Abstract
The development of data management services capable to cope with very large data resources is a key challenge to allow the future einfrastructures to address the needs of the next generation extreme scale scientific experiments. To face this challenge, in November 2017 the H2020 eXtreme DataCloud - XDC project has been launched. Lasting for 27 months and combining the expertise of eight large European research
organisations, the project aims at developing scalable technologies for
federating storage resources and managing data in highly distributed
computing environments. The targeted platforms are the current and next
generation e-Infrastructures deployed in Europe, such as the European
Open Science Cloud (EOSC), the European Grid Infrastructure (EGI), and
the Worldwide LHC Computing Grid (WLCG). The project is use-case
driven with a multidisciplinary approach, addressing requirements from
research communities belonging to a wide range of scientific domains:
High Energy Physics, Astronomy, Photon and Life Science, Medical
research. XDC is aimed at implementing data management scalable
services, combining already established data management and
orchestration tools, to address the following high level topics: policy
driven data management based on Quality-of-Service, Data Life-cycle
management, smart placement of data with caching mechanisms to reduce
access latency, meta-data with no predefined schema handling, execution
of pre-processing applications during ingestion, data management and
protection of sensitive data in distributed e-infrastructures, intelligent data
placement based on access patterns. This contribution introduces the
project, presents the foreseen overall architecture and the developments
that are being carried on to implement the requested functionalities.
