One-to-many stateless load balancing

摘要

A stateless load balancer may route a request to a computing device without tracking state information of the communication connection that delivered the request. The stateless load balancer may receive a request that is initiated by a client device. The request may be transported to the stateless load balancer via a communication connection that includes a public destination internet protocol (IP) address. One of the routing devices in the stateless load balancer may obtain connection tuples of the communication connection that transported the request, in which the connection tuples include the public destination IP address. Once obtained, the routing device may generate a hash value from one or more connection tuples. Subsequently, the routing device may map the hash value to a target network address of a particular computing device in a cluster of multiple computing devices by accessing stored mapping data, and then route the request to the particular computing device for processing.

1. A stateless load balancer comprising:
one or more processors; and memory storing components executable by the one or more processors, the components perform acts comprising:
receiving a request that is initiated by a client device, the request being transported to the stateless load balancer via a communication connection;obtaining connection tuples of the communication connection;generating a hash value from the connection tuples;mapping the hash value to a first network address of a first computing device, based at least in part on mapping data;updating the mapping such that the hash value is mapped to a second network address of a second computing device; androuting the request to the second computing device.
