/**
 * Creates and manages Scaleway Load Balancer backends.
 *
 * or more information, see the [main documentation](https://www.scaleway.com/en/docs/network/load-balancer/reference-content/configuring-backends/) or [API documentation](https://www.scaleway.com/en/developers/api/load-balancer/zoned-api/#path-backends).
 *
 * ## Example Usage
 *
 * ### Basic
 *
 * ```typescript
 * import * as pulumi from "@pulumi/pulumi";
 * import * as scaleway from "@ediri/scaleway";
 *
 * const backend01 = new scaleway.LbBackend("backend01", {
 *     lbId: scaleway_lb.lb01.id,
 *     forwardProtocol: "http",
 *     forwardPort: 80,
 * });
 * ```
 *
 * ### With HTTP Health Check
 *
 * ```typescript
 * import * as pulumi from "@pulumi/pulumi";
 * import * as scaleway from "@ediri/scaleway";
 *
 * const backend01 = new scaleway.LbBackend("backend01", {
 *     lbId: scaleway_lb.lb01.id,
 *     forwardProtocol: "http",
 *     forwardPort: 80,
 *     healthCheckHttp: {
 *         uri: "www.test.com/health",
 *     },
 * });
 * ```
 *
 * ## Import
 *
 * Load Balancer backends can be imported using `{zone}/{id}`, e.g.
 *
 * bash
 *
 * ```sh
 * $ pulumi import scaleway:index/lbBackend:LbBackend backend01 fr-par-1/11111111-1111-1111-1111-111111111111
 * ```
