nginx is a free, open-source HTTP server and reverse proxy software used for serving web content and managing network traffic. It is designed for administrators and developers who need a reliable, high-performance foundation for websites, applications, and APIs. Its event-driven architecture makes it particularly effective in environments with many simultaneous connections.

• High-performance HTTP server: Efficiently serves static content and can act as a load balancer and HTTP cache, reducing the load on application servers.
• Reverse proxy capabilities: Routes client requests to backend servers, providing an additional layer of abstraction, security, and load distribution.
• Low resource usage: An event-driven, asynchronous architecture allows it to handle thousands of connections concurrently with minimal memory and CPU overhead.
• Modular configuration: Offers flexibility through a straightforward configuration syntax, allowing fine-tuned control over request handling, security rules, and logging.
• Stability and reliability: Known for its uptime and ability to run for long periods without requiring restarts, making it a common choice for high-traffic sites.
