The IWSG 2019 - 11th International Workshop on Science Gateways was held at the
University of Ljubljana, Slovenia, from 12th to 14th June 2019. It brought together 32
researchers, scientists and developers from diverse research domains.

Science Gateways are a community-specific set of tools, applications, and data collections that
are integrated together via a Web portal or a desktop application, providing access to resources
and services of Distributed Computing Infrastructures (DCIs). Nowadays, computing resources
that may be used in Science Gateways go beyond the usual Grid. Computing resources such as
the hybrid Cloud (Cloud, Fog, Edge), the Internet of Things (IoT) and various off-the-shelf
methods of Artificial Intelligence (AI) may be readily used for scientific applications.
Additionally, technologies such as Blockchain and Smart Contracts may be used for secure
aggregation of resources for scientific work at an unprecedented large scale.
Science Gateways offer the potential to open the utilisation of DCIs to wider audiences by
providing a customised and easy to use user interface to access large computational and data
resources. The complexity of the underlying infrastructure can be completely hidden from the
end-users by a suitably tailored interface. As interest in Science Gateways has accelerated in
the past few years, there is an increasing number of new user communities in practically all
possible areas of scientific interest.

The workshop included three thought-provoking keynotes, presentations of 12 full papers
reproduced in this issue, 11 short presentations and an open discussion. It showed intense
engagement in a very wide range of research issues pertinent to science gateways such as novel
approaches with AI, Edge Computing, enhanced data management and technologies as well as
topics focusing on impact, metrics and sustainability. The use cases highlighted the aspect of
science gateways as community-driven environments for researchers and educators.
