We seem to have multiple classes within 'core' that act as advisors for determining the application's deployment-type.
Maybe we need to rethink and cleanup. I think it should be sufficient to have one and only one place to configure the deployment type. eg. simply via a single environment variable.
To pick up this idea , we could introduce one layer of abstraction. Also note: We need to have access to this variable very early in the bootstrapping phase.
