  1. User‘s Needs in theCloud Tomi Dolenc Jernej Porenta Arnes info@arnes.si TF-MSP, Heraklion 19-20. 9.2011

  2. Outline • Before: virtualserverhosting • After: „clouds“ • How & why • User‘s needs • Is our judgement clouded? • Relation towards commercial clouds

  3. Virtualserverhosting @ Arnes • “Guest virtual servers” - GVS • Typical VPS • Linux/Apache/MySQL stack • 1 CPU / 512Mb / 30GB • Packages: full (root access), partial (user access), closed (web based access) • (Virtuozzo, ~100 VPS/server) • Coverstypicalneedsofuserorganizations: • Website (CMS) • LMS (mostlyforschools) • Any other web based apps • Support: • Helpdesk 10/5 • Full VPS backup

  4. Extendedneeds • More disk space • More memory • Different platform (MS Windows) • Example: • Specific software • Digital archives

  5. Arnes clouds 2011 • Goal: enable tailored hosting for VIU + beyond • Project started late 2010 • Planned features • VM Hosting • Storage

  6. Arnes clouds 2011: VM hosting • Solutions tested • OpenNebula • Eucalyptus • Ganeti • Planned: • 10 physical servers • small/medium/large VM • total user control

  7. Arnes clouds 2011: VM hosting • Implemented – pilot phase: • 3 physical servers (will extend to 10) • Ganeti • Web managed VMs • Production: late 2011

  8. Arnes clouds 2011: Storage • Started Q2 2011 • Planned: iSCSI access to >1TB space • Pilot phase: • Started in May • Tests were OK • Production: October 2011

  9. Future • Translate to “true cloud” • Implementation: OpenStack • Dynamic provisioning • Advanced user needs: • Temporary computing power • API interface

  10. Future • Extend resources • Additional physical servers • Additional storage • Additional features • Predefined templates • Extended support (?) • Use private cloud for our needs

  11. Is ourjudgementclouded? • Going “cloud” looks appealing • First step not difficult • Marketing the buzz • Keeping with the IT development trends • Who needs it? • ROI? • Legal aspect?

  12. Assesment of user‘s needs • Only through selected interviews/personal contact • Users interested in anything that’s free • Very important: know & trust your provider • Feedback from the pilot: • Happy with the support • Want more (sky’s the limit)

  13. Resource allocation • No charges  Policy very important! • Internal user segmentation • Save enough for VIU needs • Maintain the helpful face • Will they use flexible CPU/storage (“true cloud”)?

  14. Planning the resources • Make sure the € is well spent • Flexible resource allocation • Add more as you go and let users ask for your € • Plan B: share/relocate to grid/HPC • (can consume pretty much everything)

  15. Legal aspect • Hosting personal data  Signing MxN contracts? • Our Information Officer is currently looking into European practices, we are trying to find how it works in reality • What’s your model?

  16. MITM to public clouds • Universities outsource email to the cloud (only students) • Google & MS not very interested in us • Universities slow in adopting AAI • VDI for schools? • Tempting but expensive • Companies reluctant to partner with NREN
