Methods, systems, and computer-readable storage media for selecting requests from a plurality of tenant queues in a multi-tenant system including actions of determining a plurality of weights, each weight being associated with a respective tenant in a set of tenants, each weight being dynamically adjusted based on a quota associated with the respective tenant for each iteration of a plurality of iterations within a period, selecting a tenant from the set of tenants based on the plurality of weights to provide a selected tenant, and transmitting a request from a request queue associated with the selected tenant for processing by a shared resource.

Tenant selection in quota enforcing request admission mechanisms for shared applications

Methods, systems, and computer-readable storage media for determining weights for selecting requests from a plurality of tenant queues in a multi-tenant system receiving measured response time and measured throughput for each tenant in a set of tenants being considered in a current period, for each tenant in the set of tenants, determining a weight based on respective measured response times and respective measured throughput, the weight being determined based on one of a previous weight, an initialized weight, a modified proportional and integral (PI) control, and a volunteer weight increase, providing a set of weights that includes weight for each tenant in the set of tenants, and transmitting the set of weights to an access mechanism, the access mechanism selecting tenant requests for processing by a shared resource.
