Ok.. so that still doesn't answer my question. How do you get the time and resources allocated to make your entire platform completely agnostic of specific cloud services while still operating in the cloud? Can you name a single company where that's done and they talked about it at all? We're talking about at least tripling developer workloads and general operating costs here and finding developers who can navigate different cloud and on-premise providers for... what?

Even small companies have multiple engineering teams, and each of those teams has particular needs, and each of the engineers, analysts or general users may rely on some service AWS, GCP or some other cloud provider has. Any single person can now break this ideal flexibility requirement if it makes their life easier.
