"Multi-cloud" only works if you stick with the basics. Like disk storage, compute, and a well-supported database. Once you tie in into a cloud's specific offerings.....

I find the Anthos docs and talks so confusing. Half of them say Anthos is for hybrid between on-prem and GCP. The other half say it's for multicloud and hybrid.
There was actually a project called “spinnaker” that was supposed to solve this problem.
Whether the cost of paying 2 or more cloud providers is worth it for most companies is up in the air.
