Multi-Cloud Disaster Recovery: The Good, The Painful, and The “Why Didn’t We Think of That?”
A practical look at cross-cloud recovery architecture, replication, failover and the operational trade-offs that appear during real incidents.
This is a concise portfolio reading guide to my published Medium article. For the complete original text, examples and diagrams, use the Medium link below.
Why a second cloud?
A second provider changes the failure boundary, but introduces new operational complexity across networking, identity, deployment and observability.
A recovery architecture
The article describes AWS primary and GCP warm standby, Route 53 health-driven routing, PostgreSQL replication using Debezium and Kafka, and S3-to-GCS synchronization.
The difficult parts
Replication lag defines potential data loss; cold caches affect recovery performance; DNS behavior and failover testing must be planned rather than assumed.
