Hi Saverio, First, please note, in the future the best tag for load balancing is [octavia] as it is no longer part of the neutron project.
I am sorry that you are so anxious and confused about the current state of load balancing for OpenStack. Let me clarify a few things: 1. LBaaSv2 is not going away and is not deprecated. The neutron-lbaas code base is going into deprecation in favor of the octavia code base. I will highlight two things, among others, we are doing to ease this transition for operators: a. For some time into the future you will be able to continue to use LBaaSv2 via neutron using the proxy driver in neutron-lbaas. b. There will be migration procedures and scripts that will move, in place, load balancers from neutron-lbaas into octavia. 2. Deprecation means we will not continue to develop features for neutron-lbaas, but it will remain in the code base for at least two more releases and continue to receive bug fixes. It's a formal way of saying, hey, in the future we are going to remove this. 3. New features will be added to the octavia code base. It is only neutron-lbaas that will be going into feature freeze for new feature development due to the transition. 4. Any tools written against the neutron endpoint for neutron-lbaas using the LBaaSv2 API will work with Octavia by updating the endpoint you are pointing to from neutron to octavia. 5. We are not making any changes to stable/liberty, stable/mitaka, stable/newton, or stable/ocata releases. I will note, per OpenStack stable release policy, liberty is EOL and mitaka will be next month and we are not allowed to add new features to any previous releases. Please see the OpenStack stable policy here: https://docs.openstack.org/project-team-guide/stable-branches.html 6. Octavia was available and, in fact, the reference load balancing driver in Liberty. 7. Multiple operators are represented on the core review team for octavia. We try really hard to listen to feedback we get and to do what is best for folks using load balancing in OpenStack. It is unfortunate our presentations at the Barcelona summit were denied and we did not get an opportunity to share our plan with the community and get feedback. If you have concerns I encourage you to reach out to us via our weekly IRC meetings, our channel on IRC #openstack-lbaas, or via the mailing list with the [octavia] tag. As you know, I have been responding to your emails with load balancing questions. To answer Zhi's e-mail: This is correct, if you are using the legacy haproxy namespace driver, and not the octavia driver, there is currently no easy method to migrate the ownership of a load balancer from one agent to another. The legacy haproxy namespace driver is/was not intended for high availability. If you want a highly available open source load balancing option, I highly recommend you use the octavia driver instead of the haproxy namespace driver. It was designed to provide scale and availability. You would not have the issue you are describing with the octavia driver. That said, if you want to continue to develop new features for the haproxy namespace driver, we should start planning to do so in the octavia code base. We will be starting work on a port of the haproxy namespace driver into octavia soon. We are however discussing what the future should be for this driver given its limitations. I think the best plan will be to port it over into a standalone driver that folks can contribute to if they have a need for it and we can deprecate it if there is no longer support for it.

So if we look at deployments with more than 100 servers NO ONE IS USING NEWTON yet. And I scream this loud. Everyone is still in Liberty or Mitaka. I am just struggling to upgrade to LBaaSv2 to hear that is already going into deprecation. The feature Zhi is proposing is important also for me once I go to production. I would encourage devs to listen more to operators feedback. Also you devs cant just ignore that users are running still Liberty/Mitaka so you need to change something in this way of working or all the users will run away. thank you Saverio On 16/03/17 16:26, Kosnik, Lubosz wrote: > Hello Zhi, > Just one small information.
