1) Is there a name for the service model that's between open-source, and a software service? I'm specifically thinking of the model where you let users run your service as a binary inside their platform/cloud/VPC, but you also offer a hosted version. Sort of like [0]Metabase or [1]Terraform?

2) Are there many successful examples of this?
