# google_compute_region_backend_service
8+
9+
Get information about a Regional Backend Service. For more information see
10+
[the official documentation](https://cloud.google.com/compute/docs/load-balancing/internal/backend-service) and
11+
[API](https://cloud.google.com/compute/docs/reference/rest/beta/regionBackendServices).
12+
13+
## Example Usage
14+
15+
```hcl
16+
data "google_compute_region_backend_service" "my_backend" {
17+
name = "my-backend-service"
18+
region = "us-central1"
19+
}
20+
```
21+
22+
## Argument Reference
23+
24+
The following arguments are supported:
25+
26+
* `name` - (Required) The name of the regional backend service.
27+
28+
* `region` - (Optional) The region where the backend service resides.
29+
30+
* `project` - (Optional) The ID of the project in which the resource belongs. If it
31+
is not provided, the provider project is used.
32+
33+
## Attributes Reference
34+
35+
In addition to the arguments listed above, the following attributes are exported:
36+
37+
See [google_compute_region_backend_service](https://registry.terraform.io/providers/hashicorp/google/latest/docs/resources/compute_region_backend_service) resource for details of the available attributes.
