JSC offers a Cloud computing platform for users with a demand for more complex use cases, such as services based on data residing in the HPC file systems. The resources have been procured as part of the Helmholtz Data Federation (HDF) activities, thus the name HDF Cloud.
The HDF Cloud at JSC comprises OpenStack compute, network, and volume services as well as an integration with the DATA file system also available on the HPC systems. Additional OpenStack services are also available.
The current status of the cloud environment can be found on the general JSC status page.
Please subscribe to the HDF Cloud mailing list by sending an email to firstname.lastname@example.org. This is a low traffic list for important updates and announcements regarding the cloud resources.
HDF Cloud ressources are available for users of JSC's HPC systems and partners in cooperations with JSC. In order to gain access to the Cloud resources, please apply for it by sending an email to email@example.com, describing your use case, affiliation, and resource requirements. We will then let you know whether your use case qualifies and we are able to accomodate it.
As a staff member of a Helmholtz Centre, you can immediately login using Helmholtz Login ("Authenticate using Helmholtz AAI"). This does not automatically entitle you to any resources, but registers you in the service and we can immediately assign resources upon your request.
Should you need support with any of the offerings or have questions, please contact the data services support team at firstname.lastname@example.org.
We are available during normal business hours: Monday through Friday 8:00 am – 5:00 pm CET with the exception of German national and regional (NRW) holidays. We are also unavailable between Christmas and January 1st.
When publishing results that have been facilitated by using HDF Cloud, you must cite HDF Cloud like the following:

Furthermore, you must acknowledge the resources used:
The authors gratefully acknowledge the Helmholtz Data Federation (HDF) for funding this work by providing services and computing time on the HDF Cloud cluster at the Jülich Supercomputing Centre (JSC).
The following documents describe how to access the HDF Cloud and the first steps required to make use of it. For those users, who want to just access the cloud, the web interface of the Cloud is available at https://hdf-cloud.fz-juelich.de/. Relevant topics for using the cloud are:
