Use Cases of Nexus for Artifact Repository Management

1. Java Dependency Management in Java Projects

Java development is, to a great extent, dependent on managing dependencies when building complex and fully functional software. Nexus is a proxy for Maven Central or other remote repositories where build times and network overhead can be extensively reduced through dependency caching, provided that the dependencies are available locally. The organization can also control the flow of proprietary libraries and artifacts by hosting the internal repositories through Nexus, thus, the organization will make it easy to keep consistent and trustworthy artifacts across a project.

2. Docker Image Registry as storage for Containerized Application Images

As a result of containerization technologies becoming more widespread and popular, such as Docker, there is a central need for a registry where Docker images can be stored and managed. Nexus functions as an unrestricted Docker registry that stores, versions, and distributes Docker containers in the organizational infrastructure. The Docker Entities organization will allow DevOps groups to use Nexus as a Docker repository, which will reduce the complexity of application deployment, maintain version control, and utilize access control based on roles and permissions.

3. Continuous Integration and Delivery, referred to as CI/CD, Pipelines

Artifact repositories are crucial in speeding up the automated build, test, and deployment processes within the CI/CD workflow. Nexus integrates with a couple of CI/CD tools such as Jenkins, Bamboo, and TeamCity; thus, the publishing and consummation of artifacts can be automated as part of the CI/CD pipelines. Nexus is the key to setting up a central repository that will facilitate the team’s consistency and reproducibility in their builds, reuse artifacts, and provide a spirited delivery of software releases.

4. Lifecycle Management and Governance as a component of product

The best practices of software engineering are about the traceability and control of issues and defects of the components of the software, as this way security, compliance, and quality can be guaranteed. Nexus provides lifecycle management for components, with versioning, metadata management, and vulnerability scanning as its features, i.e. versioning, metadata management, and scanning for vulnerability. Consequently, policies can be set forth to monitor and detect old and unsecured components in order to execute preemptive actions for ameliorating risks.

5. Multi- and Hybrid Cloud environments

Managing artifacts across varied, hybrid, and even multi-cloud environments is a daunting task for those responsible for a distributed architecture. Nexus serves hybrid cloud deployments, by means of replicating and synchronizing artifact repositories across the existing on-premises and cloud channels as well. Via installing Nexus instances to various areas can be a solution for reducing latency and enhancing availability while providing the same access to the artifacts in all environment of deployments.

6. Secure Software Supply Chain

Keeping the security of software supply chain is the most important step to prevent supply chain attacks and provide completeness of software artifacts. Nexus incorporates with SCA scanning tools such as Sonatype Nexus Lifecycle and SonarQube and allows organizations to do automated SCA and license checks on artifacts.

Nexus is where software artifacts are kept, managed, and delivered easily to stakeholders. The repository is the secure and scalable platform for hosting both JAR files, Docker images, npm packages, and other artifacts created in the software development life cycle.
