Multi-region serving and failover
Decide whether you need more than one region, choose between active-passive and active-active, size capacity so losing a region does not take you down (N-1 maths), steer traffic and fail over in seconds, handle state such as caches and conversations, respect data residency, and test the whole thing with game days.
A single region is simple. Everything runs in one place, one cloud console shows everything, and one network separates you from your users. It also means that a regional outage, a regional GPU shortage or a transatlantic latency complaint has no answer except "wait". Going multi-region answers those problems, and creates new ones: cost, consistency, operations. This lesson helps you decide whether and how.
