what is the exact meaning of sandbox in splunk enterprise?

Hello every one
In Splunk Enterprise, for premium products, it has a free 7-days trial call it sandbox!
As I know, it is a cloud server; but I couldn't understand why they call it sandbox, in my opinion sandbox meaning is a little bit different.

I will appreciate in advanced for your response

A sandbox in this instance is a small, temporary "play" area in which to experiment with and learn about Splunk.
