Artifactory is essential for continuous delivery pipelines because it provides a central hub for storing, managing, and distributing build artifacts. It ensures that every artifact is version-controlled, traceable, and easily accessible during deployments. By integrating with CI/CD tools, Artifactory automates artifact promotion from development to production environments, reducing errors and manual handling. Its metadata tracking helps maintain visibility into dependencies, while checksum-based verification ensures artifact integrity. The caching of external packages speeds up builds, and REST APIs make integration effortless. This combination of automation, reliability, and traceability ensures faster, more consistent software delivery across teams.
