Single Digits successfully transitioned from a legacy deployment process to a modern microservice architecture using Harness, significantly improving their deployment efficiency and reducing costs. Initially, the legacy system required a complex and time-consuming deployment process, taking 6 hours every two weeks and involving off-hours sessions to minimize downtime risks. The adoption of Harness enabled Single Digits to reduce the deployment time to 20 minutes, saving $108,000 annually. Over 125 services have been onboarded, enhancing deployment velocity and minimizing downtime. The transition was spearheaded by Clint Nelissen, Director of Cloud Architecture, who sought a solution that would integrate with existing CI work without requiring a complete overhaul. Harness provided the necessary support to facilitate the migration, making software delivery a streamlined part of their modernization efforts.
