Nginx is an open-source web server that offers high concurrency with low memory use. It is also used a load balancer, HTTP cache, and reverse proxy server. Instead of creating new processes for each web request, Nginx uses an event-driven approach asynchronously where requests are handled in a single thread.

Nginx is known for its performance optimization under scale, which is why it is used by top companies as a server host. It outperforms other servers in many benchmark tests with static content or high concurrent requests. 

Nginx has been tested by Apps4Rent engineers and it works well on CentOS 8.5:
