Tag management in Harness is a feature that enhances Continuous Delivery by allowing developers to organize, search, and filter application components such as services, environments, and pipelines, which aids in better cost allocation and resource management. Tagging is a widely-used method across various software tools, not just in DevOps, for managing data complexity by categorizing it into logical components. As application environments and development teams grow, so does the need for effective tagging to manage complexity, economic constraints, and various cloud strategies. Harness's tagging capabilities enable users to categorize components by team, mark them for reuse, preservation, or deletion, and allocate costs effectively. The tagging feature, which can be configured in the Harness setup, allows users to create and manage tags for supported components, facilitating a better understanding of applications and strategies. Future enhancements are planned to expand the tagging capabilities further, reflecting the dynamic needs of businesses in organizing their development processes.
