Claim 4:
5. A computer-implemented method comprising:
obtaining age data reflecting ages of individual server computing devices within a fleet of server computing devices configured to implement workloads on behalf of client computing devices;
generating a relative probability distribution based on application of the age data to a probability density function, wherein the probability density function reflects relative probabilities to randomly select a server computing device from the fleet, wherein the relative probabilities are determined at least in part as a function of age of the individual server computing devices, and wherein the relative probabilities bias against selection of younger server computing devices relative to older server computing devices;
obtaining a request to route a workload to the fleet;
selecting a plurality of server computing devices at random from the fleet according to the relative probability distribution; and
routing the workload to a server computing device selected from the plurality of server computing devices.
