We have a target cloud provider for a Zeebe cluster within a single region, but unfortunately we only have two availability zones available.
We have been aiming for an active-active configuration so that our cluster can maintain HA even if an AZ fails, however we aren’t sure whether Zeebe can support this configuration.
Based on the documentation a raft consensus protocol is used, which would normally mean that we would have to have an odd number of AZs (e.g. a3). Is that the case? or is Zeebe able to support a two-AZ configuration?
