Envoy Proxy Crash Course, Architecture, L7 & L4 Proxying, HTTP/2, Enabling TLS 1.2/1.3 and more



Envoy is an open-source L7 proxy and communication bus Originally built at Lyft to move their architecture away from a monolith.

In this video, I want to go through the following

* What is Envoy? 0:00
* Current & Desired Architecture 0:48
* Envoy Architeture 3:00
* DownStream/Upstream 7:30
* Clusters 9:19
* Listeners 10:50
* Network Filters 11:50
* Connection Pools 13:45
* Threading Model 18:34

* Example 21:25
* Show the 4 apps 24:30
* Install Envoy Brew 26:00
*
* Envoy as a Layer 7 Proxy 27:30
* Proxy to all 4 backend NodeJS services 28:00
* Split load to multiple backends (app1/app2) 40:00
* Block certain requests (/admin) 45:30
* Envoy as a Layer 4 Proxy (tcp router) 47:50
* Create DNS record 54:00
* Enable HTTPS on Envoy (lets encrypt) 55:30
* Enable HTTP/2 on Envoy 1:03:00
* Disable 1.1/1.0 Enable TLS 1.2 and TLS 1.3 ONLY on Envoy 1:04:30
* SSL Labs test 1:06:40
* Summary 1:07:24

  1. If you liked these deep dives into proxies and other backend tech hit that like button and subscribe for more. Do suggest what should I discuss next 👇🏽

  2. In my company, we write python scripts to generate yaml configs which're eventually used by nginx/envoy, this is much more enjoyable to write and less error-prone

  3. No you dont ssh into the container, you can customize by creating a new dockerfile and build or use runtime env files. You should look at containers.

  4. I wanted to use envoy in case of outbound. just for forwarding. but envoy replied "no healthy upstream". I don't know how to make it.. I want to use envoy just for proxy to outbound(variable address, not static like inbound). anyone help me plz!! I already made inbound Architecture with lb. but outbound is not yet….

  5. I'm trying to understand what you mean about the threading model and its not truely load balanced? If its useing native threads or LWP in Linux it still uses multiple cores if available. In fact its more efficent then forking which has to copy the stack, heap.
    With LWP you can share the same memory space but create a seperate execution thread. Perhaps your thinking about Pythons threading model which is Green Threads and not Native threads? Green threads are not the same as OS threads. Green threads are managed in userspace and not at the OS level. Ruby, Python have a GiL which is why they will proably be never have native threads. Thats why its more desireable to Fork then Thread in those languages. A C++ program with native threads will beat a forked Python, Ruby script any day.

  6. Even I hate YAML, can you come up with a better markup language? Or if you have an idea, we can work together – github id – sacOO7

  7. Thank you, till literally your video I didn't get the core concept I suppose, new to the field it just all felt a bit 'you either know it all or just dont' and it made approaching learning difficult as people dive right in to some complicated niche bit of it and gloss over what they assume you already knew which may well be nothing, so i was left lost in many cases. You've really helped me here, thanks 🙂

  8. Hi Hussein, great video!
    One question about the multithreaded issue with load-balancing – Why does this only happen with TCP and not with the HttpConnectionManager? Shouldn't the multi-threaded issue still exist for L7 since a different thread is picking up the request each time?

    Thanks again!

  9. solo.io recently had several sessions about Envoy. They are really great. If anyone wants to dive deeper, please refer to this link: https://www.youtube.com/c/soloio_inc/search?query=envoy

  10. Hi ,Could you please put video or any link, how to use envoy mysql proxy (select command go to read DB and rest of all liek insert,delete etc etc go to RW DB). Thanks in Advance

  11. This was a great watch. Your enjoyment and attitude towards this made it really refreshing. You made the concepts easy to understand and follow. Looking forward to your next videos.

  12. Great job. Going through proxies one by one gives us cool overview of the landscape. Caddy2 video would be awesome 😉

  13. Man, what about copying the whole line, including the whitespace. Then paste it on the first column, so you are sure to keep the same number of spaces. Great video btw

  14. This was very deep and a really great introduction for beginners thank you for putting it together. 2 questions, what would a general architecture look like with Envoy if you were using this as an internal load balancer for Microservices that receive heavy internal load (I.e. from other services) and 2) when are you going to do a live stream?!!

  15. Today I’ve found this page that explains how to configure Envoy as an edge proxy: https://www.envoyproxy.io/docs/envoy/latest/configuration/best_practices/edge#best-practices-edge

  16. Hi Hussein, Thanks for the awesome demo! I have little knowledge about proxy settings, so a bit confused by your infra setting, 1. are you running envoy and app server both on your Mac? Because I see you run certbot locally…and 2. do you configure your browser and curl to use envoy as a proxy, otherwise how do they be aware of it? Thanks!

  17. YAML for docker and kubernetes it's very readable, but use for configuration like envoy………….man! really like be tortured!

  18. i love your content but why you don't start making arabic content as arabic content is very weak and need videos like your awesome videos … anyway keep going❤️❤️

  19. Thanks for the video! To get HTTPS on a server, is there any difference between having an HTTP server behind an HTTPS proxy or having an HTTPS server directly?
