A method for selecting a service endpoint from a plurality of service endpoints in a distributed system of a service provider may include storing processing data for each of the plurality of endpoints. A success rate may be calculated for each of the plurality of service endpoints and based on a number of processed requests from a plurality of received requests. An average latency may be calculated based on latency associated with each of the processed requests. A latency score may be calculated based on a minimum average latency and the average latency. A raw score may be calculated based on the latency score and the success rate. A selection weight may be calculated based on the raw score and a balancing parameter. One of the plurality of endpoints may be selected based on the selection weight.
