Description

To provide support for multi-tenant applications, the load balancer needs to identify the host name (or mapped domain name if available) and the tenant id from the incoming request and delegate that request to the next available member in the relevant cluster.

Tenant Definition:

• A tenant could be partitioned into clusters by defining tenant ranges for each cluster.
  Example: (Cluster 1 - Tenant Range: 1-100, Cluster 2 - Tenant Range: 101-200, Cluster 3: Tenant Range: 201-*)
• Each tenant needs to define an id and a domain name.

Properties found in the Request URL:

• Host name
• Tenant id or tenant domain name

Required Functionality:
1. If tenant id is found in the request URL identify the cluster and delegate the request to the next available member.
2. If tenant domain is found in the request, find the tenant id using the available tenant information and execute 1.

Tenant Information:
Stratos Manager (SM) needs to publish tenant information to a message broker topic so that coupling between the load balancer and SM is less. As a result the load balancer could operate in isolation just by communicating with the message broker.
