10. HNSciCloud Joint Pre‐Commercial Procurement
Procurers: CERN, CNRS, DESY, EMBL‐EBI, ESRF,
IFAE, INFN, KIT, STFC, SURFSara
Experts: Trust‐IT & EGI.eu
The group of procurers have committed
• Procurement funds
• Manpower for testing/evaluation
• Use‐cases with applications & data
• In‐house IT resources
Resulting services will be made available to end‐
users from many research communities
Co‐funded via H2020 Grant Agreement 687614
Total procurement budget >5M€

Combining services at the IaaS level to support science workflows
The R&D services to be developed are to be integrated with
Resources in data centres operated by the buyers group
GEANT network

12. Challenges
Innovative IaaS level cloud services integrated with procurers in‐
house resources and public e‐infrastructure to support a range of
scientific workloads
Compute and Storage
support a range of virtual machine and container configurations including HPC
working with datasets in the petabyte range
Network Connectivity and Federated Identity Management
provide high‐end network capacity via GEANT for the whole platform with
common identity and access management
Service Payment Models
explore a range of purchasing options to determine those most appropriate for
the scientific application workloads to be deployed

15. Top 10 challenges for RIs and EOSC to work together
1. Scalability of services - catering for the needs of small research groups from public and
private sectors, as well as very large experiments
2. Integration - services linked by a supported federated identity scheme covering more of the
research life cycle where users access data, sw, IT capacity and the expertise for performing
analyses
3. Hybrid model - should not compete with but rather profit from ease of use and rates of
innovation of commercial service providers
4. Provenance, citation and use of data & software that respects intellectual property rights
5. Software licence models that allow flow of data across different infrastructures without
buying licences for each one
6. Confidentiality of data that is still under embargo for publication or intellectual property
reasons
7. Cyber security vulnerabilities must not compromise participating organisations
8. GDPR compatibility for all services
9. Adoption - Making end users aware of the services and encouraging them to use them
10.A Governance model that ensures end‐users and procurers drive the decision making
process
Result must be sustained via funding
models that take a long-term view
