- The DB is up & running on both nodes having usable complete resources
- Primary Node operates in RW mode and Secondary node resides in READ ONLY mode
- Primary Node Flexibility to divert SELECT queries on secondary node to best utilize the hardware resources operate in RW mode and Secondary node resides in READ ONLY mode
