They host "scripts" and "apps" that you can execute against "resources" (i.e. databases etc...). So basically a lightweight, online environment for running code without any deployment? I suppose an example might be marketing has a DB of prospective customers and this would allow devs to quickly write scripts to clean it, apps to allow people to add to it and automated tasks to trigger events (eg. an email) based on certain metrics etc... I guess it means being able to rapidly build fairly throwaway systems for internal use.
