Google Web Server (GWS) is proprietary web server software that Google uses for its web infrastructure. In May, 2015, GWS was ranked as the fourth most popular web server on the internet after Apache, nginx and Microsoft IIS, powering an estimated 7.95% of active websites. …

Nginx has grown in popularity since its release due to its light-weight resource utilization and its ability to scale easily on minimal hardware. Nginx excels at serving static content quickly and is designed to pass dynamic requests off to other software that is better suited for those purposes.

Because it can handle a high volume of connections, NGINX is commonly used as a reverse proxy and load balancer to manage incoming traffic and distribute it to slower upstream servers – anything from legacy database servers to microservices.

In fact, Nginx is used by some of the most resource-intensive sites in existence, including Netflix, NASA, and even WordPress.com. Apache’s usage, on the other hand, moves in the opposite direction as a site’s traffic increases. It powers: 24.0% of the 100,000 most popular sites (down from 27.1% in 2018)
