Great Video! I have one question though. I did not quite get why HTTP does round robin but TCP doesn't? You mentioned something about browser opening a connection and reusing it. But I did not quite get it since I am not well versed with protocols and their nitty gritties.

[@dineshrhel7898]

What a great presentation and entertaining flow, he has extraordinary skills in teaching

[@tharunshiv8799]

You are doing an amazing job with these topics!! That we never find anywhere! You are awesome. Thank you again.

[@alphabanks]

This was an amazing video I like how you started with a basic config and built up from there. Most videos start with tons of lines in the config file with zero explanation.

[@reymartbetana3481]

Wow very easy to catch-up and it's never boring to watch at the same time. Coolio! Many people really needs this kind of presentation. Thanks

[@martinbozinovski]

You 've just connected a lot of stuff that was unclear for me. Genius tutorial, love it!

[@emmanuelyeboahmanu8789]

This is the most detailed and understandable deep dive into haproxy and ssl certification for the domains I've ever loved. This has helped me in my software engineering project. Thank you Boss Hussein Nasser. Kudos

[@michaeldorsey8836]

I enjoyed watching this video so much. I never comment on videos but since this is my first time watching you I had to tell you how great you are. Keep making videos like this and expanding people's knowledge.

[@hnasr]

Michael Dorsey thank you so much Michael for taking the time to leave a heartfelt comment I appreciate it so much! 😊

[@purposepowerlove]

Fantastic video! I love how clear, concise, and excited you are.

[@mlestat2003]

Great video Nasser, Loved every explanation of it. Thanks for making and sharing the knowledge! Kudos to you.

[@joeyr9876]

Amazing video! I need to stand up HAProxy where I work, and have never used it before. Now, I feel like I have enough knowledge to get going!

[@user-fx9gg2bw1n]

Hussein, you are a marvelous teacher. Your sense of human is another addition to your teaching capabilities ! I enjoyed it a lot ! Still 2 items are missing, SSL termination and creating a loadbalancing pair. Still without what you learned me, I wouldn't be able to understand those additions. I shared this video !

[@pjarrett2028]

Extremely detailed, but easy to understand, and FUN. Thanks for making this video!

Hey @Hussein Nasser,
Great video. Loved the whole content. Actually viewed it 2nd time after more than a year. Still loved it.
I don't know somehow your resources link doesn't work for haproxy and certbot.
Also, it would be great to watch if you could make a video or extension of it for tcp load balancing without tls termination using haproxy.
