Navitia is made of 3 main modules:

1. Kraken is the c++ core (Heavy computation)
2. Jörmungandr is the python frontend (Webservice and lighter computation)
3. Ed is the postgres database (Used for preliminary binarization)

Kraken and Jörmungandr communicate with each other through protocol buffer messages send by ZMQ.
