nginx is a web server, reverse proxy, and load balancer used by system administrators and developers to serve web content and manage network traffic. It is built for environments requiring high concurrency, performance, and reliability.

• Reverse Proxy Server: Acts as an intermediary for client requests, forwarding them to backend servers and returning the responses. This improves security and distributes load.
• Load Balancing: Distributes incoming network traffic across multiple servers to ensure no single server becomes overwhelmed, enhancing availability and responsiveness.
• HTTP Caching: Stores copies of frequently accessed content to reduce server load and decrease response times for users.
• Low Resource Usage: Operates efficiently with minimal memory and CPU consumption, making it suitable for systems with limited resources or high-demand scenarios.
• Modular Architecture: Supports extensions through modules, allowing administrators to add functionality like security features or additional protocols as needed.
