Application Load Balancers enables gRPC workloads with end to end HTTP/2 support
Application Load Balancer (ALB) now supports gRPC protocol. With this release, you can use ALB to route and load balance your gRPC traffic between microservices or between gRPC enabled clients and services. This will allow customers to seamlessly introduce gRPC traffic management in their architectures without changing any of the underlying infrastructure on their clients or services.
