gRPC is a high-performance RPC framework built on top of the protobuf serialization/deserialization library popularized by Google. There are gRPC bindings for many programming languages, and the efficiency of the protobuf parsing as well as advantages from leveraging HTTP 2 as a transport make it a popular RPC framework for those building new microservices from scratch. This episode of Cloud Native Livestream will cover how to use Cilium to enforce gRPC-aware security policies.
