Abstract:
Message oriented middleware (MOM) provides a messaging service layer between the transport and application layer of the networking protocol stack. A resilient MOM system strives to provide a required level of message brokerage service in the face of bursty surges in workload demand, and failures in the underlay network or brokers. Resilience in our MOM system is achieved by a novel workload allocation mechanism which minimizes the quantified risk of workload exceeding capacity of a broker, while introducing redundant mirroring of workload; and also using resilient overlay routing and multi-homing to mitigate and recover from underlay network failure(s). This paper discusses the overall system architecture and the workload allocation and mirroring mechanism we employed. Comparing with round robin maximizing resource reserve ratio, our allocation algorithm provides superior resilience in minimizing the risk of correlated workload exceeding the capacity of system.
