Transitioning from Jenkins X to Harness significantly reduced deployment time from over 90 minutes to just 5 minutes for an Nginx image on Amazon EKS, demonstrating Harness's efficiency in continuous delivery. Jenkins, a pivotal tool in the DevOps movement, originated from Hudson and introduced Continuous Integration to a wide audience. The article discusses the complexities and hurdles encountered when using Jenkins X, particularly in terms of installation issues and adapting to stringent GitOps models, which involve a steep learning curve. While Jenkins X is evolving by incorporating Tekton as its pipeline engine, the author highlights the challenges of learning new paradigms like GitOps when coupled with tool complexity. Despite these challenges, the author acknowledges the significant contributions of Jenkins to DevOps and expresses enthusiasm for exploring Jenkins X, while also appreciating Harness's ability to offer streamlined delivery processes without fully embracing the latest CNCF stack.
