5 GRNET mission GRNET is a state-owned company operating under the supervision of the Ministry of Development (General Secretariat of Research & Technology); non-profit Main mission is to provide high-quality electronic infrastructure services to the Greek academic and research institutions: National and international connectivity services Distributed Computing Infrastructure services (computing, storage, visualisation) Supporting activity is the promotion and dissemination of the use of ICT in the public and private sector towards an e-government, e- Learning and e-business environment Main sources of funding are the Operational Programme for the Information Society, Ministry of Economy and Finance and EC projects GRNET has been certified by ISO 9001:2000 in project management
6 Pan-EU e-infrastructures vision The Research Network infrastructure provides fast interconnection and advanced services among Research and Education institutes of different countries The Research Distributed Computing Infrastructure provides a distributed environment for sharing computing power, storage, instruments and databases through the appropriate software (middleware) in order to solve complex application problems This integrated networking & DCI environment is called electronic infrastructure (einfrastructure) allowing new methods of global collaborative research - often referred to as electronic science (escience) The creation of the einfrastructure is a key objective of the European Research Area e-science Collaborations Distributed Computing Infrastructure Network Infrastructure
7 National e-infrastructures vision GRNET was one of the first NRENs in Europe to expand its services to grid and computing in general Being infrastructure-oriented and application-neutral serving all user e- Science communities Adopting the EU e-infrastructure initiative: Integrated Networking & Distributed Computing Infrastructures; serviceoriented Source: European Commission DG INFSOM Unit F3: Research Infrastructures
8 Outline GRNET overview GRNET network Computing: Grid and High-Performance Computing Cloud developments: R&E and egovernement Regional integrations Pan-European integrations Worldwide integrations
9 GRNET main networking tasks Interconnects universities, research centers, academic organizations (>150), primary and secondary schools (15000) end-users Continuously upgrades the national backbone (Dark fiber backbone (Nx10 Gbps), institutions access (1 10 Gbps per institution) and international backbone (currently at 4*10 Gbps) Operates the GR Internet Exchange (GR-IX), peering of Greek commercial Internet Service Providers at 10Gbps each Cooperates with Greek and international research and academic institutions for the development of innovative networking services
10 GRNET network evolution: from GRNET2 to GRNET3 GRNET2: 2,5Gbps leased lambdas, 20M, GRNET3: dark fibre based, 10Gbps capable, 30M,

12 GRNET network evolution: from GRNET3 to GRNET4 GRNET3: dark fibres, 10Gbps capable, 30M, GRNET4: Equipment upgrades, 7.5M, Service Oriented Design Optical Services Layer: physical layer connectivity Carrier Services Layer: Carrier Ethernet (MPLS) interconnection IP Services Layer: IP interconnection among GRNET customers and the rest of Internet 40/100Gbps wavelengths based on PM-QPSK modulation
13 GRNET NOC Manages the network devices and servers Maintains services (network, computing, voice & video) Monitors the performance and the use of network resources Resolves problems that occur in the networking and computational equipment Establishes security rules for devices and services in the backbone network and to handle security incidents Develops tools and additional services Monitor the adaptation of the network's acceptable use policy and procedures affecting it Produce documentations and reports Designs new network services Evaluates software or technologies of interest 13
14 Outline GRNET overview GRNET network Computing: Grid and High-Performance Computing Cloud developments: R&E and egovernement Regional integrations Pan-European integrations Worldwide integrations

83 Cloud MINEDU snapshots
84 Cloud for R&E: Why? STUDENT- It gives me the opportunity to test different kinds of software on a machine that I no longer need after my work is done PROFESSOR - It makes it possible for me to deploy PC labs without having to worry about specific hardware or physical space. It makes me capable of providing machines to my students for a scheduled amount of time. It gives me storage space to upload content and to share data with my students or access them through my virtual hardware RESEARCHER- It enables me to run experiments in many different environments and network topologies which I can provision easily, quickly and dynamically. I can have persistent or volatile machines according to my needs. I can also upload (besides my files) my own Images and launch Virtual Machines from them Next step: Cloud for egovernement?
85 Current government IT status Multiple small-to-medium Information Systems scattered in Public Sector Many computer rooms / server rooms Under-used Devalued very fast Need specialized personnel (administration) High energy consumption 300m for server hardware during Operational Program Information Society Redundant computing power cannot be utilized Since there is no money for new equipment New Applications cannot be delivered to Public Sector No New Applications for Citizens
86 G-cloud development strategy (1) Phase 1: Virtualize everything Old physical systems are converted to VMs New system needs are covered from current physical machines Machine 1 VM 1 VM 2 VM 3 Needed Machine #1 Needed Machine #2 same hardware
87 G-cloud development strategy (2) Phase 2: Build few but BIG G-Data Centers Utilize virtualisation Since old systems are already VMs (1 st Step) are easily migrated to G-Data Centers New systems are created as VMs from the beginning Benefits: Reduced administration needs/costs Easier migration and disaster recovery procedures Improved energy efficiency Rapid development of new services Low services downtime
88 G-cloud development strategy (2) VM 1 VM 1 New VM VM 2 VM 3 OLD SYSTEM Needed New System VM 2 VM 3 SPACE FOR MANY VIRTUAL MACHINES SPACE FOR MANY VIRTUAL MACHINES SPACE FOR MANY VIRTUAL MACHINES NEW G-DATA CENTER
89 G-cloud development strategy (3) Phase 3: Share software, licenses, storage Sharing Software (eg. 2 Apps share same DBMS for non-critical systems) Sharing Licenses (eg. 2 Apps share same DBMS license) Sharing Storage (eg. Apps utilize space from common storage array)
90 G-cloud: policy background A MoU has been signed among all players (GRNET, Infosoc SA, Ktimatologio, Management Organization Unit, General Secretariat of Information Systems, and others) to define the national policy on government cloud computing. This team led by the Cabinet Office (included representatives from over 10 Government departments) set out to define how the public sector could utilize the Cloud Computing approach to ICT delivery and explore what benefits and challenges this approach would create. Open call from Information Society Operational Program of 15ME InfoSoc to build G-cloud

107 Conclusion: Cloud for R&E - advantages for Latin America (1) Economies of scale for the community Minimizes the investment in equipment and support contracts Infrastructure, staff Solving understaffing problems, problems with QoS, maintenance
108 Conclusion: Cloud for R&E - advantages for Latin America (2) Grid resources sharing built the community and the culture CLARA as the centre of gravity Keeps supporting the regional collaborations and know-how Grid operations a very good step towards computing for research, should be supported further (MoU signed in Mexico City this Friday! CLARA support needed) Potential cloud services as a step ahead in terms of flexibility, manageability Greek national model comparable to CLARA potential model
