nginx is a popular open-source web server and reverse proxy server software. It is designed for high concurrency and efficient handling of static content, making it a primary choice for developers and system administrators running modern websites and applications.

High Performance & Low Resource Usage: nginx uses an asynchronous, event-driven architecture to manage connections. This allows it to handle thousands of simultaneous connections with minimal memory consumption, improving site speed and server efficiency. Reverse Proxy & Load Balancing: It can act as a reverse proxy, distributing incoming traffic to multiple backend servers. This provides load balancing, increases fault tolerance, and helps manage application scaling. Static Content Delivery: nginx excels at serving static files like HTML, CSS, JavaScript, and images directly to users. This offloads work from application servers, significantly reducing response times. SSL/TLS Termination: The server can handle the decryption of HTTPS traffic, freeing up backend resources. This simplifies certificate management and secures connections between clients and your infrastructure. Simple Configuration: Configuration is managed through a human-readable text file using a straightforward directive-based syntax. This makes it easier to set up, customize, and maintain compared to more complex alternatives.
