WHAT IS REVERSE PROXYING AND WHY IS IT USED IN MODERN HOSTING?

Question

Accepted Answer

A reverse proxy is a server technology where a special intermediate server accepts incoming requests from internet users and redirects them to one or more internal hosting servers, hiding their real architecture and IP addresses. Unlike a regular proxy, which protects the client, a reverse proxy protects and optimizes the performance of web servers by acting as a single entry point for all external traffic.

Setting up a reverse proxy allows you to efficiently solve many architectural tasks in web development and system administration.

1. Caching static content such as images, styles, and scripts, which significantly reduces the load on the main backend server.
2. SSL termination, where the proxy server handles all traffic encryption, freeing up the CPU resources of the main application.
3. Load balancing of incoming requests across multiple instances of a website to ensure high availability and project scalability.
4. An additional layer of security that filters malicious traffic, hides the internal network structure, and protects against certain types of network attacks.

Popular software solutions for implementing a reverse proxy are Nginx, HAProxy, and Traefik, which are easily configured on any modern VPS. The use of these tools has become an industry standard for deploying even relatively small websites, providing them with a professional level of performance and security.
