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.

1. Object Model proposal - LBaaS/CoreResourceModel/proposal

 All agreed upon. 
 Might need minor update to include resources needed for device management (HW device catalog)

1. 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)

1. Service Insertion - main proposal Quantum/ServiceInsertion

 Things to be discussed:

1. Code architecture: multiplugin / multivendor approach, changes in infrastructure (extension and plugin frameworks)
2. changes in existing resource model (router)
3. service catalog configuration
4. API
5. Provider API / Device Management - proposal Quantum/LBaaS/RESTAPI/ProviderAPI

 The document describes API/process of registering a physical appliance as an LB device.

1. Balancer provisioning - proposal Quantum/LBaaS/Provisioning/proposal

 The document needs to be updated with workflows that correspond to (1)

1. 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.

1. 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.

1. Inter-service resource dependency (discussion):

    Resources of different advanced services may depend on one another. Solution options: (?)
