  • Publication number: 20210044497
    Abstract: A system and computer-implemented method for enforcing parameters of resource consumptions. A controller receives, via a node in a distributed computer network, a request from a requester for one of services to be provisioned by a plurality of servers. The plurality servers are accessible via the distributed computer network. The controller identifies parameters of resource consumption from a data store of the plurality of servers in the distributed computer network system as a function of outstanding requests from requesters. The controller determines if the parameters of resource consumption is less than a resource threshold. If the determination is positive, controller compares the request to a total number of requests before accepting the request. If the determination is negative, the controller compares the request to the parameters divided by a number of nodes before accepting. The controller schedules the accepted request for execution.
