nginx is a web server and reverse proxy server known for its high performance, stability, and low resource usage. It is used by system administrators and developers to serve websites, manage load balancing, and act as a security gateway for applications.

• Event-Driven Architecture: Processes requests asynchronously, allowing it to handle thousands of concurrent connections with minimal memory use.
• Reverse Proxy & Load Balancer: Distributes incoming network traffic across multiple backend servers to improve reliability and application performance.
• HTTP Caching: Stores static and dynamic content to reduce load on origin servers and speed up response times for users.
• High Performance: Efficiently serves static content and can manage fast CGI, uWSGI, and SCGI protocols for dynamic content.
• Modular Configuration: Offers flexibility through a straightforward configuration file structure for setting up virtual hosts, SSL/TLS, and access rules.
