Cluster instances in different regions

While you can technically cluster together two geographically distant instances, we don't necessarily recommend it in all cases. Since there's a fair bit of distance between each node, if you're trying to active-active cluster them using a load balancer, there will be delay between one node updating the other node when changes are made to an assignment, for example. Depending on your use case/the logic in your workflows, this latency can cause problems like assignments or process data getting out of sync.
