nginx is a free, open-source software for serving web content, acting as a reverse proxy, load balancer, and HTTP cache. It is designed for administrators and developers who need a reliable, high-performance foundation for websites and applications.

• High Performance Architecture: Uses an asynchronous, event-driven model to manage thousands of concurrent connections with minimal memory usage, making it efficient under heavy load.
• Reverse Proxy and Load Balancing: Distributes incoming traffic across multiple backend servers to improve reliability, scalability, and application performance.
• Static Content Delivery: Serves static files like HTML, CSS, and images directly with very low latency, often faster than traditional application servers.
• HTTP Caching: Can cache responses from backend servers, reducing load and speeding up content delivery to repeat visitors.
• SSL/TLS Termination: Handles the encryption and decryption of HTTPS traffic, offloading this computationally intensive task from application servers.
