About the DCI ITS offers a core set of services that include: News, Email(IMAP), Web Publishing, and Research facilities (statistical, Scientific, and BioScientific). These services are built on top of the Distributed Computing Infrastructure (DCI). The DCI is the name of ITS's customized distributed computing environment. Most of the services that ITS provide use this environment to pool their resources. As in any distributed computing environment, the bottom layer of the DCI is the network. Certain core components of the DCI sit on top of the network, they are: AFS, Kerberos, and License Management. AFS is a file system that uses the network to allow users to abstract files residing on different machines to one universal file system. Kerberos is the mechanism that the DCI uses to authenticate its users. License management is the structure that allows university licensed binaries (residing in AFS space) to be run by affiliates of the university. Two higher level components sit on top of these four core components; they are Userid Management and Shared Applications. Different services sit on top of different components of the DCI. The campus email (IMAP) server uses Kerberos authentication to allow DCI users to view and send email. Research services use shared applications such as SPSS, SAS, and Mathematica whose binaries are stored in AFS space, and controlled by License Management software. Now these services are being extended out to the public so that UNC's general computing community can take advantage of the DCI.
