Modernizing at Scale: A Fortune 500's Approach to Application Transformation
Read Case StudyMigration and Modernization
Most AWS migrations stall because applications are too complex
Lift-and-shift gets apps to EC2, but not to Amazon EKS, ECS, or Lambda. vFunction powers Kiro to refactor and rearchitect Java and .NET monoliths into container-ready microservices.

How it Works
A new way to modernize applications
Instead of manual rewrites and expensive service engagements, vFunction powers Kiro to reliably refactor complex Java and .NET applications, something code assistants lack the context to do on their own. This makes modernization faster, more predictable, and cost-effective.
Modernization Patterns
Solve the toughest migration and modernization challenges
60% of applications never complete their migration
Even after 18-24 months, most applications stall, either on-premises or after lift-and-shift to EC2. Complex, tightly coupled architectures limit progress toward containers and managed services.
This guide shows how AWS teams move beyond EC2 using vFunction to refactor and rearchitect applications for EKS, ECS, and Lambda.
Execute a clear, low-risk plan to move stalled applications into scalable, cloud-native services.
Eliminate Windows licensing. Move .NET off EC2.
Many .NET applications on AWS remain stuck on Windows-based EC2. Tightly coupled architectures and framework dependencies limit progress, driving ongoing licensing costs.
This guide shows how AWS teams use vFunction to modularize complex .NET applications and move to Linux, containers, and managed services like EKS, ECS, and Lambda.
See how to capture the cost and performance benefits of Linux and containers on AWS, and leverage AWS funding programs to accelerate the move away from Windows.
Can Kiro reliably refactor an 8M LoC application?
Code assistants like Kiro can generate and modify code, but they lack the architectural context to reliably refactor complex brownfield applications.
vFunction combines runtime data, binary analysis, and data science to provide the context needed to refactor applications, complemented by user input through its interactive architectural studio.
This comprehensive approach enables vFunction to generate a precise modernization plan, powering code assistants and ensuring consistent, deterministic results.
Case Studies
Modernizing applications on AWS today
Six real-world stories of how teams are moving off Windows, adopting containers, and using AI to scale services on AWS.
Modernizing a platform supporting millions of vehicles
The software company behind Europe’s most respected automotive brands is modernizing its platform and migrating to Amazon EKS to support the next generation of connected vehicles.
Removing Windows licensing. Modernizing a .NET platform.
By moving from Windows-based EC2 to Linux-based, containerized services on Amazon EKS, this HR tech company reduced costs by 40%—eliminating licensing costs and improving efficiency.
Refactoring a mission-critical app with agents and architecture
Learn how vFunction helped a global consumer goods manufacturer use Kiro and nine AI agents to transition services to Amazon ECS and AWS Lambda.
Evolving an insurtech platform for growth
Previous modernization efforts stalled due to tightly coupled architecture. With vFunction and Kiro, this global insurtech provider gained the clarity to safely refactor a mission-critical platform and support future growth.
From analysis paralysis to cloud-native performance
After a lift-and-shift to EC2, CDL didn’t see the expected gains. With vFunction and Amazon Q, they modularized their Policy Administration System and moved toward cloud-native performance.
Modernizing a complex security platform
Learn how Trend Micro used vFunction to refactor a complex monolithic security platform, accelerating deployment speed by 12x and enabling faster cloud-native execution.
AWS Programs
Accelerate modernization with AWS funding and programs
With AWS ISV Tooling and EBAs, teams can move beyond EC2 faster.
Fully funded access to vFunction
AWS covers vFunction licensing through the ISV Tooling Program, removing budget barriers and enabling teams to start modernization immediately.
- No upfront cost — licensing fully funded by AWS
- Designed for applications blocking progress to managed services
- Focus on real outcomes. Not just assessments. Plans and execution.
From architecture to execution
AWS Experience-Based Accelerations (EBAs) provide a structured, low-risk path from architecture discovery to AI-based refactoring and modernization.
- AI Modernization Showcase: Define the architecture, identify service boundaries, and try AI-driven refactoring.
- Refactor and extract high-priority services with vFunction, Kiro, and AWS Transform
