 The hardware environment used by the eWaterCycle platform development team is the [SURF Research Cloud](https://servicedesk.surfsara.nl/wiki/display/WIKI/Research+Cloud+Documentation). Starting a machine on the Surf Research Cloud requires that you have research budget with SURF, for more info see the website of [SURF](https://www.surf.nl/en/research-it/apply-for-access-to-compute-services). Once running, access to the machine can be shared to anyone.
