliases 1 for MT arsweb and 1 for ARS prodars that are load balanced) The LB points a user to one of our MT servers which connects to the ARS on the same box. We added to that server's /etc/hosts file so that the cName for the MT points to the MT on that server. We did the same for the cName of ARS. This way once a user is on a prod box they stay on that server (any reference to the MT load balanced cName goes to the MT on that same server, any reference to the ARS load balanced cName goes to the ARS on that same server) Each MT server is configured to know the load balanced ARS cName and the local server name only. Each ARS server knows itself by both the local name and the load balanced cName. It may not be the best method of doing this but it works.
