All load balancers utilize an algorithm that defines how traffic should be directed between
back-end nodes. The default algorithm for newly created load balancers is RANDOM, which can
be overridden at creation time or changed after the load balancer has been initially
provisioned. The algorithm name is to be constant within a major revision of the load
balancing API, though new algorithms may be created with a unique algorithm name within
a given major revision of the service API.
