WEaaS                                                                    

Watch Endpoints as a Service project for Red Hat. WEaaS is for use with Kuryr and OpenStack.

WEaaS (a.k.a stop polling all the things) is offered as a more efficient alternative to monitor endpoints by tapping directly into Neutron's messaging queue. Currently, the Kuryr Controller polls the Neutron using the OpenStack API to watch for networking events. By communicating directly with RabbitMQ, OpenStack's messaging service, WEaaS is able to return endpoint information faster than polling.

Intended client: Kuryr Controller
