One big decision you need to make in this scenario is whether you want true synchronous replication or if asynchronous replication possibly with some time-bound is acceptable. For the former, each byte must traverse the network before it is acknowledged to the client; for the latter, data is written locally and then transmitted shortly after that. Synchronous replication obviously imposes a much larger performance hit, but asychronous replication means you may lose data over some recent period (but the data will always be consistent).
