Aquarium¶

Aquarium provides charging and billing services for the Okeanos IaaS.

Getting Started¶

We use Scala for development and Git for version control.
You can find some helpful Scala resources here:

You can also find some statistics, generated every hour, here. The statistics are served by a VM in the Okeanos IaaS. So, we eat our own dog food.
