Nginx

Nginx is an open-source software that is used for web serving, reverse proxying, caching, load balancing, and many more. 

Using Nginx you can minimize your memory usage and achieve high concurrency. Instead of creating new processes for each web request, the technology uses an asynchronous, event-driven approach where requests are handled in a single thread. Nginx is able to pass dynamic requests off to other software that is better suited for those purposes.

Nginx makes websites work faster. This way they can rank higher in Google search. It’s the fastest and the best technology for serving static files and is compatible with many popular web applications.
