Multi-cloud DR diagrams are easy. Tested failover with clear RTO/RPO is hard. Start with business objectives and data gravity before drawing arrows across providers.
Many teams need multi-region on one cloud more than dual-cloud active-active. Be honest about consistency, cost, and operational skill required.
Automate backups, test restores, and rehearse runbooks. Untested DR is fiction.
Design for the failure you can detect and recover from—not the logo count on a slide.
Identify data stores that cannot be dual-written cheaply; design around them explicitly.
Include DNS, identity, and secrets in failover drills—apps alone are not enough.
Budget for idle capacity or warm standbys; DR that exists only on slides fails on game day.
Key takeaways
- Write honest RTO/RPO before drawing multi-cloud arrows.
- Multi-region on one cloud often beats dual-cloud active-active for most teams.
- Untested failover is fiction—drill restores and runbooks.
FAQ
When is multi-cloud DR justified?
When business requirements and data gravity truly demand provider diversity and you can staff the operational complexity.
What should every DR program include?
Backup automation, restore tests, clear ownership, communication plans, and measured recovery times—not only architecture diagrams.
