Abstract State-of-the-art gateways are connected to several distributed computing
infrastructures (DCIs) that are able to run jobs and workflows simultaneously in all
those different DCIs. Data of e-Science applications might be stored on different
storage resources, making it dif
cult for various user communities to browse,
access, or update it. This chapter presents the Data Avenue concept and related
tools that aim at hiding technical details of accessing different storage resources,
and providing an easy-to-use
file browsing interface to manage, upload and
download, and even transfer data between different types of storage resources.
Usage scenarios to exploit Data Avenue services as well as security considerations
are discussed.
5.1 Introduction
Numerous storage solutions have been evolved during the past decades, which are
actively used today in distributed computing environments. Besides the conven-
tional HTTP/FTP servers, storage resources accessible over Secure File Transfer
