So, we have a need for replication, but the existing push-only methodology doesn't work for us. I suppose our problems could be attributed to over- zealous network rules, but it is what it is. :) I'd love to change our network policy, but we aren't in charge of network policy, and there is no way I'm swaying the person that is.
Topology: 1) DMZ environments 1,...,n 2) An Internal network 3) A remote rack in a data center. Rules (by "talk" I mean initiate connections to): 1) DMZs can talk to each other, somewhat. 2) The Internal network can talk to the DMZs 3) The DMZ *cannot* connect to the Internal network 4) The remote rack of course cannot contact the Internal network, but can contact the DMZs. Scenario A, Master in a DMZ: - Slave in the Internal network could contact the DMZ master for replica setup, but the Master could not contact the slave to push updates - Slave in the remote rack could contact master in DMZ, but incoming to remote rack is very restrictive, so it is possible that master couldn't push. Scenario B: Master in the Internal network. - Slaves in DMZ and remote rack couldn't contact master for setup, although the master could contact the slaves to push updates. Scenario C: Master in remote rack - Not acceptable as remote rack is a testing rack, and may go down at any time. So, the best solution, from my current understanding is being able to somehow do pull-updates for replicas, because then we could have this: - Master in DMZs - Slaves in Internal network can contact Master in DMZ for replica setup and updates - Slaves in remote rack can contact Master in DMZ for replica setup and updates Any feedback is appreciated, especially if I'm missing something...obvious or minor. j -- Joshua J.
