Brilliant, thanks Nana! I don't work in Networks or IT but I'm a software engineer and we often end up assisting on outage calls where the problems typically lie outside my area of expertise. Videos like this (that are so clearly explained) are invaluable in helping me understand the general architecture of our services. (Well, some of them, anyway. Haha. It really varies between our mix of brand new and decades-old applications 😂)

It is very important give content without confusing topics with same context. Explaining about other load balancers in cloud providers is very important to deliver content very clearly with best practices in practically. Thank you
Thanks for explaining this in such a clear and engaging way, especially by setting up the story! The restaurant example is brilliant-I'll never forget the difference between proxy, reverse proxy, and load balancer now. Appreciate all the effort that went into making this video
I wish you had this video out a few weeks earlier, it would have saved me many hours of reading, getting an understanding most of what was in this video. You had a few things that I didn't know about, mostly because I wasn't looking for them. But, now I know are few more things than I did 20 minutes ago.
Thank you always for your simplified explanations. I would like to see a tutorial on: 1. Bash scripting for cloud/devops Engineers 2. Linux for cloud/devops engineers 3. Linux networking for cloud/devops engineers Thank you :)
I would like to add that cloud load balancers like AWS ALB has a feature ‘session stickyness’ which helps in session persistence, speaking of filtering through request headers and url paths would need more aws services to come into play. So I can conclude that your implementation constraints (time and budget) will define wether is good idea or not to duplicate load balancing operations.
Thank you for this good summary and explanation. Regarding using two reverse proxies for additional featgures and security I think that current cloud-load balancers (like AWS Application LB) already offer a lot of the features like NGINX, e.g. SSL termination, URL Paths and request headers which in many cases make an internal LB obsolete.

Great video I can show people I work with, as someone in security though I cringe a bit when I hear things like "will scan for any threat/malware/virus" esp on something like a proxy which is likely doing quite targeted scanning, let alone that most proxies aren't even configured to scan malware by default (as far as I have seen - it was said as if it was 100% something it does).
Thanks for the video I really appreciate the effort in your videos and I had to watch the video 2 times to get a clear picture and the visual shield more light to it. Just a question. Can we say forward proxy = proxy meaning it sits on the client side while the reverse proxy sits on the server side?
Thanks Nana🎉, your videos helping me to reach next step to my Devops journey. I have one request can you please make one video on how to setup an SSL certificate for any website and Which one is the best aproch to create certificate and setup SSL.
On the subject of cloud load balancers + reverse proxy, specifically on AWS, you could have a private Application Load Balancer (in a private subnet) and create a hosted zone on Route 53 with (alias) pointing to the private load balancer. Thereby, eliminating the need for 2 load balancers (public and private).
Im not super familiar with AWS, but if Route 53 is just DNS and the Application Load Balancer is private, how does the traffic get to it? Unless Route 53 also acts like a proxy in which case its back to 2 proxies?
@@benhook1013 Route 53 has both private and public hosted zones. Route 53 acts as a DNS but with extra features like aliases, traffic flow, etc. Yes, in this case Route 53 acts as a proxy. However, it's cheaper than having 2 load balancers. And also Route 53 is a global service and you don't have to worry about HA, etc.
Thank you Nana, is it possible for you to make a video in which we can create an application, go through creating kubernetes ingresses and pods and making configurations and security by using forward proxy and reverse proxy with AWS load balancer?
I really enjoyed this video, as well as the "Full NGINX Tutorial - Demo Project with Node.js, Docker"! However, I have the same question about both: you mention that we need both the cloud provider's load balancer (e.g., AWS) and a reverse proxy load balancer (e.g., NGINX). While I understand the role of the reverse proxy from your examples, I’m unclear about the specific benefits of the cloud provider’s load balancer. What purpose does it serve if it always routes to the same reverse proxy, or is it meant to handle multiple reverse proxies? Could you please elaborate on why the cloud provider's load balancer is needed and perhaps provide a practical example? Thanks!!
Thanks for the great video, Nana. One question: in many books there is a "third" type of proxy called "transparent". From what I understand it seems that clients are "aware" of forward and reverse proxies (forwards, especially, as they require some sort of configuration on the client itself - something I have only done once, back in the day, from the "Internet option" in Internet Explorer), whether a transparent one is completely... well, transparent to the client. Can you please add your two cents on this? Thank you, and keep up with your great work!
I have understood that the nginx ingress controller uses ingress resource to create the needed aws load balancer. So the controller itself does not handle traffic.
Awesome content, thank you so much for all of this work!!! I have a question though, on the chapter "Are Cloud Load Balancer a replacement or addition? And Why?"... You explain that, in practice, one may use a load balancer (i.e. nginx) to balance loads within a private subnet, while an AWS load balancer handles public requests... But from the diagram, I do not understand how this AWS entry server works as a load balancer since it only connects to one machine. Does it mean a real situation involves several nginx reverse proxies?
This is awesome 👍. Could you please create a video about Gunicorn and its Threads. How does reverse proxy work with it? And also how can we add Nginx with Gunicorn. Thank you 🙏
The explanation in the video is a bit confusig, in the beginning, she described a firewall, not a proxy. A Forward Proxy is essentially hiding the IP of the client by doing the requst with its ip on behalf of the client. A reverse proxy on the other hand, is set up on server side and redirect the request to the correct internal service thus allows rhe server administrator to not expose any service on any port to the public as the reverse proxy will route a request based on used domain to an specified service. The reverse proxy itself has access to internal services with their ports, even if the service is not exposed to the public.
Seeing that the cloud load balancer has just a single reverse proxy server to talk. Is it necessary to have them there or is it just a representation error. Does the use of cloud balancer entail having to scale the reverse proxies (ingress controller)?

