Transitioning from Spinnaker to Harness streamlines the continuous delivery process by reducing setup complexity and maintenance costs, while emphasizing a templatized and reusable approach that lowers the administrative burden. Spinnaker's architecture involves over 11 microservices, each with specific resource requirements and intricate setup processes, including a separate installation and configuration management tool, Halyard. This complexity often leads to significant administrative efforts and hidden costs despite the platform being open-source. In contrast, Harness consists of only two main components, Manager and Delegate, and simplifies the installation and maintenance processes, promoting a more scalable and efficient deployment strategy. Harness emphasizes templating across its services, environments, and workflows, making it easier to manage and adapt while offering robust support through customer success teams, which further reduces the operational burden.
