Claim 13:
14. One or more non-transitory computer-readable media comprising computer executable instructions that, when executed by a computing system including a fleet of servers, cause the computing system to:
obtain age data reflecting ages of individual servers within the fleet;
generate 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 from the fleet, wherein the relative probabilities are determined at least in part as a function of age of the individual servers, and wherein the relative probabilities bias against selection of younger servers relative to older servers;
obtain a request to route a workload;
select a plurality of servers at random from the fleet according to the relative probability distribution; and
route the workload to a server selected from the plurality of servers.
