nginx is creating a name and market for itself as a reverse proxy, even though there are better solutions for reverse-proxies out there, everything from HAProxy to Apache Traffic Server to even Apache httpd. But this is an important market to have. Why? Because it allows for the perception that the "web runs on nginx" simply because all you see are the nginx web proxies and nothing behind that.<p>So what are the servers behind nginx? 9 times out of 10 it is Apache httpd, and numerous instances of it at that. So for each single nginx server "seen" in these surveys, there are unknown <i>multiples</i> of Apache httpd behind the scenes doing the real work.<p>But all that messes up the popular, if incorrect, narrative that Apache httpd is dying and nginx is gobbling up instances. It's all about marketing baby, for a product that really isn't truly "open source" but more so open core. And people buy it hook, line, and sinker.
