What is multi-region resilience?
In short
Multi-region resilience is the architectural pattern of running a service across more than one cloud region so that loss of a region does not cause loss of service.
Short answer
Multi-region resilience is the architectural pattern of running a service across more than one cloud region so that loss of a region does not cause loss of service.
What this actually means in practice
It's expensive — replication, traffic routing, data consistency and operational complexity all multiply. Most workloads should be multi-AZ first and multi-region only where regulatory or business impact demands it.
The most common pitfall
Going multi-region for marketing reasons and discovering the operational tax in incident #1.
What to do next
Decide multi-region from impact tolerances, not from architecture taste.
