Nginx Basics

A large fraction of web servers use NGINX, often as a load balancer. Nginx's modular event-driven architecture Can provide more predictable performance under high loads. Nginx has a rich and popular feature set for managing SSL traffic, load balancing, restricting access, logging and monitoring, mail proxy, and others. Its HTTP proxy and Web server features include:

• Ability to handle more than 10,000 simultaneous connections with a low memory footprint (~2.5 MB per 10k inactive HTTP keep-alive connections)
• Handling of static files, index files and auto-indexing
• Reverse proxy with caching
• Load balancing with in-band health checks
• TLS/SSL with SNI and OCSP stapling support, via OpenSSL
• FastCGI, SCGI, uWSGI support with caching
• Name- and IP address-based virtual servers
• IPv6-compatible
• WebSockets and HTTP/1.1 Upgrade (101 Switching Protocols)
