xDS Support in gRPC

CNCF [Cloud Native Computing Foundation] via YouTube

Overview

Explore the integration of xDS support in gRPC in this 23-minute conference talk by Mark D. Roth from the Cloud Native Computing Foundation (CNCF). Delve into the evolution of xDS APIs from Envoy's control plane to a Universal Data Plane API (UDPA) for configuring various data plane clients. Discover the advantages of xDS support in gRPC, particularly for service mesh deployments, and learn about current and future xDS features in gRPC. Examine the changes made to the xDS data model to accommodate non-proxy clients like gRPC, and understand the edge cases addressed in the xDS transport protocol. Gain insights into how control plane operators and vendors can support gRPC xDS clients alongside Envoy, and explore topics such as API listeners, client caching behavior, resource unsubscription, and potential challenges. Conclude with a roadmap for future developments and key considerations for xDS server implementation to support RPC effectively.
