The European CHAIN-REDS project, which ran for 30 months starting in December 2012, worked to promote and support technological and scientific collaboration across e-infrastructures established and operated in different continents, in order to define a path towards a global e-infrastructure ecosystem. The CHAIN-REDS vision is that this ecosystem will enable virtual research communities, research groups, and even individual researchers to access and efficiently use worldwide distributed resources (e.g., computing, storage, data, services, tools, and applications). A booklet published last month gives an overview of the project’s success in facilitating this ambitious vision and assesses the project’s global impact.
