Dial Once, Scale Infinitely - Production-Ready gRPC Without the Mess

Learn how to build scalable gRPC interactions in production microservices environments through reusable client abstractions, type-safe interfaces, and custom service discovery mechanisms in this 21-minute conference talk. Discover how to design systems that use shared client-creator abstractions to centralize gRPC setup, connect through custom endpoint discovery services for dynamic resolution, and leverage auto-generated typed clients to enforce strict service contracts. Explore the "dial once, use many" model for managing long-lived gRPC connections while avoiding common pitfalls like calling unimplemented methods or creating redundant dials. Gain insights from real-world production experience where this approach was successfully deployed for hundreds of thousands of users, making this presentation particularly valuable for backend engineers and platform teams seeking to simplify gRPC usage while maintaining strong boundaries and performance.
