/**
 * A Region Backend Service defines a regionally-scoped group of virtual
 * machines that will serve traffic for load balancing.
 *
 * > **Note:** Recreating a `gcp.compute.RegionBackendService` that references other dependent resources like `gcp.compute.InstanceGroup` will give a `resourceInUseByAnotherResource` error, when decreasing the number of other dependent resources.
 * Use `lifecycle.create_before_destroy` on the dependent resources to avoid this type of error as shown in the Dynamic Backend Count example.
 *
 * To get more information about RegionBackendService, see:
 *
 * * [API documentation](https://cloud.google.com/compute/docs/reference/latest/regionBackendServices)

     * hosts and picks the host which has fewer active requests.

     * hashing to backends. The algorithm has the property that the

     * 1/N of the requests.

     * to the same address as the destination address of

     * was redirected to the load balancer.

     * UNAVAILABLE_WEIGHT. Otherwise, Load Balancing remains

     * from Backend reported Custom Metrics. If set, the Backend Service
     * responses are expected to contain non-standard HTTP response header field
     * X-Endpoint-Load-Metrics. The reported metrics
