1. A resource-aware system for managing request traffic based on a management policy, comprising: a node comprising; an analyzer system individually monitoring a performance, responsive to the request traffic, of each of a plurality of system resources in a set of system resources, every system resource in the set of system resources being of a different hardware type and handle handling a portion of the request traffic, and determine when at least one of the set of system resources is approaching an overload condition based on the management policy and a monitored performance of the at least one of the set of system resources; and a planning system identifying and implementing a corrective action to avoid the overload condition, the corrective action including restricting selected requests, having a first load characteristic, handled by the at least one of the system resources approaching the overload condition without restricting other requests, having a second load characteristic lower than the first load characteristic, handled by the at least one system resource, the restricting based upon the respective load characteristics, wherein the corrective action is identified based on the at least one system resource that is approaching the overload condition and the management policy, and wherein the corrective action comprises adjusting a queue priority of a type of request in the request traffic based on the at least one system resource that is approaching the overload condition.
