At first glance, this is “just another protocol” running over TCP/HTTP. But working with gRPC load balancing can be a bit tricky as you have to use a different set of tools for testing (e.g. grpcurl instead of curl), the return codes are different and things like unary calls vs. streams require a good understanding of the protocol and its implications. We will give an overview of the protocol, explain what load balancing options we have using examples of AWS Load Balancers. We will explain how to perform functional and performance testing and finally go through some common pitfalls when Load Balancing gRPC. ## Speakers ### [Max Hausner](https://www.wearedevelopers.com/@max-hausner) Max Hausner, Solutions Architect at Amazon Web Services ### [Yves Fauser](https://www.wearedevelopers.com/@yves-fauser) Specialist Solution Architect Containers at AWS ## Related talks at this congress - [A Deep Dive on How To Leverage the NVIDIA GB200 for Ultra-Fast Training and Inference on Kubernetes](https://www.wearedevelopers.com/events/world-congress-2025/sessions/538-a-deep-dive-on-how) — Kevin Klues - [RPC Reinvented: Asynchronous, Durable, and Agent-Ready](https://www.wearedevelopers.com/events/world-congress-2025/sessions/500-rpc-reinvented) — Maxim Fateev - [High performance Serverless Java on AWS](https://www.wearedevelopers.com/events/world-congress-2025/sessions/623-high-performance) — Vadym Kazulkin - [Azure-Well Architected Framework - designing mission critical workloads in practice](https://www.wearedevelopers.com/events/world-congress-2025/sessions/622-azure-well) — Paweł Siwek
