Load balancing requests such that target resources serve a single client

Abstract:

Various embodiments of methods and apparatus for load balancing requests such that target resources serve a single client are described. In at least some embodiments, a single resource, such as a compute instance, is assigned to only one client, and that single resource is used for all subsequent connections and communications from that client. Some embodiments comprise a resource selection system which provides identifying information of an available resource, in order for a connection to be established between the client and the resource. The resource selection system then removes that identifying information from its memory. In some of these embodiments, a routing layer interfaces with the resource selection system to establish the connection between the client and the available resource. When a client is assigned to a resource, other clients may be prevented from establishing connections with the resource.
