Multi-Region Active-Active Architecture on AWS
Patterns and trade-offs for running active-active workloads across AWS regions: routing, data replication, conflict resolution, and what it actually costs you in complexity.

What is the real difference between active-active and active-passive multi-region?
Active-passive: only one region serves traffic. The other is a warm standby waiting for failover. Simpler, cheaper, but you pay for capacity that does nothing 99% of the time and the first failover is the first time you find out if the standby actually works. Active-active: both regions serve live traffic at the same time. Failover is mostly removing a region from rotation. The trade-off is you now have to solve writes in two places, conflict resolution, and consistent state across regions. The complexity jump is huge.
