Agreed it is hard for those reason you specified. To do it, first I would not use any cloud features that cannot be easily setup in another cloud. So no lambd

Agreed it is hard for those reason you specified. To do it, first I would not use any cloud features that cannot be easily setup in another cloud. So no lambdas. Just k8s clusters, maybe DBs if they can be setup to backup between clouds. I was able to migrate from AWS k8s to DO K8S very easily.... just pointed my k8s configs to the new cluster (plus configuring the DO load balancers). In my case, I need the dynamic DNS (havnt looked into it yet), auto-scaling is already setup with k8s, and the DB backups between DBs (next project).
