Case Study: a $7B global hotel franchise modernizes its 30-year-old reservation system with vFunction and AWS ModAx

Global Hotel Franchise modernizes 4,000+ hotels’ reservation system with vFunction

A global hotel franchise faced the challenge of modernizing its 30-year-old, heavily entangled property reservation system. The legacy J2EE monolith, acquired in 2019, hindered engineering velocity and prevented the company from scaling on AWS or leveraging modern cloud services. To address this, the company partnered with the AWS ModAx program and utilized vFunction's architectural observability platform to visualize the application and plan its modularization.

Using vFunction, the company developed a data-driven plan to incrementally modernize its system. The solution provided continuous architectural observability and automated alerts for architectural drift, which accelerated feature development and enabled the full use of AWS cloud services. vFunction helped ensure the modernization was successful, preventing future technical debt and the need for another large-scale project.
