  A joint project between the Canadian Astronomy Data Center of the National
Research Council Canada, and the italian Istituto Nazionale di
Astrofisica-Osservatorio Astronomico di Trieste (INAF-OATs), partially funded
by the EGI-Engage H2020 European Project, is devoted to deploy an integrated
infrastructure, based on the International Virtual Observatory Alliance (IVOA)
standards, to access and exploit astronomical data. Currently CADC-CANFAR
provides scientists with an access, storage and computation facility, based on
software libraries implementing a set of standards developed by the
International Virtual Observatory Alliance (IVOA). The deployment of a twin
infrastructure, basically built on the same open source software libraries, has
been started at INAF-OATs. This new infrastructure now provides users with an
Access Control Service and a Storage Service. The final goal of the ongoing
project is to build an integrated infrastructure geographycally distributed
providing complete interoperability, both in users access control and data
sharing. This paper describes the target infrastructure, the main user
requirements covered, the technical choices and the implemented solutions.
