AWS Next Generation Load Balancing: ALB with gRPC and HTTP/2
AWS announced an important update for the Application Load Balancer (ALB) in November 2020: Support for gRPC and HTTP/2.
HTTP/2 comes with request multiplexing over a single TCP connection, header compression (HPACK) which reduces network utilization, and a
binary protocol which reduces overhead in parsing data.
gRPC is a high-performance RPC framework with full-duplex streaming. It is designed to connect mircoservices efficiently and uses HTTP/2 under the covers.
This video includes a demo of a gRPC service running behind an ALB.
