See [related docs](https://cloud.google.com/compute/docs/instance-groups/#specifying_service_endpoints) for details. Defaults to http. 79 80 * `project` - (Optional) The project in which the resource belongs. If it 81 is not provided, the provider project is used. 82 83 * `protocol` - (Optional) The protocol for incoming requests. Defaults to 84 `HTTP`. 85 86 * `region` - (Optional) The Region in which the created address should reside. 87 If it is not provided, the provider region is used. 88 89 * `timeout_sec` - (Optional) The number of secs to wait for a backend to respond 90 to a request before considering the request failed. Defaults to `30`. 91 92 93 **Backend** supports the following attributes: 94 95 * `group` - (Required) The name or URI of a Compute Engine instance group 96 (`google_compute_instance_group_manager.xyz.instance_group`) that can 97 receive traffic. 98 99 * `balancing_mode` - (Optional) Defines the strategy for balancing load. 100 Defaults to `UTILIZATION` 101 102 * `capacity_scaler` - (Optional) A float in the range [0, 1.0] that scales the 103 maximum parameters for the group (e.g., max rate). A value of 0.0 will cause 104 no requests to be sent to the group (i.e., it adds the group in a drained 105 state). The default is 1.0. 106 107 * `description` - (Optional) Textual description for the backend. 108 109 * `max_rate` - (Optional) Maximum requests per second (RPS) that the group can 110 handle. 111 112 * `max_rate_per_instance` - (Optional) The maximum per-instance requests per 113 second (RPS). 114 115 * `max_utilization` - (Optional) The target CPU utilization for the group as a 116 float in the range [0.0, 1.0]. This flag can only be provided when the 117 balancing mode is `UTILIZATION`. Defaults to `0.8`. 118 119 ## Attributes Reference 120 121 In addition to the arguments listed above, the following computed attributes are 122 exported: 123 124 * `fingerprint` - The fingerprint of the backend service. 125 126 * `self_link` - The URI of the created resource.
