Is Twitter still running on Rails? [closed]

Question

I know Twitter initially ran on the Ruby on Rails platform.

Is this true today?

Answer 1

Twitter has a very strange architecture. They started out on Rails but now it's a combination of Rails and Scala. They started replacing some of the backend functionality with Scala to get access to the JVM, but many of the pages are still served with Rails today.

Unfortunately Rails has gotten a bit of a reputation for not being scalable enough due to Twitter moving away from it. This is (in my opinion) a bad misconception - the problem Twitter was having was with long-running processes and with green threads (which don't use the OS threads). Also, how many applications have 300 million+ users?
