How to Remove the Major Obstacle of Legacy Modernization: Risk

OpenLegacy + Amazon Web Services:
Better together
Transform Your Core. Accelerate Your Future on AWS.
Risk-Free, Agile Mainframe Modernization to the Cloud with OpenLegacy - Move 10x Faster.
Reduce Costs by 45%. Zero Business Disruption. OpenLegacy delivers proven business results
at a speed that manual rewrites cannot match. With an 8-10x increase in migration velocity,
organizations can move from assessment to a production-ready pilot in just 2 to 4 weeks.
This speed is backed by a validated 353% ROI as recognized by the AWS Mainframe Modernization Competency.
The "Dual Factory" Modernization Model
OpenLegacy is the only platform that offers a simultaneous two-pronged strategy: an Integration Factory and a Migration Factory. While the Integration Factory rapidly creates APIs to support immediate digital innovation (augmentation), the Migration Factory refactors legacy code into AWS-native microservices. This allows enterprises to innovate today while systematically migrating core workloads for tomorrow.
Middleware-Free Native Integration
Unlike traditional solutions that rely on complex, high-latency middleware (such as ESBs, MQ, or CTG), OpenLegacy uses direct native access to the legacy core (COBOL, CICS, IMS, and IBM i). By bypassing these fragile layers, OpenLegacy eliminates the "middleware tax," significantly reduces mainframe processing costs, and improves overall system performance.
Risk-Free Coexistence Strategy
OpenLegacy eliminates the "Big Bang" migration risk by enabling Side-by-Side Coexistence. Legacy systems and new AWS-native services run in parallel with 100% functional parity. This incremental, phased approach ensures zero business disruption and provides a permanent safety net, allowing the organization to cut over to the cloud one service at a time.
Automated "Cloud-Native" Code Generation
Instead of using proprietary runtimes or "black-box" emulators, OpenLegacy automatically extracts business logic and transforms it into standard, contract-first Java or Node.js. This creates truly cloud-native code that can run on AWS Lambda or EKS and be maintained by modern DevOps teams, effectively solving the "skills gap" created by the retiring mainframe workforce.
Redefining The Journey
