vFunction transforms complex applications into cloud-native, AI-ready systems with runtime architectural context for code assistants.
Overview
vFunction is an AI-augmented code modernization tool focused on architectural transformation of complex applications into cloud-native services. It powers code assistants (like Amazon Kiro) with runtime architectural insights, transforms Java and .NET monoliths into modular, microservices-based, AI-ready, apps, at least 15X faster than traditional efforts, while automating fixes and eliminating architectural technical debt.
Use Cases
Modernize to the Cloud
Complex on-premises monoliths accumulate years of architectural technical debt, making it difficult to release quickly, scale efficiently, or adopt AI. Lift-and-shift migrations rarely succeed: costs rise, elasticity is limited, and architectural debt follows applications into the cloud extensive rework, costs skyrocket on oversized machines, and architectural debt blocks elasticity and savings.
With vFunction and GenAI, teams refactor as they migrate, addressing debt head-on and enabling cloud benefits at a fraction of the time, cost, and risk.
Move to Higher Compute Services
In some cases, urgent migrations-such as data center shutdowns force enterprises to move applications quickly to higher compute services without the chance to modernize. While this ensures continuity, delaying modernization leads to ballooning expenses, lost elasticity, and reduced engineering velocity.
By applying vFunction and GenAI, organizations can modernize rapidly after migration, reducing costs and risks while unlocking the full power of cloud-native platforms like Amazon EKS, AWS Fargate and AWS Lambda.
Highlights
- vFunction combines patented static and dynamic analysis methods to automatically identify flows, domain boundaries, dependencies and uncover technical debt. It is the only platform that brings domain-driven design context to GenAI code assistants like Kiro for faster, more precise refactoring.
- vFunction is a part of the AWS ISV tooling program and fully funded by AWS for qualified customers and system integrators. Reach out to us for more details: alliances@vfunction.com

Pricing
Pricing is based on the duration and terms of your contract with the vendor. This entitles you to a specified quantity of use for the contract duration. If you choose not to renew or replace your contract before it ends, access to these entitlements will expire.
Additional AWS infrastructure costs may apply. Use the AWS Pricing Calculator to estimate your infrastructure costs.
Dimension | Description | Cost/12 months |
|---|---|---|
S - 2000 | 1 Java or .NET Application, Upto 2,000 Classes | $28,000.00 |
M - 5000 | 1 Java or .NET Application, Upto 5,000 Classes | $48,000.00 |

Dimensions summary
Pricing follows a t-shirt sizing model based on how many classes your application contains. You license one Java or .NET application per contract. The sizes range from S at up to 2,000 classes, through M, ML, L, XL, 2XL, and 3XL at up to 100,000 classes. Each larger size covers a higher class count. If your application exceeds 100,000 classes, or you need to cover multiple applications, you contact vFunction for custom terms. You pick the size that matches your application's scale.
Top-of-mind questions for buyers
Each Java Virtual Machine or common language runtime counts as one application. Similar code bases count once. Microservices are not counted as separate applications. Your size tier is set by the number of classes in that one application, so you pick the tier that covers your class count.
No. The platform sets no limit on users. Architects and developers can all use its insights, recommendations, and automation. Pricing depends only on the application and its class count, not on how many people access the tool.
The >100000 tier covers Java or .NET applications with a custom class count. You contact vFunction to arrange terms. For multiple applications, the fair-use policy limits total JVMs or CLRs to no more than ten per business application. Contact vFunction for multi-application coverage.

Amazon Machine Image (AMI)
An AMI is a virtual image that provides the information required to launch an instance. Amazon EC2 (Elastic Compute Cloud) instances are virtual servers on which you can run your applications and workloads, offering varying combinations of CPU, memory, storage, and networking resources. You can launch as many instances from as many different AMIs as you need.
