The Journey of an HTTP request to the Backend | Backend Engineering Show

In this episode of the backend engineering show, I explain the journey of an HTTP request that gets initiated from a click on a link. I discuss DNS, TCP, API Gateways, reverse proxies, load balancers , backend web servers, and much more.

[@razorr1920]

I did join your course on Udemy. Bought almost all of them without giving a second thought or stars ratings on udemy. I really enjoy your content. Used to be a Flight Engineer in the past but my passion for tech moved me back to the world of mysteries. Just one request. Pls post your videos with a smily face thumnail.... that helps a lot... Cheers mate.🤗

[@amitkumargupta-]

Bought already, will go through soon. I'm a front-end developer with curiousity to know more about these backend stuffs.

[@jacksparr0w300]

Awesome! I was looking for a book on nginx two days ago. Ill picked up this Udemy course in meantime.

[@nontraditionaltech2073]

Hussein, you’re my favorite! Even though I’m 41, I wanna be like you when I grow up 😎

[@VishnuVijai_]

😂

[@roumakchakraborty3407]

+1 to that, Although me Im 25

[@Muaddibkhan]

amen to that

[@pragmaticindianenginner5585]

Hey Naseer, I've been watching your videos for quite some time now. I have to say that this channel is undoubtedly one of those which has the actual software engineering content. I love the way you dive deep into the details and do a detailed analysis of the outage, vulnerabilities etc. I learn a lot from you dude. A big thank you to from my side for delivering such amazing content. You're one such person whom I actually look up to. Thanks a lot. Keep making such videos.

[@khaledmaruf5813]

Hi Hussein, Your videos are great and pretty descriptive, but I think It'll be nice if you sometimes if you show some slides with some drawings as you verbally elaborate the parts. That'll help at least some of us to follow easily :) TIA

[@adarshk9057]

Thats why its called podcast

[@Varun2799]

Yours is the only youtube channel where I have bought the membership to because the value of the knowledge you provide is 10000x what the membership costs and I will continue to be a member so you can hopefully pump more videos out Thank you

[@hnasr]

Thank you for the support ❤️

[@curiossoul]

Wow. A few millis round trip is so complex that it took 36 minutes to walk through its flow. I feel this is also a brilliant summary of your Networking course, several concepts were referred to in the talk. Thank you 🙏

[@SaifurRahman92]

It will be interesting to watch all these parts practically in a local machine! Great video Nasser!

[@jimjuma7916]

I listen to this as a podcast. Absolutely love it.

[@lakhveerchahal]

This is a very interesting area to talk about. Networking! Would love some practical videos on this topic too. Much love as always ❤️

[@michas7993]

Gest job Hussein! Recently I bought two of your courses. I hope that more courses regarding backend programming will be released soon 😀

[@ramshankarkumar4222]

Amazing detailed talk. Thank you for this talk !!! Love your content.

[@michaelangelovideos]

You’re amazing man. Please keep this content up🙏

[@adityasethi9794]

You're a genius. Is there a way to work with you? Like I'm a software developer and I would definitely love to work with you. The passion you have to understand these technologies in detail is just amazing and so damn inspiring. Really think you're the best on KZbin.

[@nicolasgomez5207]

this guy is a 500k a year SWE, anyone would hire him

[@hargunbeersingh8918]

@@nicolasgomez5207 not 500k, probably more. He is a principal engineer and that is usually the third highest swe rank in most companies. I dont think that Esri has distinguished engineers and fellows so I assume he already has the highest swe rank in the company. I assume that he is a 850k+ SWE

[@devguyahnaf]

@@hargunbeersingh8918 Hm

[@geekofia]

These talks are fascinating ❤️

[@cacurazi]

Too complicated for me. I need to go back to study the basics... Your knowledge is much appreciated Hussein. Thank you!

[@ASHERJK98]

Rightt, need to circle back to this video after watching the basics

[@rajivharlalka]

Hey Nasser, Really Love your videos. Could you also add some reference links to topics on which you speak where more detailed content can be accessed. Would be helpful on getting into depth on these topics 😄

[@LyadhKhorEngineer]

Thanks for this amazing content.

[@hnasr]

You are welcome!

[@ahmedtawil7705]

Nice show Hussein , what about the next topic you talk about smtp and how mail server work and the basics of email ❤️

[@tubenzr]

Nice Topic Bro.. 👍👍👍 I'm all ears

[@momedalhouma14]

Great, would be nice if you make a video about encoding and how the http messages are transmitted over the wire, which component does the encoding....

[@theSDE2]

Thanks SIr for sharing the details here. Really learnt about alot of things watching this that i didnt knew if existed. Will checkout the udemy course as well. Is there any other resource such as blog or book which you recommend to know more in details

[@krishnasumanth007]

That expression you gave after the phrase "unless you're a chinese laptop" 😄

[@khanriza]

This sounds like a sermon you'd hear at friday prayers.

[@abhay626]

Amazing!

[@kamalhm-dev]

Hussein, great content. But please keep it focused on the content. For example, when you're talking about http2, you'd digress to saying things about http3 which made your story harder to digest

[@anischihi1280]

Excellent 👍

[@developerscorner5987]

You should start a podcast with a voice like that Hussein :p

[@developerscorner5987]

oh my bad, you do have a podcast XD

[@nitishbhatia25]

Wow. Awesome.

[@hnasr]

🙏

[@dickvanfreedman]

Can you make a video on live web-socket connection? With all this happening with one single http/https request, that request is still less expensive than maintaining a live connection.. want to know how come....

[@seekspire]

Hello , Can you create a video with a diagramatic representation which shows what you are saying. Actually it's going bouncer

[@susmitvengurlekar]

So deep !

[@Suraj-qs7nj]

Bought, thanks

[@tisurmaster]

It would have been nice if we had some visual for those not strong in this knowledge.

[@juliuslehmann5468]

Nice video

[@thelostrider1]

What do you mean by sending a request that sends 8 commands in a single byte? You should have expanded on that (or give some reference where people can look up), that sounds a bit weird: how is it possible to send 8 commands with 1 byte since normally you need 1 byte to represent 1 char (depending on encoding, etc..)?

[@LeMustache]

Why would you need to encode characters? Simply program your backend to interpret each bit set to 1 as a command that says "execute the instruction under that bit". Hell, if one request can execute only one command at a time you could fit 256 instructions into a single byte.

[@thelostrider1]

@@LeMustache Hmm, yeah take makes sense. For each number give a set of commands. Do you have any reference for that? Would like to see how that could be done

[@widyguilias3738]

do you learn blockchain? if you do, can you make video about blockchain fundamental? thanks

[@prateek2159]

If the video title says," "HTTP" request" then why did the request go to port 443 ?

[@anonymousmangalorean]

Yo man try using a white board next time. This is interesting!!

[@JaneDoe-od4ep]

What's wrong with fps on this video? I believe it barely hits 20 frames per sec or something close

[@aparnasarkar7744]

Unless you're a Chinese laptop cracked me up :D

[@hsngsoftware4380]

How many ports are there in computer

[@atraps7882]

I wanna be like Hussein when I grow up

[@yashgaur9619]

"Unless you are a chinese laptop" 🤣 Why do you do them like that?

[@VivekYadav-ds8oz]

You never really _presented_ anything this video. It was wayyy too high-level to contain anything interesting/useful.

[@akhileshvatupalli]

Your videos are not interactive. You keep on talking. You are knowledgeable, but it is not helpful 💯 %

[@syedkamranahmed4854]

Hi Hussein, Could you please send the link of your discord server?
