Customized service request permission control system

Abstract:

Examples provide a permission service for controlling service requests to web services. A permission controller monitors the number of active requests to a selected web service. When a permission request associated with the selected web service is received from a client, the permission service compares the current number of active requests to a per-service maximum threshold number of active requests. The permission controller maintains a per-threshold number of active requests customized for each web service. If the current request would exceed the threshold number if granted, the permission controller sends a denial with a random wait time to the client. The client resends the permission request on expiration of the wait time. The permission controller generates a different random wait time for each denial response. If the number of active requests is less than or equal to the threshold, the permission service grants permission to the client.
