Understanding the Dynos
A dyno is a single virtualization in a Unix container. This container contains the slug of
your application created during the deploy and you can add more dynos at anytime for scal-

ClearDB MySQL Database, MongoLab (MongoDB), Redis Cloud, GrapheneDB, or others
to share a database data between your dynos. You can see all the available data stores' add-
