New Tutorial: 2 DCs with Axxana Is Better Than 3 DCs

To ensure continuous application availability in the event of a disaster, organizations operating mission-critical databases typically implement solutions that revolve around synchronous replication in a three-data-center topology; however, these solutions come at a high price in terms of dollars and risk. That’s because three-data-center solutions cannot guarantee zero data loss and therefore continuous availability in the event of a rolling or regional disaster. In addition, maintaining a nearby data center to host the synchronous replication instance imposes significant Capex and Opex costs, as well as the costs associated with using fiber optic lines to connect the primary data center and the nearby facility.
