Sad news, comrades.
In all holywars about Perl vs Everything some high-loaded Perl projects was already mentioned. One of them was YouPorn - one of largest
porn ahem .. adult entertainment websites in the world.
But not anymore.
You can check presentation (
PDF /
PPTX /
GoogleDocs) of their technical lead on Confoo conference -
Written in PERL with a very complex architecture
First few months dedicated to learning the site, maintain it, and plan the re-write.
Re-write started in August 2011 and was originally planned for a delivery in mid-November.
Actually launched at the end of January.
So, in the end of 2011 site was completely rewritten on PHP - it's simplier, faster and easier to find staff.
Another architecture is pretty neat and straightforward - HaProxy + Varnish + Nginx/PHP-FPM/Symfony2 + Redis/MySQL + Syslog-ng for logging, only one strange decision - they are using ActiveMQ for DB/Redis writes managing, but as far as I understand from presentation it's not very good solution for them...
