Cool concept. In my experience, the biggest headache/expense is data migration, and not software migration. As long as the stack is vendor neutral, it's not the long-poll, though it is gruntwork.

In the SaaS world, maybe this will be useful to run managed cloud services? (That is, customer A wants a private instance in AWS and customer B wants it in Azure)

Yes data migration is definitely the most gnarly part. We regularly migrate databases with zero downtime using Bucardo (we detail it here: https://www.porter.run/blog/migrating-postgres-from-heroku-t...) and will be addressing this part of the migration in the ejection process in the future as well.

Crunchy Bridge seems to make the data migration simple too - https://docs.crunchybridge.com/migrate/heroku_dump_restore
