Its really just a binary that activates https://github.com/openstack/nova/blob/master/nova/api/metadata/handler.py#L100

Its a way to allow for a VM to get metadata about itself and any userdata (of which users may have provided) on boot.

Said feature is not just connected to ec2, but provides a generic mechanism for getting this type of data to an instance.

The ec2 folks I believe are just the 'originators' of said concept and that’s how it got named initially.

Subject: [Openstack] Nova metadata service

Hi guys!

After looking for in the mailing list and docs, I honestly still don't understand what really is nova-api-metadata.
it's a mandatory service in a multi-host deployment? it's only related to EC2?

Thanks!

Regards,
JuanFra.
