Executive Summary: A researcher needs to create, read, update, and delete files and directories from one site at another using POSIX operations, e.g., creat, read, write, unlink. Note that “site” can refer to a resource provided by a service provider, a local campus, a research lab, a desktop computer, or even a home computer.
|Component||User facing?||Component’s role in the capability|
|Genesis II||yes||Provides both the user interface for accessing files in GFFS and the client and server software for GFFS services. May be installed on end user systems, campus systems, science gateway systems, or XSEDE login servers. Files to be accessed must be present in (“exported to”) one or more active (running) GFFS services. Files in GFFS can be accessed on any system with the Genesis II client installed and configured and network connectivity to the GFFS service.|
|Genesis II Secure Token Service (WS-Trust STS)||no||Translates XSEDE OAuth2 tokens (user identity, group membership) obtained from Globus Auth into the signed SAML chains required by the Genesis II client|
|Globus Auth||no||Provides the authentication and authorization services that issue XSEDE user credentials and group membership data, which is in turn used by WSTrust STS to generate credentials used by Genesis II client|
