Internal TCP/UDP load balancer and Service Directory overview

You can choose to automatically register your internal load balancer service with Service Directory when you create an internal load balancer. This enables client applications to use Service Directory through HTTP, gRPC, and/or DNS to resolve the address of the internal load balancer service and connect to it directly.

Registering your internal load balancer with Service Directory lets you do the following:

  • Choose custom DNS names to serve the network locations of your internal load balancers as opposed to DNS accessing your internal load balancer only through an internally-generated DNS name in the .internal domain.
  • Serve multiple internal load balancers from the same DNS domain name, which is otherwise not possible with the current auto-generated DNS records.
  • Register internal load balancers directly and automatically in Service Directory providing a single repository for all your services in Google Cloud.
  • See standalone services, endpoints, and your internal load balancer endpoints with a single command in the Service Directory API.
  • Apply administrative actions like access control to Service Directory resources at the namespace or service level to encompass both your internal load balancer endpoints as well as other backend services.
