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 Mo. U 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, Iaa. S, and then Paa. S&Saa. S – Paving the way to public sector • Funding: 2. 2 ME Data Centres; 4. 5 ME s/w and services

okeanos: design • Commercial Iaa. S vs own Iaa. S? • Commercial Iaa. S – Amazon EC 2 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 Iaa. S reuse for own services

GRNET cloud overview • GRNET: service ~okeanos; software synnefo • ~okeanos is set to deliver Iaa. S – Compute (Virtual Machines) – Network (Virtual Networks, private Ethernets (L 2) or public IPv 4/6) – and Storage (Virtual Disks) / Pithos service • Supports also project-like access for scientific computing 5 K VMs, 2, 2 k 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 • •

cloud storage - Pithos • Online storage for all Greek academic and research community • 100 GB/user; files, groups • Access by web browsers, native test apps, i. Phone, Android • Open source implementation of Open. Stack object storage (REST API) • Also used in ~oceanos: – Stores custom and user-created images – Plankton provides image registry over pithos
