You are deploying a global API service that uses gRPC for communication. Clients are located worldwide. You need a load balancing solution that provides a single Anycast IP address, terminates TLS, and routes traffic to the closest healthy backend region. Which load balancer should you choose?

The Global External HTTP(S) Load Balancer is a Layer 7 load balancer. It natively supports gRPC traffic (which relies on HTTP/2). It provides a single Anycast IP address, allowing clients worldwide to connect to the closest Google edge point of presence, where TLS is terminated, and traffic is routed over Google's premium backbone to the nearest healthy backend.
