Key Results
2X faster modernization, delivering 100% faster app modernization compared to traditional approaches.
25,000+ human hours saved through automation, eliminating months of manual engineering effort.
75% reduction in modernization time, completing in 2.5 months what would have taken 24+ months manually.
64+ microservices extracted from a monolithic legacy application.
25-year-old Windows app transformed into a cloud-native, Kubernetes-ready architecture.
The Situation
A U.S. government technology services provider supports mission-critical technology for the US Department of Defense. At the heart of one of their key programs sat a 25-year-old legacy .NET Windows application, a complex logistics system that had been built, patched, and extended over more than two decades.
The application worked. But it was showing its age. It couldn’t scale the way modern cloud-native systems can. It was difficult to update. And critically, there was no documentation and limited institutional knowledge about how the system was built.
The Real Problem
Modernizing a 25-year-old monolith is hard enough when you have a full blueprint. Without documentation or deep knowledge of the codebase, the challenge multiplies.
A traditional manual approach would have taken 24+ months and massive engineering investment. For a defense environment with strict security and compliance requirements, that timeline introduced unacceptable risk. Every month the legacy app stayed in place was another month of mounting technical debt, limited agility, and growing vulnerability.
The team needed a way to modernize fast, modernize safely, and modernize without rewriting the entire application from scratch.
How CHAI™ Changed the Equation
CloudHedge’s CHAI™ platform brought automation and intelligence to a problem that would have overwhelmed a manual approach.
Analyze. CHAI™ performed deep analysis of the legacy Windows application, mapping its architecture, dependencies, and components even without existing documentation. The platform reverse-engineered what years of institutional knowledge had failed to capture.
Decompose. CHAI™ automatically identified the right boundaries for breaking the monolith apart, extracting 64+ discrete microservices from a single tightly coupled application. What would have required months of architecture workshops and manual code analysis was completed in a fraction of the time.
Modernize & Deploy. CHAI™ transformed the legacy .NET application into cloud-native microservices running on Kubernetes on AWS. The entire modernization, from planning to design to implementation, was completed in just 6 months.
The Outcome
A software engineering leader at the firm’s public sector innovation office described migrating a 20+ year old .NET application to AWS “in a matter of weeks, from Planning to Design to Implementation” as becoming a reality with CHAI™.
A 25-year-old Windows monolith became 64+ cloud-native microservices. 25,000+ hours of manual effort were eliminated. And a modernization that would have stretched past two years was delivered in six months, with 75% time savings and 2X the speed of traditional approaches.
For a US Department of Defense program, that speed didn’t come at the cost of rigor. The modernized application met every security and compliance requirement, now running on a scalable, maintainable Kubernetes architecture built for the next 25 years.
