What happens before the Backend gets the Request

When we send a request to a backend most of us focus on the processing aspect of the request which is really just the last step.
There is so much more happening before a request is ready to be processed, most of this step happens in the Kernel. I break this into 6 steps, each step can theoretically be executed by a dedicated thread or process. Pretty much all backends, web servers, proxies, frameworks and even databases have to do all these steps and they all do choose to do it differently.

Finally, someone who's going beyond just explaining the API of the libraries! Don't stop man, you're making great content!

I see lot of YouTubers just scratch the surface and people comment you are the best.
I like how thorough and detailed explanation you do.

[AdekunleLawal]

So happy the algorithm brought this channel my way. Love the deep dives Hussein does 👏🏽

[shalabyx]

Amazing walkthrough 👏 I can’t imagine how this would look if you explain all this steps by using one use case! Anyway it’s just amazing 🌹

Just last week we were doing an assignment on how to create a client-server architecture for a simple program That echo the requests from the client using sockets.
We were using the c programming language and it was really interesting to learn how actually a server listens and accepts request and how it forks so as a to handle different clients while at the same time listening.
This was what i needed to reinforce what i learnt and i felt really proud that i was actually understanding some concepts you were talking about.
Im just a beginner in this field but i have so much fire and curiosity about the backend. I totally enjoyed this.!!❤

This is like ASMR which makes you think and imagine! Wow!

Watching this I released more dopamine than watching a Netflix movie. ♥

Your channel is a gold mine of information

[shyampramanik]

This is GOLD !! Thanks Hussein for this amazing content.

[abdullahclementabdulshekur]

I'm transitioning into backend from frontend and i wanted to learn and understand high and low level concept before building projects. and your courses have been very helpful. The netowking, backend and database engineering concepts.. have been really helpful to me. I do have a request though, a course on systems design would be great. Keep doing the good work..

[ahmetyasarozer]

Perfect content, as usual. Thanks Hussein <3

[gustavodeoliveira]

you are a game changer.
thanks for that man

[mauriciotamez]

There is so much knowledge here. ILYSM Hussein <3 thx for the great content as always

[okfxklf]

This is by far the best thing on internet!
you're amazing!

[prateek]

I missed your long videos. This one was a fab. Please keep making more such videos

[cumbi-mongo]

Great content as always! Thanks a lot.

bro is in love with computer science :)

To anyone watching this, I purchased and am partway thru 3 of Hussein's Udemy courses and they're great! Same quality walkthroughs but on a much wider variety topics.
Only feedback would be: more evenly timed videos (some are 50mins..) and less digression off-current-topic.

Couldn't imagine these process in containerized environment :)
