Nginx

Nginx isn’t just the fastest web server around; its scalable underlying architecture means it can perform many functions outside of web content serving. Nginx is frequently used as a reverse proxy and a load balancer, processing a high volume of incoming traffic and distributing it to slower upstream servers, because it can handle a high frequency of connections.

Nginx is made up of a master process and multiple worker processes. The primary functions of the master process are to read, asses, and maintain worker processes, while the requests are processed by workers. To effectively distribute requests between worker processes, Nginx uses an event-based paradigm and OS-dependent methods. The configuration file specifies the number of worker processes, which can either be fixed for a specific configuration or automatically updated to the number of CPU cores available.
