Overview

LBaaS (Load-balancer-as-a-Service) is Quantum extension that introduces load balancing feature set into the core. It became a sub-project of Quantum per decisions in "San Diego Oct-2012 Design Summit" since there was huge interest from Vendors and Community to participate in this effort.

Current Design Discussions + whats need to be done

1. Initial Discussions Document NetworkLoadBalancingIntegrationsWithQuantum
   • May need to specify workflow of LB provisioning in all scenarios that LBaaS is going to support.
2. Object Model proposal - LBaaS/CoreResourceModel/proposal
   • All agreed upon. Might need minor update to include resources needed for device management (HW device catalog)
3. Tenant REST API - main proposal Quantum/LBaaS/API_1.0
   • Discussion about tenant_id in URL ended with most people agreeing to go with 2.0 style or URL (no tenant_id in URL)
4. Service Insertion - Spring Proposal ServicesInsertion and Fall Proposal Quantum/ServiceInsertion
   • Things to be discussed:
     1. Insertion modes: what is simplest and what should be implemented in the first place.
     2. changes in existing resource model (router)
     3. service catalog configuration
     4. API
5. Agreed on:
   1. Single Plugin per service type at a time. Vendor specific device access is implemented via drivers. Drivers could provide vendor-specific extra features. 1:1 mapping between extensions and plugins.
6. Provider API / Device Management - proposal Quantum/DeviceManagementAPI
   • The document describes API/process of registering a physical appliance as an LB device.
7. Balancer provisioning - proposal Quantum/LBaaS/Provisioning/proposal
   • The document needs to be updated with workflows that correspond to (1)
8. Overall code architecture proposal Quantum/LBaaS/Architecture
   • Contains overall picture of components and what they do. Sequence diagram needs to be updated according to latest decision about async execution.
9. Miscellaneous
   1. Device Locking - proposal Quantum/LBaaS/Architecture/ConcurrentRequests
   2. Asynchronous execution (discussion):
      • Client gets immediate response with Job ID which it polls later on. May need to have short design spec on this.
10. Inter-service resource dependency (discussion):
    • Resources of different advanced services may depend on one another. Solution options: (?)
