Always On Bronze (single active location - cloud region or on prem data center)¶

The Always On Bronze architecture includes the following:

Two BDR data nodes
One BDR witness node that doesn’t hold data but is used for consensus
Two HARP-Proxy nodes for routing application traffic to the “lead” master
One barman node for backup and recovery can be onsite or offsite

BDR and HARP-Proxy nodes should be spread across availability zones.
