On This Lesson 4 topics
This lesson is planned. The outline below lists the topics it will cover. The full lesson has not been published yet.
In this lesson
decide whether multi-region is justified by a requirement.
Planned topics
- Valid reasons: survive a regional outage, lower latency for distant users, data residency law.
- Invalid reasons: it sounds resilient, a competitor does it.
- Costs: duplicate infrastructure, data replication, operational complexity, harder testing.
- Define RPO (data loss tolerated) and RTO (downtime tolerated) before choosing.
Draft outline details
Demonstration
a requirements card: regions lost, RPO, RTO, latency target, residency rules, budget; used to filter designs.
Check your understanding

Show answer
Regional outage tolerance and data residency (or latency).
