Envoy Proxy 의 성공 모델이 뭔지 궁금해서 잠깐 찾아보았는데요,

https://clutch.sh/docs/about/what-is-clutch
Clutch has patterned itself off of the successful model used by Envoy Proxy, also developed at Lyft, offering a rich, configuration-driven alternative to legacy tools. Deploying Clutch is also dead simple, with a single binary for both frontend and backend.

이런 식으로 기재되어 있는데 Envoy 의 성공적인 모델이라는게 많은 것을 설정할 수 있도록 한다는 이야기인 거겠죠...?
