Overview

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.

#locality_lb_policy ⇒ String

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 https://ai. google/research/pubs/pub44824 This field is applicable to either:
  • A regional backend service with the service_protocol set to HTTP, HTTPS, or HTTP2, and load_balancing_scheme set to INTERNAL_MANAGED.
  • A global backend service with the load_balancing_scheme set to INTERNAL_SELF_MANAGED. If sessionAffinity is not NONE, and this field is not set to MAGLEV or RING_HASH, session affinity settings will not take effect. Only the default ROUND_ROBIN policy is 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.
