Replication Pair (RP) is a basic ARO concept. It is a primary-secondary pair of regions used for asynchronous replication. A single primary region can have multiple RPs. However, each RP has a dedicated AROVA instance running on the primary or secondary region. The following figure illustrates the RP concept. All such AROVA instances will be on the same Marketplace user subscription.
