Re: [openstack-dev] [Openstack] Need unique ID for every Network Service
Hi Roger, Yes, I agree with your comments. Following are the few use cases for LBaaS-UUID: i) There is a need for common configuration support for SLB's in Network Node and the SLB's deployed [using Network Service Chains] for East-West traffic for a Tenant. To map the configuration for Network Node - SLB and Service Chain - SLB, we need UUID for each SLB configuration. So that we can map the configuration based on Tenant network requirements. ii) To support multiple Configurations to SLB, UUID of SLB can be useful to map the configuration dynamically.

This is regardless of how many of them are per tenant or host or whatever. This discussion may be semantics, but just to be clear, LBaaS is the service that is called to create an LB. On the surface, it makes sense that you would only have one Service running per tenant; every object or instantiation created by that service (a Load Balancer, in this case) must have a UUID. I can't imagine why you would want multiple LBaaS services running at the same time, but again my imagination is limited. I am sure someone else has more imagination, such as a tenant having two vApps located on hosts in two different data centers, and they want an LBaaS in each data center since their inventory system or whatever is restricted to a single data center. If there were like two or three LBaaS' running, how would Neutron or Heat etc. know which one to call (criteria) when the network changes? It would be like having two butlers. A UUID on each Load Balancer is needed for alarming, callbacks, service assurance, service delivery, service availability monitoring and reporting, billing, compliance audits, and simply being able to modify the service. If there is an n-ary tuple relationship between LB and anything, you might be inclined to restrict only one LB per vApp. However, for ultra-high volume and high-availability apps we may want cross-redundant LB's with a third LB in front of the first two; that way if one gets overloaded or crashes, we can route to the other. A user might want to even mix and match hard and soft LB's in a hybrid environment. So, even in that use case, restricting the number of LB's or their tupleness is restrictive. I also want to say to those who are struggling with reasonable n-ary relationship modeling: This is just a problem with global app development, where there are so many use cases out there. It's tough to never say never, as in, you would never want more than one LBaaS per tenant.
