* Background: A managed instance group of workers is used in backend services for global load balancing (HTTP/HTTPS Ingress) and output for custom global load balancing use cases * Add worker instances to a target pool load balancing TCP/UDP applications (NodePort or proxied). Output as `worker_target_pool` * Health check for workers with a healthy Ingress controller. Forward rules (regional) to target pools don't support different external and internal ports so choosing nodes with Ingress allows proxying as a workaround * A target pool is a logical grouping only. It doesn't add costs to clusters or worker pools
