Hi Friends, I am Anshul Tiwari and welcome to our youtube channel ITkFunde.
About this video -
In this video, we will understand the basics of proxy servers and how it is different from a reverse proxy server. This video will explain the meaning of proxy and how a proxy server
While proxy servers help protect client machines from an outside network, a reverse proxy does the exact opposite of securing servers from outside networks.
Using proxy servers offers the following advantages:-
1) Enhanced Security
2) Better Performance
3) Load Balancing
4) Compression
5) Encryption and Decryption

frankly my mom in my youth was a firewall blocking all requests for toys and opened the ports to the toy store only on my birthday

I love the use of the parent-child relationship as an analogy for the proxy server.

[@ITkFunde]

Thanks Eric for your comment. Just tried to simplify complex stuff. Do checkout our other 19 tutorials on Google cloud and other technology. Cheers Anshul

[@Jan_Seidel]

I don't know no better way to explain it to someone who is not into IT :)

[@aaronliu4924]

A quick summary from the video of the PROS part on a proxy:
1. Firewall.
2. Better management.
3. Security.
4. Caching.
5. Encryption/Decryption.
*Reverse proxy protected server, instead of clients.
Additional PROS
1. Load balancing the traffic. (Reverse proxy can have/be a load balancing feature, but it's not necessary.)
2. Caching (inherited from the proxy, but thinking in a reverse way).
3. IP musk (inherited from the proxy security, but thinking in a reverse way).
4. Compress the request size (zipping request). Save more bandwidth for performance.

[@ITkFunde]

Thanks Aaron hope you could add your valuable feedback in future as well

[@mydemon]

I don't use this word easily, but the example with the parents being proxies is absolute genius.

[@ITkFunde]

Thanks a lot

[@luqmanfuadmuhasadz8736]

yeah i agree

[@MB-jz4wq]

Whoever was your teacher or taught you about IT turned you into a Master! Thank you for your humility, simplicity and generosity in teaching. Continued success and elevation to you😊

[@ITkFunde]

So nice of you

[@irfanshaik1302]

what a nice way to compliment someone 👏

you solved my 10 hour confusion in 10 min!! cheers!

Thanks Pallav your comment made my day. Pls Keep supporting !!

[@VPannagS]

In a nut shell:
Proxy isolates clients from internet
Reverse proxy isolates servers from internet

[@RakibCan]

Your analogy with parent-child was a great example to get the ball rolling. Thanks for the video.

[@Hostlyy]

This guy explains everything very well. Today I learned stuff that I could never understand in a couple of minutes

[@poornanilkund9371]

How I wish I had access to such great content during my engineering years!

[@ITkFunde]

Thanks Poorna 🙏☺️

[@wasifalam545]

Thank you for clearing the concepts witin just 10 mins.

[@sandygodu007]

I always had difficulty understanding these two concepts but you have simplified them using real-life examples. Thank you so much.

[@ITkFunde]

Thanks Sandeep

[@rindia84]

No comments will be enough to express my compliments! Great lecture, easy style of presentation. I'll share with my office junior team members. I wish you please publish some AWS step-by-step videos at later dates (especially the networking part - if this ever comes in your work area).

[@margento60]

I've learned so much from you! Thank you, and keep them coming (please)!

[@igordolvich9235]

Thanks, this really helped to clear some things up and refresh my memory on this topic. In particular, your example/analogy with kids and their parents acting as a proxy to the outside world was brilliant - very intuitive and easy to understand, helping one better grasp and remember this concept. I wish I had a teacher like you back in my university years.

[@ITkFunde]

Thanks Igor means a lot !!

[@coldCoders]

You know this is genuine teaching when you do not see advertisements or sponsors.. Love your teaching

Never thought I would be learning this thank you ❤🧡💚💙💜

Dude, that was amazing. Thanks for sharing the knowledge. Stay blessed!!!

Thank you Ilyas for your support and wishes !!

[@Andreas-qs7xn]

That was very clear and concise without oversimplifying. Thank you!

[@ITkFunde]

Thanks Andreas !!

[@BradenJohnYoung]

This is the most intuitive explanation of a proxy I've ever heard. Excellent!

