/**
* 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.
*
* Accepted options are:
*
* * LEAST_CONNECTIONS: The node with the lowest number of connections will
* receive requests.
*
* * RANDOM: Back-end servers are selected at random.
*
* * ROUND_ROBIN: Connections are routed to each of the back-end servers in turn.
*
* * WEIGHTED_LEAST_CONNECTIONS: Each request will be assigned to a node based
* on the number of concurrent connections to the node and its weight.
*
* * WEIGHTED_ROUND_ROBIN: A round robin algorithm, but with different
* proportions of traffic being directed to the back-end nodes. Weights
* must be defined as part of the load balancer's node configuration.
