A first reverse proxy appliance of the plurality of reverse proxy appliances receives an incoming transaction. A machine logic determines that the incoming transaction cannot be directly processed by the first reverse proxy appliance based, at least in part, upon the current threshold level of the first reverse proxy appliance and the current transaction count of the first reverse proxy appliance. Responsive to the determination that the incoming transaction cannot be directly processed by the first reverse proxy appliance, a second reverse proxy appliance of the plurality of reverse proxy appliances and a third reverse proxy appliance of the plurality of reverse proxy appliances negotiate in order to determine that the third reverse proxy appliance will process the incoming transaction. Responsive to the negotiating, the incoming transaction is sent to the third reverse proxy appliance.

Processing incoming transactions based on resource utilization status of backend systems in an appliance cluster

A method, system, and/or computer program product synchronizes Service Level Monitoring (SLM) statuses of a plurality of appliances in a cluster. A token, which comprises a global SLM data and loading distribution information, is received at a first appliance. The global SLM data and loading distribution information of the token is retrieved from the token. The token is updated with local statistics for the first appliance. The updated token is then passed to a next appliance.
