Juno lbaas (v1) has pool as the root model, with VIP.

Kilo lbaas (v2), you are correct, vip is splitting into loadbalancer and listener, and loadbalancer is the root object. And yes, the new objects get new URIs.

Both v1 and v2 plugins will be available in Kilo.

Subject: [openstack-dev] Querries Regarding Blueprint for LBaaS API and Object Model improvement

Hi All,

I wanted to know the approach has been followed for LBaaS implementation in Openstack (juno) out of the following in the link<https://etherpad.openstack.org/p/neutron-lbaas-api-proposals>(https://etherpad.openstack.org/p/neutron-lbaas-api-proposals). Is it-

  1.  Existing Core Resource Model
  2.  LoadBalancer Instance Model
  3.  Vip-Centric Model

Currently I find Pool as the root object that has a VIP associated with it rather than Listeners and LoadBalancers in various openstack documents.

But while investigating the same, I came across a blueprint<https://blueprints.launchpad.net/neutron/+spec/lbaas-api-and-objmodel-improvement> (https://blueprints.launchpad.net/neutron/+spec/lbaas-api-and-objmodel-improvement) for LBaaS Api and object model improvement. It talks about moving the current VIP object to Listener and Listener will be linked to a LoadBalancer in the upcoming releases,

I wanted to know the current approach followed for openstack-juno and if in the upcoming releases(Kilo)-

  *    Are we planning to have new APIs for /Listener and /Loader and there will be no VIP object and its corresponding API.
  *    Or we will be having VIP object and its corresponding API, creation of which will result in creation of Loadbalancer and /Listener at the backend itself.

If you find the above investigation incorrect, please feel free to point to the right direction.

Thanks & Regards
Shreshtha Joshi
