There is not an open source version as yet, but you can spin up these instances on an hourly basis on AWS https://aws.amazon.com/marketplace/pp/B01M0ZY2OV?qid=1475606... and on IBM Softlayer.
I have to say it seems your pricing for such a new entrant and before having built share, is bound to attract very stiff newcomer competition. "Interesting" business model.
You can install this on AWS or on your own infrastructure (I run this on my laptop for example).
