I'm considering splitting the demo into two, separate Tracker and Index configurations:

• To make them independently deployable.
• To make it easier for users who are only interested in the tracker.

Proposal 1

Keep this repo and create two folders, one per service (tracker, index)

Proposal 2

Create two new repos:

• torrust-tracker-demo
• torrust-index-demo

Even if they continue sharing the same domain.

I prefer proposal two, even if there is a small amount of configuration duplication.

If we deploy them using two different virtual machines, we can also evaluate the performance separately. Since we are planning to migrate to a new hosting, maybe it's a good time to do it.
