Vertical Paxos algorithms use an auxiliary configuration master that facilitates agreement on reconfiguration. A special case of these algorithms leads to traditional primary-backup protocols. We show how primary-backup systems in current use can be viewed, and shown to be correct, as instances of Vertical Paxos algorithms.<\/p>\n<p>This paper came out of much discussion between Malkhi, Zhou, and myself about reconfiguration. Some day, what we did may result in a long paper about state-machine reconfiguration containing these results and others that have not yet been published.
