 * Represents a Health Check resource.
 * Google Compute Engine has two Health Check resources:
 * * [Global](/compute/docs/reference/rest/{$api_version}/healthChecks) * [Regional](https://cloud.google.com/compute/docs/reference/rest/{$api_version}/regionHealthChecks)
 * Internal HTTP(S) load balancers must use regional health checks (`compute.v1.regionHealthChecks`).
 * Traffic Director must use global health checks (`compute.v1.HealthChecks`).
 * Internal TCP/UDP load balancers can use either regional or global health checks (`compute.v1.regionHealthChecks` or `compute.v1.HealthChecks`).
 * External HTTP(S), TCP proxy, and SSL proxy load balancers as well as managed instance group auto-healing must use global health checks (`compute.v1.HealthChecks`).
 * Network load balancers must use legacy HTTP health checks (httpHealthChecks).
 * For more information, see Health checks overview.
