Separate code from configuration.

Armada automatically delivers right configuration for your service environment taking it from configurable source such as git. If you run the service with:

$ armada run game --env production

and have the config repo:

Configuration repository

then you can use the following code to access config files:

games_db_config = hermes.get_config('games_db.json') mysql_connect(games_db_config['host'], games_db_config['user'], games_db_config['password'])

The code is the same for dev and production.

Connect to dependent services (and load balance between them) in the simplest way possible.

There's a HAProxy instance running in each container responsible for discovering and load balancing services.