[@ITkFunde]

Thanks Braden ☺️☺️🙏

[@lisaknieriem5852]

You’re examples are so easy to understand!
Thank you 🙏!!! You’re doing a wonderful job teaching. It’s harder, as we get older, to understand concepts that are new. You’re very much appreciated ❤️😉

[@ThorstenStaerk]

I love the "parent" explanation. Indeed, our traffic terminated there ;)

[@ITkFunde]

Thanks Thorsten 🙏☺️

[@sharanyak7816]

Detailed explanation. Really understood proxies pretty well. Thank you...

[@ART-gn3ps]

I love the way that is so simple but it comes with very great explanation and understandable. This is how the teacher should be.

[@julie.8]

Concise video with excellent visuals and examples!
Architecture review:
1. INTRANET [ Client requests Proxy (security of clients, better management of reqs, caching, encrypt/decrypt) ] INTERNET servers
2. INTERNET client requests INTRANET [ Reverse Proxy (security of servers, caching, compression, load balancing) Server(s) ]

[@ITkFunde]

Thank you Julie for summarizing :)

I like how you simplify the technical stuff. It helps a lot. I always get confused when it comes to networking and you just make it so easy to understand. Thank you.

[@sydneystriker5355]

Clear and Crisp. Thanks. Thumbs Up.

[@hrishabhg]

Simple yet Marvelous explanation. :)
I also love the video being noise-free.

[@ITkFunde]

Thanks Hrishabh

[@makz1099]

Excellent yet again - you know the art of teaching effectively by managing time

[@ITkFunde]

Thanks a lot for your continuous support 🙏

[@yuvabhagvatkathakarshriyag9305]

that one example of child-parent was enough to explain the whole concept! keep making such good videos, we will keep motivating you..

[@sjeyram]

Explained it with simple examples. Thanks for the video

[@ITkFunde]

Thanks Jeyram !

[@yourFifa13]

i understood proxy and reverse proxies but you finally made it click for me. proxies are essentially client side (benefit the clients) and reverse proxies benefit the business (server side)

[@ITkFunde]

Thanks Ibrahim for this feedback :)

[@askiebaby]

Thanks for your sharing, this video is so helpful that helps me understand the difference between proxy and reverse proxy quickly in simple examples!

[@ITkFunde]

Thanks Askie for this lovely feedback. I have made other tutrials using such simple examples do checkout ! ANSHUL

[@SahdevSur]

Parent-child relation example is easiest one to understand it.
Thank you for making great content. Keep it up.

[@FernandoOliveira1979]

Thanks for the knowledge sharing!

GREAT ANALOGY. Thank good work getting straight to the point. Thanks! 😀

[@benjaminayangbola1773]

If there was a love button, I'd use that instead. You just distilled the concept of proxy and reverse proxy in simple language. When I saw the parent-children analogy, I knew this was the video I needed. Thumbs up, man!

[@ITkFunde]

Thanks Benjamin I do have a love button while replying to your lovely comment and that is superrr clicked 🙏☺️

[@theone3939]

Thank you for sharing. I'm new to network administration. I am by trade a Mechanical Technician. But, the cost living is going up. So, now I need a hirer paying job. I have many years experience in the electronic production industry, and I never consider network admin for a career. I have clearly made the right choice to stick with my new found career choice. I am so excited to start this new path. Yup, I am 47 yrs old man and want to change my career choice. I am now a subscriber. Have a great day.

[@ITkFunde]

Thanks and all the very best, Inam sure you will do great in this new found career and passion. 🙏

[@enggarantin7580]

A proxy server acts as a gateway between you and the internet. It's an intermediary server separating end users from the websites they browse. ... Proxy servers act as a firewall and web filter, provide shared network connections, and cache data to speed up common requests.

[@bethuprashanth9820]

Well explained 👏👏..
Small question...
I have load balancer for my k8s cluster... Can this LB secure my application as proxy server does? Like firewall, encryption, caching, securing???

[@ITkFunde]

Thanks Benthu load balancer and reverse proxy server are quite similar in a way that both become the public face of your backend application. LB is diff in a way that in case of huge demand LB can help balance incoming requests. However even if youbhave single app server then too reverse proxy can be setup to hide its identity from public. Products like NGINX provide both LB and Reverse Proxy capabilities into one. Hope it helps. Thanks Anshul Tiwari
