Neutron-to-Neutron: interconnecting multiple OpenStack deployments
Provide network interconnections between Openstack clouds/regions ?
Neutron offers floating IPs and IPSec VPNaaS. However this is not always good enough: sometimes network isolation is needed, but without the the overhead of IPSec encryption.
How to avoid putting the burden on an orchestrator ?
Solutions exist to create interconnections in ways specific to each overlay technology or SDN backends, but they require central coordination via an orchestrator (not always easy), and sometimes also the provisioing of network devices (not always simple).
"Neutron talking to Neutron"
This talk exposes a solution developed in the Neutron project, where tenants define their network interconnection needs across regions or clouds, and Neutron components in the different regions coordinate together to setup these private isolated interconnections. Without orchestration nor network device configuration.
This talk will give a status of the implementation work based on Neutron specifications.
