Tenant-partitioning is required to scale a Cloud deployment to thousands and millions of tenants. This means that there are usually multiple clusters for a single Cloud service, and each of these service clusters handles a subset of the tenants in the system. Creating dynamic tenant clusters and tenant partitioning strategies are ongoing research areas. In such a tenant-partitioned deployment, the load balancers themselves need to be tenant-aware, in order to be able to route the requests to the proper tenant clusters. Therefore, the load balancer has to be both tenant-aware and service-aware, since the service clusters are partitioned according to the tenants. The WSO2 Load Balancer is tenant-aware as well as service-aware and is capable of routing messages in both these methods.
