Synnefo
Synnefo is a complete open-source cloud stack written in Python that provides Compute, Network, Image, Volume and Storage services, similar to the ones offered by AWS. Synnefo manages multiple Google Ganeti clusters at the backend that handle low-level VM operations and uses Archipelago to unify cloud storage. To boost 3rd-party compatibility, Synnefo exposes the OpenStack APIs to users. Synnefo is being developed by GRNET (Greek Research and Technology Network), and is powering two of its public cloud services, the service, which is aimed towards the Greek academic community, and the service, which is open for all members of the GÉANT network. History In November 2006, in an effort to provide advanced cloud services for the Greek academic and research community, GRNET decides to launch a cloud storage service, similar to Amazon's S3, called Pithos. The project is outsourced and opens for public beta to the members of the Greek academic and research community in May 200 ...

Greek Internet Exchange
The Greek Internet Exchange (GR-IX) is an Internet exchange point located in Athens and Thessaloniki in Greece. It was founded in 2009 in order to replace the Athens Internet Exchange as the principal Internet Exchange Point in Greece, which was achieved in January 2010. GR-IX is non-profit, independent and is supervised by the Greek Research and Technology Network (GRNET). GR-IX is a member of the European Internet Exchange Association. History The predecessor of GR-IX, Athens Internet Exchange (AIX) was created by GRNET in 1997, to provide interconnection services between the Greek ISPs. By the late 1990s, the way AIX was set up was not completely satisfactory to the member ISPs: since AIX was located in Hellenic Telecommunications Organization (OTE) facilities, providers had to lease lines from OTE in order to connect to AIX. Additionally, ISPs had the right to charge other members for exchanged traffic, a right sometimes overused by the larger providers. To deal with these i ...

National Research And Education Network
A national research and education network (NREN) is a specialised internet service provider dedicated to supporting the needs of the research and education communities within a country. It is usually distinguished by support for a high-speed backbone network, often offering dedicated channels for individual research projects. In recent years NRENs have developed many 'above the net' services.

Athens
Athens ( ; el, Αθήνα, Athína ; grc, Ἀθῆναι, Athênai (pl.) ) is both the capital and largest city of Greece. With a population close to four million, it is also the seventh largest city in the European Union. Athens dominates and is the capital of the Attica region and is one of the world's oldest cities, with its recorded history spanning over 3,400 years and its earliest human presence beginning somewhere between the 11th and 7th millennia BC. Classical Athens was a powerful city-state. It was a centre for the arts, learning and philosophy, and the home of Plato's Academy and Aristotle's Lyceum. It is widely referred to as the cradle of Western civilization and the birthplace of democracy, largely because of its cultural and political influence on the European continent—particularly Ancient Rome. In modern times, Athens is a large cosmopolitan metropolis and central to economic, financial, industrial, maritime, political and cultural life in Gre ...

GÉANT
GÉANT is the pan-European data network for the research and education community. It interconnects national research and education networks (NRENs) across Europe, enabling collaboration on projects ranging from biological science, to earth observation, to arts and culture. The GÉANT project combines a high-bandwidth, high-capacity 50,000 km network with a growing range of services. These allow researchers to collaborate, working together wherever they are located. Services include identity and trust, multi-domain monitoring perfSONAR MDM, dynamic circuits and roaming via the eduroam service. Together with European NRENs, GÉANT connects 50 million users in over 10,000 institutions. Through links to research networks in other regions (such as Internet2 and ESnet in the US, AfricaConnect in Africa, TEIN in Asia-Pacific and RedCLARA in Latin America), GÉANT enables collaboration between researchers in over half the world's countries. Co-funded by the European Commission an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IaaS
The first major provider of infrastructure as a service (IaaS) was Amazon in 2008. IaaS is a cloud computing service model by means of which computing resources are supplied by a cloud services provider. The IaaS vendor provides the storage, network, servers and virtualization (which mostly refers, in this case, to emulating computer hardware). This service enable users to free themselves from maintaining an on-premise data center. The IaaS provider is hosting these resources in either a public cloud (meaning users share the same hardware, storage, and network devices with other users), private cloud (meaning users does not share these resources), or hybrid cloud (combination of both). It provides the customer with high-level APIs used to dereference various low-level details of underlying network infrastructure like backup, data partitioning, scaling, security, physical computing resources, etc. A hypervisor, such as Xen, Oracle VirtualBox, Oracle VM, KVM, VMware ESX/ESXi, or ...

Internet Service Provider
An Internet service provider (ISP) is an organization that provides services for accessing, using, or participating in the Internet. ISPs can be organized in various forms, such as commercial, community-owned, non-profit, or otherwise privately owned. Internet services typically provided by ISPs can include Internet access, Internet transit, domain name registration, web hosting, Usenet service, and colocation. An ISP typically serves as the access point or the gateway that provides a user access to everything available on the Internet. Such a network can also be called as an eyeball network. History The Internet (originally ARPAnet) was developed as a network between government research laboratories and participating departments of universities. Other companies and organizations joined by direct connection to the backbone, or by arrangements through other connected companies, sometimes using dialup tools such as UUCP. By the late 1980s, a process was set in place towa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
