From what i know. Frontend technologies is mostly java (for server side code) and angular 1 (for client side code).
Backend technologies contains java (according to the SDK) but maybe there is more (probably a sql database with that).

To run games and puzzles, everything is based on “server on demand” services like amazon and google services.

You get a few insights about the scalability in this blogpost.
