DTR does not provide a load balancing service. You can use an on-premises
or cloud-based load balancer to balance requests across multiple DTR replicas.
> **Note:** If you also use UCP there are [additional requirements](https://docs.docker.com/ee/ucp/admin/configure/join-nodes/use-a-load-balancer/#load-balancing-ucp-and-dtr) if you plan to load balance both UCP and DTR using the same load balancer.
You can use the unauthenticated `/_ping` endpoint on each DTR replica,
to check if the replica is healthy and if it should remain in the load balancing
pool or not.
