Active-Passive
For Application Services + SQL
Active–passive redundancy ensures high availability by pairing a primary node with at least one standby node that takes over in the event of the primary node's failure. Consistency and failover are handled within the solution in a manner that is transparent to external consumers. While this approach provides basic protection against hardware outages, it inherits cybersecurity weaknesses stemming from deep node trust and byte-for-byte SQL replication.