Excellent explanation Nana. I always learn a lot with your videos. They have no equal.
Hi @TechworldNana, I want to do this course,
Thanks!
Thanks for the support! :)
this 13 min video on reverse proxy / nginx make me understood things that i wasnt able to in the last 6 months
Thanks

The best video about Proxy and Load Balancers
Great video, simply explained!
Nana your content is so great! Thank you and keep going! With your videos I literally went from zero to hero !
Excellent as always! Thank you!
Outstanding teacher as usual. thanks Nana
You are naturally talanted. Thanks for this clear explanation
A really good video for those new to IT Administration. Or for people who just want to understand the Infrastructer of the Internet.
This was unimaginably useful, thanks a bunch!
Thanks for the awesome explanation!
Nana, you are just a talented teacher. Well explained and understandable. Thank you so much!
Excellent explanation! Very good quality content both for beginners and not)
Big fan nana, following you for years ❤🖤

Very helpful as usual 😁 Thanks very much Nana
your videos are very informative and no non-sense talking, to the point and clear with solid examples, keep it up, Thanks and Bless you
Great explanations
Thank you Nana :) The metaphors always help
thank u
very good explanation
i think the load balancing thing really helps me to remember what a reverse proxy is
Good experience thank you so much Nana 😊
This was amazing! I'm glad to have watched this!
Very well explained, Thank you! 👍🏻
Thank you always for your simplified explanations.
I would like to see a tutorial on:
1. Bash scripting for cloud/devops Engineers
2. Linux for cloud/devops engineers
3. Linux networking for cloud/devops engineers
Thank you :)
Many thanks and great suggestions I will definitely consider! 😊
The third one is a must! It would be very much appreciated
As usual ! Great content with such an amazing presentatation 😀 thanks
As excellent as ever
Too good and made simple explanation Nana. Thanks for the new tech videos.
I would like to add that cloud load balancers like AWS ALB has a feature ‘session stickyness’ which helps in session persistence, speaking of filtering through request headers and url paths would need more aws services to come into play. So I can conclude that your implementation constraints (time and budget) will define wether is good idea or not to duplicate load balancing operations.
Once again a fabulous video.
Thank you for the invaluable contribution to IT. I am waiting for end to end course on MLOPS or AIOPS from you.
Thank you for this good summary and explanation. Regarding using two reverse proxies for additional featgures and security I think that current cloud-load balancers (like AWS Application LB) already offer a lot of the features like NGINX, e.g. SSL termination, URL Paths and request headers which in many cases make an internal LB obsolete.
As always an amazing job Nana
Thanks for your great feedback, happy to hear!
Wow! Fantastic video! Thank you!
Glad you like it! :)
Hello, I love the way you teach Thank you!! Q. I couldn't find the Java lesson
I wish I had found you earlier. Grateful.
Thanks a lot.
I love how you explain your videos
Thanks for the session!
Thank you for such good explanation!
Thank you for the more informative video.

Thank you, Nana! Great video, I learned a lot. Could you please make one on API Gateway?
Thanks for the video I really appreciate the effort in your videos and I had to watch the video 2 times to get a clear picture and the visual shield more light to it.
Just a question. Can we say forward proxy = proxy meaning it sits on the client side while the reverse proxy sits on the server side?
Thank you ❤
Cool, thanks!
My pleasure :)
Brilliant
hi im new here thank for amazing presentation you got my sub ❤
As a old fashioned system manager, we are using apache as forward-reverse proxy server. Nginx is being populer rather than apache as ı can see.
good job 😍
Thank you Nana for this useful video! 😍
Thanks Nana🎉, your videos helping me to reach next step to my Devops journey. I have one request can you please make one video on how to setup an SSL certificate for any website and Which one is the best aproch to create certificate and setup SSL.
The sound is perfect
Thank you for confirming 🙏
Please make a video on rabbitMQ message queue service
Thanks for the suggestion!
quuite insightful
it's correct to say that in the k8's case the aws load balancer is the entrpoint node of the cluster of kubernetes? probably i am confused
Thank you
You're welcome :)
😁😁 thank you
Hello 👋 Nana - thank you for this video. Question: Does the Reverse Proxy use Consistent Hashing or the Cloud Load Balancer or both?
Super helpful ...hey nana can u make a video on rpc.Thanks
Thank you for the information can you make a video about azure front door and functionalities
This is what is called peeling banana skin and feeding 😂 I can’t explain it in any better way 😊
Hi Nana. Your videos explain very good. Do you have videos that teach the details of Nginx configuration and HTTPS configuration?
Thanks for helping with my inposter syndrome
Was literally just thinking about this topic lol
What a coincidence :D
Same 💯, was about to comment
thank you : )
