Oceanos and synnefo - clouds for global R&E

1. Dr. Ognjen PrnjatEuropean and Regional eInfrastructure managementGreek Research and Technology Network Oceanos and synnefo - clouds for global R&E eAge 2103 Conference, Tunis

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. okeanos: design • Commercial IaaSvs 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 reusefor own services

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

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

10. Cloud Infrastructure: Data Centers • Data Center 1 (NDC) • Status – Production operation • Location – National Documentation Center, Athens, Greece • Purpose –Central PoP of GRNET, Connection to GEANT, GR-IX, Cloud&Grid. Mainly networking • Number of Racks - 16 • Total Power – 110KW with N+1 redundancy • Data Center 2 (MINEDU) • Status – Production operation • Location – Ministry of Education Athens, Greece • Purpose – Cloud/HPC services • Number of Racks - 28 • Total Power – 450KW with N+1 redundancy • Data Center 3 (LOUROS) • Status – Design phase • Location – Hydroelectric Plant of Louros • Purpose – GRNET disaster recovery for cloud/HPC services, GREEN Data Center, PUE<1.3 • Number of Racks - 14 • Total Power – 250KW with N+1 redundancy
