This advanced session shows how Gama (go-gRPC+Homa+Http3) implements high-performance gRPC in Go over raw Homa while also supporting HTTP/2 and HTTP/3 on the same service port. We will walk through architecture decisions, transport internals, TLS design (including Homa TLS 1.3 flow), and benchmarking patterns for unary and bidirectional streaming workloads. Through real user stories and case studies, we will cover what worked, what failed, and what changed in kernel, networking, and app layers to get reliable low-latency behavior. Attendees will leave with practical guidance to evaluate, prototype, and operate alternative RPC transports without abandoning existing gRPC service contracts.

This demonstrates how high-performance gRPC can be delivered in Go using Homa, while maintaining compatibility with existing HTTP/2 and HTTP/3 services on a single endpoint. This session explores the architecture, transport design, TLS integration, benchmarking approach, and operational lessons learned from building and deploying an alternative RPC transport. Attendees will gain practical guidance for evaluating, prototyping, and operating low-latency gRPC transports while preserving existing gRPC APIs and service contracts.
