Envoy as TCP proxy
Envoy from scratch: why it's useful, how to use it, few use cases and accent on TCP level. Overview for the few deployment types: service-to-service, service-to-service with front proxy and double proxy. May be usable for DevOps Engineers who are interested in CNCF modern services or not happy with HAproxy. I will share our experience how we deployed Envoy as proxy for key-value storage in unsecured distributed network with hot-restart without dropping connections.
