Using Grids is not straightforward 

Some barriers in the adoption of Grids:


Changes on Grids means changes on applications
Time required to adapt usual workflows
Lack of structure to support anonymous access
Download and installation of applications
Interface
Slow to get to compared to other resources
Difficult to use in the beginning
Time spent to get the application compiled and
running

The path to technology uptake –
Where are we with e-Infrastructures ?

Interoperability –
Does this definition apply to e-Infrastructures ?

Interoperability is a property referring to the ability of
diverse systems and organizations to work together
(inter-operate). The term is often used in a technical systems
engineering sense, or alternatively in a broad sense, taking
into account social, political, and organizational factors that
impact system to system performance;

According to ISO/IEC 2382-01 (Information Technology
Vocabulary, Fundamental Terms), interoperability is "The
capability to communicate, execute programs, or
transfer data among various functional units in a
manner that requires the user to have little or no
knowledge of the unique characteristics of those units".

The CHAIN Worldwide Interoperability Demo
(http://science-gateway.chain-project.eu)

To demonstrate that:

e-Infrastructures can be made interoperable to
each other at user application level using
standards
 with the meaning of interoperability given
above;

VRC-specific applications can be submitted from
anywhere and run everywhere

Some considerations…

About 1 billion people have accounts on the
existing Social Networks (many of the
researchers we are targeting with eInfrastructures are among them)

Web-based social networking accounts for
more than 10-15% of the total time spent
online in the whole world

Social Networks’ are by far the most used
(liked) virtual environments in the world

Summary and conclusions

e-Infrastructures can be very beneficial platforms for many users,
provided they are really «easy to use» and users are at their centre

The Catania Science Gateway framework, with support for Identity
Federations changes the way Grid infrastructures are used, hugely
widening their potential user base across continents and organisations,
especially non-IT experts and the “citizen scientist”

The adoption of standards (JSR 286, SAGA, SAML, etc.) represents a
concrete investment towards sustainability

The CHAIN worldwide interoperability program demonstrated that,
through Science Gateways based on standards, users can really access
global e-Infrastructures in a seamless and ubiquitous way independently
of the underlying middleware (local, grid, cloud)

We propose to use the same approach in CHAIN-REDS to gather
distributed resources from all over the region and the world and get a
truly global e-Infrastructure, yet respecting local specificities and
exploiting competences of all participating organisations
