Scaling and Securing WebSockets with HAProxy

WebSockets technology is a bidirectional, full duplex protocol for communication between client and server over the web. It has been standardized in 2011 and its fully compatible with HTTP. This protocol enables realtime applications such as chatting, notifications, live feed , multiplayer gaming and otheruse cases.
In this Video I want to discuss websocket secure protocol wss:// which is done over TLS on port 443

There's something about the way you explain things that make it easier to understand. The additional impressions in your voice is great. Thanks for the video. Additionally, what sort of problems do web sockets solve?

[@hnasr]

uchenna nwanyanwu ❤️ thanks for your message appreciate it. Web sockets solve the problem of bidirectional communication (server sends info to the client without requesting) such as chatting, gaming etc.. check this video : The good, the bad & the ugly of WebSockets kzbin.info/www/bejne/enfPmKyohZp7g7s

Very good explanation, hope I can get wss working on an EC2 instance in AWS now. Keep it always as simple as that. Thanks! =)

[@hnasr]

Fabiano Jardim thanks! It should be easier on an EC2 instance you dont have to do all the goofy port forwarding stuff that I did. Let me know how it goes!

[@stevenalves7506]

Greate video, thank you!

Great video, from my understanding, HAProxy falls back to L4 loadbalancing. Is the TCP data "ssl decoded" by HAProxy then forwarded to backend in the same TCP connection ? is it or not a TCP connection from HAProxy to pods so that HAProxy could only established 65k connection to each pod ?

Thanks for this video!

It will be helpful to have a tutorial about Scaling and Securing Web Apps with HAProxy Community Edition as WAF - Web Application Firewall with ModSecurity 3.0

[@nikogenia]

Thank you! Good video!

Here if we use the L7 load balancer eventhough the HA proxy may maintain the NAT ing in the load balancer side to forward all request coming from one client to same server, won't L7 LB create an another tcp connection to forward the request.

[@hnasr]

Singaravelan N correct, Haproxy falls back to layer 4 and streams to the backend

[@singaravelann3671]

You mean eventhough we mention L7 load balancing here it will fall back into L4 loadbalancing ??

[@singaravelann3671]

Hussein, Thanks a lot for replying me, this is the proof for the same 'www.haproxy.com/blog/websockets-load-balancing-with-haproxy/'

[@old9]

seems that the sendevery5seconds messages are adding up after several connections

[@alshameerb]

You are simply super

[@khayryazzez]

How can i direct the client to the room of other client when using a round robin Algorithm ?!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

[@vivamedia5958]

Where is the link to previous video Dear Hussain? :)

[@Oswee]

gRPC is for interservice communication or native apps. There exists grpc-web... but due to performance degradation i would not to use it in browser. And... technically you didn't fully secured your ws traffic. In LAN it is still insecure, i believe. :) But... nice vid! :) :)
