Emergency dispatch case stores must recover within minutes, while a best-effort monthly park-usage dashboard can tolerate longer outages. How should resilience be designed?
Select an answer to reveal the explanation.
Short Explanation
Not every toaster needs a nuclear bunker. Match DR tiers to how badly the city hurts when that store is down—dispatch is not the same as a nice-to-have park chart.
Full Explanation
Resilience architecture aligns recovery objectives with business criticality and data criticality. Critical operational stores typically require tighter RTO/RPO and tested failover, while best-effort analytics can accept softer tiers. Uniform over-engineering wastes budget; under-protecting life-safety or core service systems creates unacceptable risk. Explicit tiers make those trade-offs visible and fundable.
