Executive Summary: An L1 or L2 service provider needs to use groups to control access to his/her resource. The most common reason is to limit access to the resource to project groups that have active allocations via an official allocation process.
|Component||User facing?||Component’s role in the capability|
|AMIE||no||A secure messaging service that is used to share individual user identity information and XSEDE group definitions between XCDB and individual SP resources and accounting systems.|
|XSEDE Central Database (XCDB)||no||The repository that stores XSEDE user profile data for individuals and XSEDE group definitions. Group definitions are currently used only for two purposes: XSEDE staff membership (for access to staff tools) and allocation project memberships (for permission to use resources associated with a project allocation).|
|XSEDE User Portal (XUP)||yes||The front-end (web browser-based) user interface to the XSEDE system where individuals register with XSEDE, manage their user profile information, request allocations to use XSEDE SP resources, and manage membership in projects that have active allocations.|
