A county ERP team wants a cost-aware multi-Region DR design that keeps a minimal core warm in a second Region and scales out only when disaster strikes. Which pattern is that?
Select an answer to reveal the explanation.
Short Explanation
Pilot light is the night-light in the spare house—database and images ready, full lights and staff only when disaster hits.
Full Explanation
Pilot light DR maintains minimal critical components (often a cross-Region database replica and machine images) in a standby Region and scales application tiers during failover. It is cheaper than active-active while recovering faster than pure backup/restore. Mislabeling single-Region Multi-AZ as multi-Region DR is incorrect.
