Jenkins, a stalwart in continuous integration for over two decades, is increasingly seen as outdated in the face of modern cloud-native and scalable software delivery demands. Originally designed for simpler workflows and a virtual machine-dominated environment, Jenkins now struggles with the complexities of modern applications, plugin chaos, pipeline sprawl, and governance gaps. Migrating off Jenkins is challenging due to its deep plugin dependencies, unique pipelines, and cultural resistance, but offers an opportunity to modernize CI/CD strategies with platforms like Harness. Harness simplifies the transition with features like automated pipeline conversion, a Kubernetes-native architecture, built-in governance, and AI capabilities for continuous improvement. The case of Ancestry.com illustrates the benefits of such a migration, including reduced maintenance effort, increased deployment frequency, and decreased downtime. Embracing newer platforms not only addresses the limitations of Jenkins but also positions organizations for future success in software delivery.
