vFunction Introduces GenAI-Powered Architectural Intelligence for Code Assistants
Faster modernization starts with architecture
Modernization isn’t just about upgrading code or containerizing workloads. To realize meaningful cost savings, elasticity, and speed, you need to modernize the architecture.
vFunction combines GenAI and data science to analyze and modularize Java and .NET monoliths, guide code assistants in refactoring, and extract cloud-ready microservices — modernizing apps up to 15x faster than traditional methods.
“I wish we had vFunction when I started at Turo. This kind of architectural observability gives us a much better understanding into our application and helps us with decision making as we move forward."

Senior Engineering Manager at Turo
Modernize & manage apps from one platform
Once monoliths are broken into modular services, vFunction provides ongoing oversight across distributed applications.
By leveraging OpenTelemetry to support a wide range of languages and stacks, we deliver deep architectural insight to prevent sprawl, enforce boundaries, and monitor drift, keeping your systems scalable and resilient over time.
Maximize your cloud investments
vFunction partners with AWS, Microsoft Azure, and other leading hyperscalers to modernize applications for advanced cloud services.
AWS
vFunction partners with AWS across a range of programs to accelerate and de-risk modernization initiatives—enabling qualified customers to access fully funded licenses and expert support.
Microsoft Azure
vFunction collaborates with Microsoft Azure to help growing companies and global brands modernize complex, business-critical applications. Available on Azure Marketplace, vFunction aligns legacy transformation with your cloud strategy.
Use Cases
Real world modernization
From high-stakes financial services to high-tech applications and heavily industrialized manufacturing environments, vFunction helps engineering teams around the world modernize faster and with less risk.
Cloud migration
vFunction breaks down massive, mission-critical monoliths and rebuilds them for cloud-native scale and agility.
Architecture-aware prompts help code assitants refactor class dependencies, untangle circular flows, and improve domain boundaries.
The result? Modular, scalable, lower cost, maintainable applications—and faster modernization at scale.
Beyond lift and shift
Rehosted your applications to VMs or containers but not seeing cloud benefits?
vFunction transforms stalled migrations into success stories.
Leverage the full power of vFunction to modernize your architecture and accelerate your path to advanced cloud services.
Realize the scalability, elasticity, and cost savings the cloud was meant to deliver.
Manage & improve
Modernization doesn’t end after refactoring, it’s an ongoing process.
With vFunction, you can manage and improve your evolving architecture to monitor architectural drift and prevent microservices sprawl.
Stay ahead of technical debt and continously maintain scalable, resilient systems, release after release.
From monolith to microservices
Engineering teams and architects use vFunction to observe their application architectures, transform them into modular domains, and extract them into deployment-ready microservices.
