Description: Nexus provides infrastructure and services for organizations that use repository managers to obtain and deliver software. This software is an internal repository manager used to proxy remote repositories and share software artifacts required for development. Developers can upload artifacts, such as build dependencies, using the Nexus interface, or deploy artifacts to hosted repositories using Maven. Nexus allows developers to manage binary software components through the software development lifecycle and can control component releases with rules and add automated notifications. This technology is a server application with a web-based user interface.

This entry covers the three distributions of Nexus: Nexus Open Source, Nexus Professional, and Nexus Professional Plus. Nexus Open Source is a repository manager that can be freely used and customized. Nexus Professional is a fee-based distribution of Nexus with features that are relevant to large enterprises and organizations, which require complex procurement and staging work-flows in addition to more advanced Lightweight Directory Access Protocol (LDAP) integration, Atlassian Crowd support, and other development infrastructure. Nexus Professional Plus fee-based edition includes all Nexus Professional features and additional functionality for policy automation, policy alerts, and component version evaluations.

The TRM decisions in this entry only apply to technologies and versions owned, operated, managed, patched, and version-controlled by VA. This includes technologies deployed as software installations on VMs within VA-controlled cloud environments (e.g., VA Enterprise Cloud (VAEC)). Cloud services provided by the VAEC, which are listed in the VAEC Service Catalog, and those controlled and managed by an external Cloud Service Provider (i.e., SaaS) are not in the purview of the TRM. For more information on the use of cloud services and cloud-based products within VA, including VA private clouds, please see the Enterprise Cloud Solutions Office (ECSO) Portal at:
