The Multicloud Resilience Myth: When a Second Cloud Reduces Risk and When It Multiplies It

This article debunks the common assumption that using multiple cloud providers guarantees resilience. It explains that simply having workloads in two clouds does not eliminate single points of failure if shared dependencies like DNS, identity, or deployment pipelines remain. Drawing on recent cloud incidents (AWS, Azure, Google Cloud), it argues that true resilience requires independent operational planes and rigorous testing, and suggests that multi-region within one provider is often a more practical first step. The piece emphasizes that resilience is proven by meeting RTO/RPO during failures, not by provider count.
