Description
The VISA platform has been proposed as a common and local portal for data analysis services for the photon and neutron community. It seeks to abstract away site and experiment specific configuration with ready-to-use virtual data analysis environments and it keeps track of interactive sessions.
At the European XFEL, we have gained first experience with using the VISA platform for schools and trainings with internal and external audience. We adopted a Gitlab pipeline to prepare dedicated virtual machine images for each event and use-case, and provided all participants with access to VISA, enabling self-service provisioning of personalized learning environments.
Use-cases leveraged both interfaces that VISA combines, the remote desktop for graphical user interfaces, and Jupyter Lab for notebooks. We provide an environment accompanying a publication on EXtra-Xwiz, a processing pipeline for Serial Crystallography, and we conducted trainings on the Karabo GUI, the main operator interface of the control software at the European XFEL. These, amongst other use-cases, were useful incentives to iterate on our deployment strategy and to test VISA's multi-cloud capabilities.
In this talk, we summarize on lessons learned, and we provide an outlook on future activities.
