For EC2, this is hidden behind symbolic names for the regions, e.g.
eu-west-1 and us-east-1.

Some of that is done by some rack middleware magic. The EC2 driver gets
the provider (~ region) with this code:
endpoint = (Thread.current[:provider] || ENV['API_PROVIDER'] ||
DEFAULT_REGION)
though we should probably hide that behind some helper for drivers;
