Multi-cloud: when the operational tax is worth it
Use "Multi-cloud: when the operational tax is worth it" to tell the cases apart, then choose a response for each one.
Step 1 of 2
Multi-cloud: when the operational tax is worth ita second provider is a big commitment
Multi-region on one cloud handles most resilience needs. A second cloud provider doubles your IAM models, networking primitives and on-call surface and you lose the deep integrations that make one cloud productive. Reach for it only with a concrete driver.
A specific resource is only available or affordable elsewhere - e.g. GPU capacity for inference at a price or scale your primary cloud can't meet.
A customer or regulatory requirement mandates provider diversity.
Provider-level outage risk is genuinely existential to the business.
You just want "resilience" - multi-region on one cloud already gives you that for far less.
You'd run a lowest-common-denominator stack and forfeit managed services to stay portable.
The team is small and flat - every added platform is permanent on-call and toil.
When asked "would you go multi-cloud?", resist the heroic yes. The senior answer is: "Multi-region on AWS first - it covers latency and resilience. I'd add a second provider only for a concrete driver like GPU supply for inference and I'd scope it to that workload rather than mirroring the whole platform." Decisive, cost-aware and scoped beats ambitious and vague.
