nginx is a web server and reverse proxy server known for its high performance, stability, and low resource usage. It is widely used by system administrators and developers to serve websites, act as a load balancer, and proxy requests to other servers.

• Event-Driven Architecture: Processes multiple connections within a single thread, leading to efficient memory use and the ability to handle thousands of concurrent connections.
• Reverse Proxy & Load Balancing: Distributes incoming network traffic across multiple backend servers to improve reliability and application performance.
• HTTP Caching: Stores static and dynamic content to reduce response times and decrease the load on upstream servers.
• SSL/TLS Termination: Manages the encryption and decryption of HTTPS traffic, offloading this computationally intensive task from application servers.
• Configuration Simplicity: Uses a straightforward, human-readable configuration file structure for setting up virtual hosts, security rules, and performance optimizations.
