A grants portal DR design should keep a minimal core data plane running in a standby Region and scale out only after disaster declaration. Which pattern is that?
Select an answer to reveal the explanation.
Short Explanation
Pilot light is the furnace pilot—tiny flame always on, burners roar when you need heat. Grants portal keeps a skinny core warm, then scales out when disaster is declared. Full active-active or zero standby are different budgets and RTOs.
Full Explanation
The pilot light pattern keeps essential data stores or core services replicated and minimally running in a recovery Region while leaving most application capacity to be launched or scaled at failover time. That differs from warm standby (more capacity always up), multi-site active-active (both sites serve users), and pure backup/restore (little or no pre-provisioned stack). It matches a grants portal that intentionally defers full scale-out until disaster declaration.
