Abstract

A technology for routing traffic from similar users to a same server cluster to improve data center efficiency is disclosed. When a traffic routing server receives a request from a user, the traffic routing server determines an identifier of a partition to which the user is assigned. The user and many other users with whom the user shares a social attribute are co-located in the same partition. The traffic routing server then computes a hash of the identifier using a hash function and locates a server cluster on a consistent hash ring using the computed hash. The traffic routing server then sends the request from the user to that server cluster. By consistently sending requests from users assigned to the same partition to the same server cluster, the technology improves cache hit rates and reduces data duplication across the server clusters, which in turn improves datacenter efficiency.
