Multi-site and multi-cluster
There are two sets of features allowing connections and operations to be performed on different clusters in the same data center (multi-cluster), or on different locations (multi-site). Here is the general distinction between the two:
Multi-cluster covers closely packed clusters (pods or racks) with a fast and low-latency connection between them.
Multi-site covers clusters in separate locations connected through an insecure and/or high-latency connection.
