Accelerating Envoy with the Linux Kernel - Thomas Graf, Covalent (Advanced Skill Level)

This talk will provide an introduction to injection options of Envoy and then deep dive into ongoing Linux kernel work that enables injecting Envoy while introducing as little latency as possible. The servicemesh and the sidecar proxy model are on a steep trajectory to redefine many networking and security use cases. This talk explains and demos a new socket redirect Linux kernel technology that allows running Envoy with similar performance as if the sidecar was linked to the application using a UNIX domain socket. The talk will also give an outlook on how Envoy can use the recently merged kernel TLS functionality to gain access to the clear text payload transparently for end to end encrypted applications without requiring to decrypt and re-encrypt any data to further reduce the overhead and latency.
