The purpose of [Denodo Test Drives](https://www.denodo.com/en/denodo-platform/test-drives) is to provide a private, cloud-based sandbox environment for users to learn the powers of data virtualization and see how Denodo Platform can benefit them.
I registered for the test drives to get a glimpse of use cases that data analysts and data scientists may have. The test drive instances come preconfigured with all the necessary components so that I can limit my work to the test drive environments. Connecting to them from a local machine requires some configuration which needs administrator privileges. The test drive instances only grant us normal user privileges, so this is why it is not possible to connect to the instances from a local machine.
Hope this helps!
