Overview

Represents a Backend Service resource. Backend services must have an associated health check. Backend services also store information about session affinity. For more information, read Backend Services. A backendServices resource represents a global backend service. Global backend services are used for HTTP(S), SSL Proxy, TCP Proxy load balancing and Traffic Director. A regionBackendServices resource represents a regional backend service. Regional backend services are used for internal TCP/UDP load balancing. For more information, read Internal TCP/UDP Load balancing.

#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, refer to 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.
