2. Cloud for R&E: the process Vision: flexible, production-quality cloud services for Greek R&E community Rationale: –Step beyond Grid in terms of flexibility and availability –Economies of scale for the R&E community; solving understaffing problems, poor service, low maintenance –Minimizes the investment in equipment and support contracts Policy background: existing MoU in place for Grid computing, expanding for HPC as well Methodology: –Technical workshops and requirements capture meetings –Gradual offering of services, starting with storage, moving to VM on demand, IaaS, and then PaaS&SaaS –Paving the way to public sector Funding: 2.2ME Data Centres; 4.5ME s/w and services

3. Commercial IaaS vs own IaaS? Commercial IaaS – Amazon EC2 not an end-user service – Need to develop custom UI, AAI layers – Vendor lock-in – Unsuitable for IT depts persistent, long-term servers, custom networking requirements Gain know-how, build on own IaaS  reuse for own services  okeanos: design

4. GRNET cloud overview GRNET: service ~okeanos; software synnefo ~okeanos is set to deliver IaaS – Compute (Virtual Machines) – Network (Virtual Networks, private Ethernets (L2) or public IPv4/6) – and Storage (Virtual Disks) / Pithos service Supports also project-like access for scientific computing 5K VMs, 2,2k users Synnefo: openstack compatible, uses google ganeti Details at okeanos.grnet.gr, trial at okeanos.io GRNET’s customers: IT depts of connected institutions, university students, researchers in academia Users manage resources over a simple, elegant UI, of a REST API, for full programmatic control Increasingly accepted in the European NREN community
