Finance questions why warm standby for the utility outage portal costs more than backup-only restore. How should the architect frame the trade-off?
Select an answer to reveal the explanation.
Short Explanation
Warm standby is the hotel room you keep reserved—pricier than a suitcase in storage, ready when the storm hits. Pay for it when citizen SLAs say restore-from-scratch is too slow. Cheap DR that misses RTO is expensive in headlines.
Full Explanation
Warmer DR patterns such as warm standby maintain more running capacity and therefore cost more than backup-and-restore. Architects should quantify that cost against RTO, RPO, and citizen-facing SLAs. If restore-from-scratch cannot meet required recovery times, the incremental spend may be justified. Claiming warm standby is always cheaper, that backups always meet aggressive RTO, or that cost is unrelated to objectives misstates the trade-off.
