Hi Sumit, I also got confused with service VM and service instance definition. I assumed both being the same and hence the networks question.

I believe the logic for scaling, and or clustering multiple service VMs to map to a logical service instance would lie in the service plugin which realizes the logical service instance. Can you please elaborate on the service/use-case where you would need to plug the VM into different networks? Thanks, ~Sumit.

It would also have impact on the VIF scheme. How can we plug these services into different networks - is that still being worked on?

Based on input and feedback, here is what I see so far. Assumptions: - a 'Service VM' hosts one or more 'Service Instances' - each Service Instance has one or more Data Ports that plug into Neutron networks - each Service Instance has a Service Management i/f for Service management (e.g. FW rules) - each Service Instance has a VM Management i/f for VM management (e.g. health monitor) Use case 1: Private Service VM Owned by tenant VM hosts one or more service instances Ports of each service instance only plug into network(s) owned by tenant Use case 2: Shared Service VM Owned by admin/operator VM hosts multiple service instances The ports of each service instance plug into one tenants network(s) Service instance provides isolation from other service instances within VM Use case 3: Multi-Service VM Either Private or Shared Service VM Support multiple service types (e.g. FW, LB, …) - Greg _______________________________________________ OpenStack-dev mailing list OpenStack-dev@lists.openstack.org<mailto:OpenStack-dev@lists.openstack.org> http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev _______________________________________________ OpenStack-dev mailing list OpenStack-dev@lists.openstack.org<mailto:OpenStack-dev@lists.openstack.org> http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev _______________________________________________ OpenStack-dev mailing list OpenStack-dev@lists.openstack.org<mailto:OpenStack-dev@lists.openstack.org> http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
