Envoy Internals Deep Dive - Matt Klein, Lyft (Advanced Skill Level)
Envoy (www.envoyproxy...) is a high performance L4/L7 network proxy with a pluggable filter chain model; this allows Envoy to be used for a variety of different scenarios, including HTTP/2, gRPC, MongoDB, and Redis. Envoy provides advanced load balancing support, including eventually consistent service discovery, circuit breakers, retries, rate limiting, and zone-aware load balancing. Envoy also has best-in-class observability, using statistics, logging, and distributed tracing. Since becoming OSS in 2016, Envoy has gained substantial traction in both "service mesh" and edge (API gateway) deployments. In this talk, Matt Klein will dive deep into Envoy internals from a systems perspective, covering threading model, stats, hot restart, the xDS APIs, and other core concepts. This is an advanced talk and prior knowledge of what Envoy is at a high level is assumed.

"if blocks you, you're basically fucked " I love this talk!!!!!

[@DatNguyen-ry1vr]

Impressive technical presentation !!

[@mangeshbharsakle5847]

Awesome !! He talks like he has uploaded the Linux Operating system and Envoy source code into his Brain 😀

[@eyaswoo1483]

Can I say, the core of envoy is a L3/L4 proxy? All other features or functionalities are built upon this base.

[@krishnakantchaurasia269]

That was a great and very informative talk, if possible can you please share the presentation slides ?

[@mnlnl65091]

Great talk!

[@quiubolecab]

Matt at the beginning of the talk you said that maybe C++ was not the best language decision for envoy. What would be a better choice at this moment? Great talk.

[@jorshaw86]

Rust provides similar performance characteristics but much more modern language. Go isn't bad either but if optimizing for perf Rust would be the next obvious choice.
