We have implemented Apache Web Server in many projects: Everything from configuring Apache ourselves, to the bread and butter of most of our projects: data science. While we have also implemented other open source web Servers (lighttpd, et al), Apache is a package we come back to time and again. Our favorite toolchain is to implement a small, custom Linux distribution running nothing but Apache WS.
We have virtualized/containerized Apache, ran Apache on bare-metal, and even found some uses on embedded platforms such as Raspberry PI, Commodity (i.e. cheap) x86 hardware, pfSense (which includes its own Apache version, which we update and upgrade out of the box), firewalls, routers, gateways, and other devices. Additionally, with IoT related projects, we even load a small version of Apache to run PhP scripts, or upload environmental data from remote locations.
