# Aviation Customer Story — 50% AWS cost savings **Industry:** Aviation **Cloud:** AWS **Outcome:** 50% AWS cost savings ## Summary Major airport authority workloads migrated with seamless auto-scale. ## The Challenge An Asia-Pacific airport authority operated a mission-critical legacy application that had been in production for years — heavily customized, sparsely documented, and tightly coupled to aging hardware. The system underpinned daily airport operations, so any disruption carried direct business and passenger impact.Leadership wanted to migrate to AWS to gain elasticity and cost control, but a full microservices rewrite was off the table given timeline, risk, and the lack of original design documentation.They needed a path that would deliver cloud scalability and cost efficiency without rearchitecting the application — and without taking the airport offline to do it. ## The Solution CloudHedge applied automated containerization to lift the existing application into containers as-is, then redeployed it on AWS behind managed orchestration. There was no rewrite and no architectural overhaul — the application's behavior, integrations, and operational profile were preserved end-to-end.CHAI Flow orchestrated the discovery, packaging, environment replication, and deployment automation, allowing the team to mirror the existing production configuration in AWS before cutover. That replication was the key to de-risking what would otherwise have been a high-stakes migration.The result was a modernization approach that gave the airport authority cloud-native operational characteristics — elastic scale, automated deployments, reduced hardware dependency — without the cost or risk of a greenfield rebuild. ## The Outcome The migration delivered 50% overall cost savings across hardware, support, maintenance, and personnel, with an additional 60% reduction in operational costs driven by automation. Application scaling now happens in minutes instead of the previous procurement-bound timeframes.Cutover was seamless, with uninterrupted operations for the airport, and the new footprint dramatically reduced reliance on physical hardware and the energy needed to run it — a quiet but meaningful sustainability win. ## Stack - AWS - Docker - Kubernetes - CHAI Flow ## Contact Book a demo: /contact/ Email: hello@cloudhedge.io
