For that matter, "good" (in my opinion) OpenStack service providers hand out relevant network configuration via DHCP/SLAAC which shouldn't need any special handling at all. ConfigDrive has the potential downside of being static for the lifetime of the server instance, while the EC2 metadata service is a horrible SPoF which you often see overloaded and timing out requests causing instances to fail to boot entirely. -- Jeremy Stanley
