• Event-driven architecture: Processes multiple connections within a single thread, reducing memory and CPU overhead compared to traditional servers.
• Reverse proxy and load balancing: Distributes incoming traffic across multiple backend servers to improve reliability and scalability.
• HTTP caching: Stores frequently accessed content to speed up response times and reduce load on application servers.
• SSL/TLS termination: Manages encrypted connections efficiently, offloading decryption work from backend systems.
• Modular configuration: Allows customization through a flexible configuration file system to adapt to various hosting needs.
