Please reference the vFunction Quick Start Guide for detailed installation instructions. vFunction is a cloud-native modernization platform that combines dynamic and static code analysis, data science, and automation to automatically identify and extract services from existing applications. vFunction is the only platform purpose-built for modernization of Java applications.

The vFunction modernization process starts by dynamically analyzing the running monolithic application and surfacing interdependencies. Using data science, graph theory and clustering algorithms, the platform analyzes and identifies services that can be separated from the application. This decomposition can present a range of micro, mini, or even macro services, depending on your application environment, each being an independently deployable and scalable application component. vFunction automates the extraction of these services, enabling you to modernize your monolith, quickly and easily.

The platform consists of 3 basic components; the server, the controller package, and a tools package. The server runs on a Linux machine, with Docker installed. The controller package is installed on the machine that runs the monolithic application which can be either a Linux or a Windows machine, and the tools are run on a development machine, with access to the code of the monolithic application.

The controller package consists of three elements: the vFunction agent, that collects data during the dynamic analysis phase; the vFunction Viper application, that performs static analysis on the binaries of the application; and the vFunction controller that handles all the communication between the agent, Viper, and the vFunction server.

The vFunction agent is a mix of a Java and native agent, and needs to run on the JVM that is currently running your application. Refer to the vFunction Support Matrix document for a list of supported application servers and JVMs.
