Case Study: a Fortune 500 leader achieves faster app modernization with vFunction

a fortune 500 leader cuts 20-year-old Java monolith modernization cycles to monthly releases with vFunction

The customer, a fortune 500 leader in the construction, mining, energy, and transportation industries, faced significant technical and personnel challenges in modernizing its decades-old Java monoliths. These legacy applications hindered engineering velocity and relied on subject matter experts with undocumented knowledge. To overcome these obstacles, the company's Application Center of Excellence turned to vFunction for an automated solution to decompose architectural complexity.

vFunction provided a data-driven, structured approach to modernization, enabling the team to break down a monolith into a modular Java Spring Boot application. This process accelerated subsequent modernization efforts and instilled greater confidence in the team. As a result, vFunction helped shift the company's release cycle from quarterly to monthly updates, significantly improving agility and reducing risk. The company is now scaling this success by modernizing a revenue-critical application into microservices deployed on Red Hat OpenShift.
