What are the Types of Redundancy in Email Marketing Servers?
There are several types of redundancy employed in email marketing servers:
Cold Standby: Backup servers are in a powered-off state until needed. This approach saves resources but may result in a brief delay during a failover. Warm Standby: Backup servers are running with minimal operations, allowing for faster failover compared to cold standby. Hot Standby: Backup servers are fully operational and can take over immediately in case of a failure, ensuring minimal disruption.
