public final class BackendService
extends GenericJson
Represents a Backend Service resource. A backend service defines how Google Cloud load balancers
 distribute traffic. The backend service configuration contains a set of values, such as the
 protocol used to connect to backends, various distribution and session settings, health checks,
 and timeouts. These settings provide fine-grained control over how your load balancer behaves.
 Most of the settings have default values that allow for easy configuration if you need to get
 started quickly. Backend services in Google Compute Engine can be either regionally or globally
 scoped. * [Global](https://cloud.google.com/compute/docs/reference/rest/beta/backendServices) *
 [Regional](https://cloud.google.com/compute/docs/reference/rest/beta/regionBackendServices) For
 more information, see Backend Services.

 
 This is the Java data model class that specifies how to parse/serialize into the JSON that is
 transmitted over HTTP when working with the Compute Engine API. For a detailed explanation see:
 https://developers.google.com/api-client-library/java/google-http-java-client/json

getLocalityLbPolicy
public String getLocalityLbPolicy()
The load balancing algorithm used within the scope of the locality. The possible values are: -
 ROUND_ROBIN: This is a simple policy in which each healthy backend is selected in round robin
 order. This is the default. - LEAST_REQUEST: An O(1) algorithm which selects two random healthy
 hosts and picks the host which has fewer active requests. - RING_HASH: The ring/modulo hash
 load balancer implements consistent hashing to backends. The algorithm has the property that
 the addition/removal of a host from a set of N hosts only affects 1/N of the requests. -
 RANDOM: The load balancer selects a random healthy host. - ORIGINAL_DESTINATION: Backend host
 is selected based on the client connection metadata, i.e., connections are opened to the same
 address as the destination address of the incoming connection before the connection was
 redirected to the load balancer. - MAGLEV: used as a drop in replacement for the ring hash load
 balancer. Maglev is not as stable as ring hash but has faster table lookup build times and host
 selection times. For more information about Maglev, see

 field is not set to MAGLEV or RING_HASH, session affinity settings will not take effect. Only
 ROUND_ROBIN and RING_HASH are supported when the backend service is referenced by a URL map
 that is bound to target gRPC proxy that has validateForProxyless field set to true.

Returns:
value or null for none
