Grafana enterprise help

I had a few doubts about the Grafana enterprise subscription.

  1. Once we subscribe to it by giving the full payment will it be permanent or is it a monthly cost?
  2. Like there is a payment model of Grafana pro based on per user, is the enterprise similar or do we get unlimited users with it?

may give you an indication of whether you want to call the sales team for a
specific quotation.
