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

So nice of you

[@irfanshaik1302]

what a nice way to compliment someone 👏

[@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

[@EYNugget]

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.

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

[@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 !!

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) ]

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

[@ITkFunde]

Thanks Hrishabh

[@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 :)

[@fasid93]

Really liked the feature points that you laid out for each concept like, caching, encrytpion, gzipping. Good one :)

[@kalpazan52]

This is by far the best explanation of proxy vs reverse proxy. Thanks so much!

[@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!

[@SlowShadows988]

Great examples with the mom and dad. I like how you explain things as you go such as caching. Thank you for doing this! :)

[@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.

[@raghavendrapothula7773]

Brilliant: very simple understanble.

[@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

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.
