• appreciate your work thanks a ton

  Great Video.

• Loved this!

• Incredible efforts! to be honest i am truly grateful to find this channel ! keep up the good work! thank you so much

• It is so easy to study for my system design interviews when I have so much quality youtube to click through, quite lazily I might add. Thanks for the amazing videos!

• It was a nice video, but it barely explained "How Web Sockets work", only in 3:45 to 4:18.
  Almost all of the video was actually about "What are Web Sockets", focusing mainly on a comparison between polling and sockets, which was well presented, but wasn't supposed to be the topic of the video promised by the title.

• As others have said, this is some of the best content on YouTube. Could you do a complete course on K8S? I’d happily pay for it

• But you haven't explained how it works. Not even a bit. Like what is behind those well-known WS interfaces? What is in the TCP package? Is it any special for WS? Do we need a URL to establish a connection? How to distinguish one connection from another one? Is there a notion of a cookie? How does the session work in the context of WS-based service? How does load balancing work with WS connections? What is the usual limit on the number of WS connections? Is it a number of opened file descriptors? What it depends on?

• excellent👍

• Who asked you about polling
