Ceph RADOS Gateway multi-site replication¶
Ceph RADOS Gateway (RGW) native replication between ceph-radosgw applications is supported both within a single Juju model and between separate models. When using multiple models, Juju cross-model relations are leveraged.
Typically, each ceph-radosgw deployment is associated with a distinct Ceph cluster in different physical locations, in which case separate models will be used.
Multi-site can either be set up at the initial deploy time of both clusters or added on to a pre-existing cluster.
In the event that the primary site has an outage, it can be failed over to the secondary site.
Finally, scaling down multi-site to single site is supported.
Deployment and configuration details are available in the Charmed Ceph documentation.
