GitOps leverages Git as the central source of truth for cloud-native application deployments, enhancing developer experience through declarative infrastructure, automated change application, and self-healing capabilities. Harness GitOps-as-a-Service builds upon these principles by integrating enterprise-grade security and governance, facilitating scalable and efficient software delivery, and is based on the open-source Argo CD project. GitOps allows for a streamlined and standardized deployment process where desired application states are managed through version control, enabling automated, reliable, and fast deployments. The approach addresses challenges of traditional deployment methods by providing a single source of truth, reducing manual processes, and enhancing developer efficiency. Harness adds value by offering features like pull request pipelines, a centralized management interface, and a comprehensive audit log, helping to manage the complexities and scale of GitOps implementation across multiple environments and applications.
