Why the "Box" in "BaasBox"?
Because it is a stand alone application.
You just need a Java VM, unzip the package and type "baasbox", and there you are... your backend is ready to go!
No application server, no database to setup and configure.
All is embedded in one application: DB, Application Server and other cool stuffs!
Just one configuration file to change listening port, application name and other few parameters.
