I would rate the cost 3 out of 5. There are additional costs other than licensing fees.

Pricing for the customers is really easy, as it is pay per use. If any server is switched off, you don't have to pay for anything. Customers can control the minimum and maximum price for their environments very easily from the control panel. There are no surprises at all!

Pricing for providers is revenue-shared based. Providers should invest in hardware to set up the Jelastic cluster.
