The invention refers to a system for real-time resource consumption control in a distributed environment and a corresponding method, the system comprising: a multitude of server instances (Sx) having access to shared resources, whereby each request for a shared resource issued by a client application (CA) is handled by one of the server instances (Sx); a global resource consumption counter (G), representing the overall resource consumption of the multitude of server instances (Sx) at a given time; and a multitude of proxy servers (Lx), each proxy server comprising — a receiver module (R) for receiving resource consumption requests issued from a client application (CA), — a resource consumption decision module (Dm) for accepting or rejecting a resource consumption request, — a queue (Q) for collecting resource consumption requests that have been locally accepted by the respective proxy server (Lx), — a local resource consumption counter (L), representing the global resource consumption as seen by the respective proxy server (Lx), said local resource consumption counter (L) being updated every time a resource consumption request is accepted by the decision module (Dm), the updated value being provided in turn as an input to the decision module (Dm), and — a synchronization module (S) for synchronizing the global resource consumption counter (G) by interfacing with all other server instances (Sx). |
