BioExcel-2 Deliverable 2.5 - Provision of a Workflow Environment at BioExcel portal

The deliverable presents the work to provide execution environments for workflows developed within the BioExcel 2 period. The first section introduces the concept of workflow environments in the BioExcel Project, providing the context of the work done in the previous BioExcel 1 grant period and presents the current ecosystem around the BioExcel Cloud Portal. The second section presents the Cloud Portal in more detail together with VM-based environments for workflows that are available in the portal. Different flavours of virtual machines (VMs) are presented, including BioExcel 1 pre-built VMs and dynamically built machines for Common Workflow language (CWL) and Jupyter Notebook execution. Finally, the third section presents the newest type of workflow infrastructure in the form of the Binder installation and its container-based notebook servers. This deliverable concentrates on execution environments for workflows and as such, does not describe the workflows themselves. All demonstration workflows added to the Portal during BioExcel 2 have been previously and extensively described in Deliverable 2.3
