Proxies and Reverse Proxies Your guide to internet intermediaries day 23 of system design basics
Have you ever wondered what happens behind the scenes when you visit a web page In many cases your request does not go directly to the destination server but instead passes through an intermediary called a proxy or reverse proxy These intermediaries help route traffic improve security and optimize the performance of web services
What is a proxy A proxy acts between your device and the network When you want to load a website you send the request to the proxy and it forwards it to the final server The server responds to the proxy and the proxy delivers the content to you It is like asking a friend to pick up a package for you
Why use a proxy A key reason is privacy A proxy can hide your IP address preventing the website from seeing your real location and adding a layer of anonymity Another common use is access control in corporate or educational networks where requests are filtered and logged
What is a reverse proxy A reverse proxy sits in front of one or more backend servers and manages incoming requests It decides which internal server to send each request to based on load balancing rules or server health It is like a receptionist directing visitors to the right department
Main functions of a reverse proxy Security A reverse proxy hides the real IPs of backend servers and helps mitigate attacks such as DDoS Load balancing It distributes traffic among several servers to avoid overloads and improve availability Cache and performance It can store static content to speed up response times and reduce load on origin servers Controlled access It allows applying authentication and authorization policies before passing the request to the backend
Practical benefits Privacy and anonymity Good security practices Faster performance thanks to cache and load balancing Granular control of access and policies
Real examples A VPN works like a proxy by routing your traffic through remote servers large providers like Netflix use reverse proxies and load balancers to distribute millions of requests NGINX and similar solutions are common tools for implementing reverse proxies and load balancers in modern architectures
Typical use cases Companies that need to scale web services implement reverse proxies for high availability Sites with geographic restrictions use proxies to route content and corporate networks use proxies to filter and monitor traffic
