Yeah I've been skeptical of nginx's Lua support in the past. I guess I discounted it because it was a relatively unknown feature and Lua is obviously not nearly as popular as JavaScript. I don't know of any production service written exclusively in Lua, though I'm sure there are some. So yes while this is just a continuation of a bad idea, it's a rather substantial continuation. I fear that a lot more people will make use of this than make use of nginx's Lua support.

I have read that cloudflare uses nginx lua a ton. Apparently so does taobao (via tengine?).

OpenResty is built on Nginx's Lua support and is fairly popular. You're probably using websites that use it without knowing it.

  There's also Lapis, a really great and reasonably feature-full web app framework for OpenResty: http://leafo.net/lapis/ http://leafo.net/lapis/. I wrote a website in it recently and was pleasantly surprised at how cool it is. It reminds me a lot of Rails, but everything works faster, especially on LuaJIT, and I actually like MoonScript (the compile-to-Lua language I'm using) for its expresiveness and aesthetics. Definitely recommend checking it out.

  We use the lua support in openresty to build our authentication layer for admin tools outside of those admin tools. Very easy to integrate it with a third party authentication platform and just provide auth for free to our app developers.

AFIAK, CloudFlare is entirely just Nginx+Lua scripts.

  That is not fully true. It became a lot more true during 2013, but CloudFlare had already been operating for a few years then. A lot of fairly simple code was retired to the profit of Lua code, which is way easier to maintain. There are still important modules written in C and compiled with Nginx. There are also proprietary extensions of the ngx_lua api to manipulate internal some internal aspects of Nginx within the scripts. source: I wrote a good chunk of both iterations.
