I am new to cloud for testing.
I am particularly interested in finding a database management tool for test data that utilizes cloud.
We are dealing with terrabytes of data on a daily basis in our production environment.
Databases, mainframe, pre COBOL languages, etc.
We have not finalized our testing tools yet. The test environment will likely dictate the entire suite of tools, but not neccessarily.

Any tips of the trade and specific tool insights would be appreciated.
