» Consul Enterprise Redundancy Zones
Consul Enterprise redundancy zones make it possible to have more servers than availability zones. For example, in an environment with three availability zones it's now possible to run one voter and one non-voter in each availability zone, for a total of six servers. If an availability zone is completely lost, only one voter will be lost, so the cluster remains available. If a voter is lost in an availability zone, Autopilot will promote the non-voter to voter automatically, putting the hot standby server into service quickly.
