nginx is a web server software designed for system administrators and developers who need to host websites and applications. It focuses on delivering content quickly while using minimal server resources.

• Reverse proxy and load balancing: Distributes incoming traffic across multiple servers to improve performance and reliability.
• HTTP caching: Stores frequently accessed content to reduce server load and speed up response times for users.
• Handles static content efficiently: Serves files like images, CSS, and HTML directly with very low overhead.
• Event-driven architecture: Manages many simultaneous connections without creating a separate process for each one, leading to efficient memory use.
• Configuration flexibility: Uses a straightforward text file for setup, allowing precise control over server behavior and security rules.
