[openstack-dev] [Quantum][LBaaS] - LBaaS Extension in Quantum Plugin

Hi Balaji,
*
*
With current lbaas implementation the link that you've provided is not
actual as current implementation has adopted different architecture.

*> Can you please through some light on the Agent part of the architecture
like where exactly the agent will be running like OpenStack Controller Node
or OpenStack Compute Node.?*
In grizzly, lbaas agent should run on some node - it could be compute node
or network controller node.
The only important is that there MUST be only one instance of lbaas agent
running.

Current implementation only supports haproxy-on-the-host solution so it's
not suitable for hardware/VM LBs.
Support for such use case is planned in the next release.

Thanks,
Eugene.
