Using a dashboard, researchers can create and manage cloud-based IT resources such as virtual machines (VM), storage or network components as needed. While acquiring physical hardware often requires a great deal of time and resources, virtual IT infrastructure can be set up with just a few clicks and customized to fit the individual needs of a specific research project.

All heiCLOUD data is securely stored in the URZ server rooms and can be accessed through the X-WiN research and education network.  heiCLOUD use is charged either by time or resource consumption.
