The TIER Reference Architecture assists executive stakeholders, campus IT architects and TIER community members in understanding the functional components for identity and access management in a higher education institution, and how those components relate to one another.
TIER’s Business Context
The TIER Architecture simplifies campus processes and advances inter-institutional collaboration and research through an open-source toolset and a set of campus architectural practices that answer the challenges posed by identity and access control at higher education institutions. The TIER Architecture provides tools, software and architectural patterns that enable institutions to effectively and securely manage access to institutional resources and to foster inter-institutional collaboration.
