Migrating things > to container and making them ready for high availability is highly "simply not possible" as i said. to do it you need to HA across local nodes (things with very low round trip time) because now everything you do has to become a syncrhonous transaction across 2 or more hosts. if one host is e.org and another is in some other datacenter we'll be paying for it in performance all day every day in every commit or phab interaction etc. if you don't do this and run async then you have conflict resolution issues to solve. and then the extra hosting has to be set up, configured, managed and paid for... > time consuming.
