Download NowBloated, brittle applications result from years of patchwork fixes that are hard to untangle. vFunction accelerates architectural modernization by combining architectural observability, data science and GenAI to uncover technical debt, guide LLM code assistants, and automate remediation—enabling self-healing architecture that improves quality, boosts velocity, and ensures your applications are cloud-ready.
Modernizing without architectural insight leads to risk, rework, and cost overruns.
vFunction identifies modular boundaries, surfaces technical debt, and guides GenAI assistants with architecture-aware prompts. By automating service extraction, API creation, and framework upgrades, it makes modernization repeatable and scalable. Think of it as the navigation system for your code assistants—bringing clarity and control to your cloud journey.
Architectural issues are the source of many software problems. vFunction pinpoints where, how, and why to address them—generating optimized prompts to guide code assistants in resolving them. Below are examples of issues vFunction helps remediate.
vFunction identifies and analyzes your application and can determine logical domains and their boundaries — something that takes weeks or months in a manual event-storming exercise. It then calculates the degree to which these domains are modular and pinpoints the specific class dependencies to modularize the application.
Multiple domains relying on the same resources signals increased complexity. vFunction identifies and analyzes exclusivity of different resources, such as database tables, files and more and then generates prompts to fix those dependencies using code assistants.
vFunction identifies dead flows and obsolete code. While static analysis tools are able to identify unreachable code only, dynamic analysis in the context of domains, can identify code that is practically dead within a domain, since it never meets the logical conditions to run. Regularly reviewing and cleaning up your codebase maintains efficiency and ensures long-term maintainability.
vFunction combines patented static and dynamic analysis methods to automatically identify flows, domain boundaries, dependencies and uncover technical debt. It’s the only platform focused on efficiently modernizing legacy apps by analyzing binaries statically with dynamic runtime analysis, so no potential issue goes undetected.
For your application modernization projects, vFunction supports legacy applications built with popular programming languages Java and .NET. We also accommodate a wide range of application servers, including Oracle WebLogic, IBM WebSphere, Tomcat, Red Hat JBoss, and many others, along with various JVMs and JDKs.
As a cloud-agnostic platform, vFunction offers tailored architecture and code guidance for your target environment during cloud migrations, helping teams extract domains and optimize applications for the cloud.
vFunction helps you isolate and modularize domains within your monolithic applications, accelerating microservices creation. With vFunction Code Copy, you can automate code extraction, generate RESTful APIs for your services, and seamlessly handle necessary domain specific framework upgrades leveraging vFunction’s integrated OpenRewrite recipes.
vFunction collaborates with leading providers to modernize applications and facilitate efficient cloud migration. Leverage vFunction's architectural observability platform to modularize applications, transform monoliths into microservices, and upgrade legacy software to harness the full potential of advanced cloud services.
