Technology and Inter-continental Services

1. Regional Operation Centres (ROCs)

CHAIN-REDS is in the process of enabling 5 Regional Operations Centres around the world to both technically and procedurally interoperate with the European Grid Infrastructure.
Regional Operations Centres (ROCs) represent hubs for operations of the Grid computing sites present in a region, and they act as points of technical communication between the regions and the European Grid Infrastructure. These centres are set up and maintained by the regions themselves independently of the CHAIN-REDS project, while the project itself facilitates their interoperation with their European counterpart and supports the use and adoption of European technologies and approaches.
On the technical level, operational fields such as monitoring, helpdesks, accounting, etc. have been tackled for 5 Regional Operations Centres. Currently, the Africa and Arabia ROC and the South-East Asia ROC have been supported to a fully mature level in terms of operational capabilities; whereas China ROC and Latin America ROC are stable, and actions on improvements are ongoing. India/Garuda ROC is a stable ROC acting as a peer infrastructure provider with European Grid Infrastructure, where a number of technical fields are being currently harmonised.
On the policy level, 4 Memoranda of Understanding (MoUs) have been signed with direct support and facilitation provided by the CHAIN-REDS project, defining the framework for long-term persistent collaboration between EGI and the other regional Grids. The four MoUs have been signed between EGI and Africa&Arabia ROC, China, India and Latin America and they have been widely disseminated: examples are provided in the following news:

2: Global Cloud Testbed

CHAIN-REDS has built an inter-continental Cloud testbed to demonstrate standard-based cloud interoperability and interoperation and to provide a platform where to run domain-specific and general-purpose applications. The CHAIN-REDS Cloud test-bed has been organised as a “virtual cloud” made up by the resources belonging to 10 sites from 6 countries, of which 1 owned by an SME located in Egypt. 4 out of the 10 sites are also belonging to the EGI Federated Cloud and 3 different and well-known cloud stacks are supported, namely Okeanos, OpenNebula and OpenStack.
The CHAIN-REDS Cloud testbed, whose actual configuration is reported on in, is managed by a specific service, a Cloud Orchestrator, integrated in the CHAIN-REDS Science Gateway (SG), which is called MyCloud and uses the CLoud-Enabled Virtual EnviRonment (CLEVER) software package to orchestrate the cloud services through their OCCI-compliant and rOCCI-enabled interfaces.

3. Science Gateways

CHAIN-REDS is committed to foster the adoption of the Science Gateway (SG) paradigm in all the regions addressed by the project since Science Gateways represent valuable platforms to: (i) seamlessly access various e-Infrastructures in a way that is transparent for end-users and (ii) support the so-called “long tail of science”.
CHAIN-REDS has promoted and supported the creation of the EU-project-specific SGs such as agINFRA’s, DCH-RP’s, EarthServer’s, eI4Africa’s and the country SGs in Algeria, Jordan, Italy, Mexico, Morocco, South Africa and soon in Tanzania and Zambia.
The total number of users registered in the SGs promoted and supported by CHAIN-REDS is above 1,000 and the current number of applications integrated in Science Gateways is 25, both domain specific and general-purpose.

4: Knowledge Base

The CHAIN-REDS Knowledge Base (KB) is one of the most complete sources of information about e-Infrastructures and related services. Whenever and wherever possible, data are automatically updated from external references (e.g., EGI GOCDB) or taken from official documents, such as the Annual Compendia of ASREN, RedCLARA, TERENA and the UbuntuNet Alliance.
In this context the CHAIN-REDS KB has been extended to include Open Access Document Repositories (OADRs) and Data Repositories (DRs). As of today, the KB contains about 2,500 OADRs and 600 DRs, out of which about 100 have been included thanks to the promotion and outreach activities carried out by the project and to the collaborations with stakeholders such as DataCite and eIFL. The total number of resources that are indirectly included in the KB is well above 30 million.
By the time of the second CHAIN-REDS review, several hundred of new repositories will be added to the KB thanks to the collaboration of the Ranking Web of Repositories (

5: eduroam and Identity Federations

The CHAIN-REDS supports the eduroam deployment as the best and easiest way to promote the benefits of Identity Federations (IdF). “Simple” identity management is seen as the basic building step both for eduroam and IdF approaches. CHAIN-REDS focuses on both the technological components needed for the deployment (taking specifically care of the “easiness to use”, as with Radius and Perun appliances, presenting also Perun as a simple-to-use-component for Identity Management) as well as on the promotion and actual deployment of the services (also in collaboration with other initiatives)).
With the CHAIN-REDS support, the promotion of eduroam started in Arab countries (to be followed by actual deployment in the next period); in the sub-Saharan Africa CHAIN-REDS supported eduroam deployment or identity consolidation (identity management) in Kenya, Zambia and South Africa. India is already connected to eduroam. In the Asia-Pacific region Macau, Singapore and Thailand are connected, while CHAIN-REDS supported the deployment in Malaysia and is collaborating with Taiwan and Indonesia colleagues to support their eduroam-related activities. There is also a pilot eduroam setup in China, in particular at the Peking University. In Latin America most of the technical work is done within the ELCIRA project, 8 countries have eduroam in production and 4 countries have pilot deployment, CHAIN-REDS works with individual institutions to support their connection to the eduroam infrastructure and currently it also helps Colombia to define its eduroam infrastructure.

More extensive information is available in the published deliverable D5.3 “eduroam and Identity Federations—the World Status Report”.

6. Data Accessibility, Reproducibility and Trustworthiness (DART)

CHAIN-REDS has implemented, fully based on standards and established components, a complete data workflow that allows any user and/or collaboration to search and access Data Repositories and Open Access Document Repositories, extract datasets from them, seamlessly access the project Science Gateway by Identity Provision, use the previously selected datasets as an input of a code already running via the Science Gateway on diverse e-Infrastructures, collect the results and, if requested, store them with a Persistent Digital Identifier (PID) for a future use.

Three promotional videos related to DART have been recorded by the project: a short introductory one (3 min), a technical one (5 min), and several tutorials (3*10 min). All  videos can be watched on the CHAIN-REDS YouTube channel.
