What is the role of proxy server ?

[@nandhinisakrapani3364]

Proxy server acts as an interface between user/client and internet and fetches all the information from the internet to the user basically like a firewall , it also does caching of the the same information that is asked by many users as a static file and keeps within it and fetches the information whenever asked for, and also as a load balancer

We can use web servers for load balancing in that case we can avoid ELB.

[@ServerGyan]

Yes, Kapil, We can use Apache / Nginx web server as a proxy which will work as a load balancer, but in that case, you will have to customize it as per your requirement.

Great Video, Do we also have a hands-on tutorial video available implementing the same architecture in channel.? I am more interested in the proxy servers which is sitting in middle to redirect read/write request accordingly to the db's.

[@pvenugopal2809]

Very appreciable efforts sir TQ so much for that. But i have one doubt how the web server can talk to App server and DB as well?

[@sudhansharikatla8862]

Here webserver is acting as reverse proxy, We have to mention proxy pass directive in webserver config file to connect with app server like {proxypass / appserverIp or applb}. any request comes to the webserver it will goes to backend I.e apply or app server

[@muralis4508]

Nice one .. do you have a video that covers how to check the load on servers ? I mean any tool or method ? And also how to check open and closed connections to backend

[@tusharpatil1757]

Nice Explanation Sir ... I have a question regarding real time project. We have a private ip for our ec2 instance on which our web application is hosted and we are using terraform to build our infra however when we perform a rebuild then the ip gets changed. Can you please advise what recommended approach should I follow to retain the private ip and the approach should be compliance.

Very misleading title. If you want to discuss troubleshooting then discuss troubleshooting not the design.

[@ServerGyan]

Changed Title, Thanks for your feedback
