Modernize and migrate your monoliths with vFunction

Years of feature creep, patchwork development, and neglecting architectural considerations, lead to bloated and sluggish apps. vFunction’s AI-driven architectural observability platform gives you visibility across your application portfolio, helping to quickly understand and transform your legacy systems into modular, cloud-ready apps.

Bring your legacy apps into a cloud-ready world

Maintaining legacy apps can feel like playing Russian roulette — lifting and shifting to the cloud adds to the stress. vFunction’s AI-driven platform gives you deep visibility into your architecture, identifying domains, uncovering dependencies, and pinpointing sources of technical debt. It guides you through modularizing your app and automates microservices extraction, API creation, and framework upgrades. vFunction is the only platform that models apps in real time to de-risk and accelerate your modernization journey.

Identify specific refactoring opportunities

The root cause of many software issues lies in the underlying architecture. vFunction identifies architectural issues and pinpoints where, how, and why to address them. Examples of architectural issues are below.

Domain exclusivity issues

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.

Resource exclusivity issues

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. Architects should assess whether this broader distribution is intentional or a sign of architectural issues.

Dead code

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.

One platform for static and dynamic code analysis

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.

Reliable support for Java and .NET applications

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.

Are your apps cloud ready?

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.

Moving from monoliths to microservices

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.

Start operating at cloud scale

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.
