nginx is a web server software designed to serve HTTP content for websites and applications, commonly used by developers and system administrators for its reliability and performance. It acts as a reverse proxy, load balancer, and HTTP cache, making it suitable for high-traffic environments and scalable deployments.

• Reverse Proxy: Directs client requests to backend servers, improving security and load distribution.
• Load Balancing: Distributes incoming traffic across multiple servers to enhance availability and prevent overload.
• HTTP Caching: Stores frequently accessed content to reduce server load and speed up response times for users.
• Low Resource Usage: Operates efficiently with minimal memory and CPU consumption, ideal for resource-constrained systems.
• Modular Architecture: Supports extensions through modules for added functionality like SSL/TLS encryption and compression.
