Galaxy prototypes have been written in Node.js, but the language choice should still be discussed.
The backend architecture (galaxy-api) is written in Node.js.
 
Below is a list of pros/cons of Node.js and Python (a possible candidate for the Game Center).

=== Pros ===
* Mozilla has deployed Python projects to scale (e.g., AMO, Marketplace)
* SQL ORMs are mature (SQLAlchemy, Django ORM)
* Frameworks are fantastic (Flask, Django [TE - we actually have a specialty framework for services: http://cornice.readthedocs.org/en/latest/])
* Synchronous code (easy to write)
* Mature libraries (and well-documents too)
* Strong community
* Simple syntax (makes it easier to write things elegantly)
* [TE] At the moment, we probably have more resources available on the Python side
=== Cons ===
* Synchronous, blocking code
* Real-time, socket network is unnatural and difficult (forced to use such libraries as Tornado/Twisted/gevent)
* Throughput (requests per second) can be lower than Node.js's (depending on which benchmark you read)
