Cold Standby vs. Warm Standby
While planning for disaster recovery, the choice between Cold Standby and Warm Standby solutions can significantly impact business continuity. While both approaches aim to minimize downtime, they differ in their readiness levels and resource utilization. In Cold Standby there is minimal resource allocation until activation, offering cost efficiency but slower recovery times. In contrast, Warm Standby maintains partially active resources, enabling quicker response but with higher operational costs.
