IMO, multi-cloud doesnt make sense in 99.9% of the cases, as it defeats the idea of cost optimized solutions, brings in immense complexity, complex operations, additional overhead of multi-cloud management.
Its only practical for an application that can suffer no downtime, irrespective of the scale of failure and money as no-objective, because application failover across cloud, app stack setup for different cloud components will take large effort and cost.
Most common selling point for Multi-cloud strategy is DR, but, with each cloud increasing zones in each region, a region failure has never happend, hence, it make it less and less of a point as time goes on. Making application multi-region will itself suffice. Anything above that is simply over-kill for 99.9%.
.1% of those applications may be Global Infra backbone!
