Goodbye Litespeed, hello Nginx, says WordPress.com
As mentioned earlier, WordPress.com has made the move from Litespeed for their frontend serving needs to Nginx, the little lightning fast server from Russia. Matt had mentioned that they were quite happy with LiteSpeed, but wanted to move to something else purely to have their entire stack run with open sourced software.
It is a huge boost for Nginx, which has in any case been growing at a rapid pace in terms of adoption in the recent years, especially as a reverse proxying solutin for the Ruby On Rails crowd. What is quite interesting is that WordPress.com is running the development version of the software (0.6.29) than the stable one (0.5.35). There is, though, no clarity if Nginx is being used purely as a reverse proxying solution for WordPress.com, or if it is actually serving PHP too though the FCGI route.
According to Netcraft, the switchover was made on 11th of April.
