Using microservices to solve real-world problems always involves more than simply writing the code. You need to test your services. You need to figure out how to do continuous deployment. You need to work out clean, elegant, resilient ways for them to talk to each other.
A really interesting tool that can help with the “talk to each other” bit is Lyft’s Envoy: “an open source edge and service proxy, from the developers at Lyft.” (If you’re interested in more details about Envoy, Matt Klein gave a great talk at the 2017 Microservices Practitioner Summit.)
Envoy Overview
It might feel odd to see us call out something that identifies itself as a proxy – after all, there are a ton of proxies out there, and the 800-pound gorillas are NGINX and HAProxy, right? Here’s some of what’s interesting about Envoy:
- It can proxy any TCP protocol.
- It can do SSL. Either direction.
- It makes HTTP/2 a first class citizen, and can translate between HTTP/2 and HTTP/1.1 (either direction).
- It has good flexibility around discovery and Continue reading
