Nginx is a powerful high-performance web and reverse proxy service that also provides IMAP/POP3/SMTP services. In the case of high concurrent connections, Nginx can support responses up to 50,000 concurrent connections.
Nginx as a load balancing service: Nginx can directly support Rails and PHP programs to provide external services internally, and can also support external services as an HTTP proxy service.
Handle static files, index files, and auto-index; open file descriptor buffering.
Cache-free reverse proxy acceleration, simple load balancing and fault tolerance.
FastCGI, simple load balancing and fault tolerance.
