Case Study: Correla modernises Gemini with vFunction

Correla analyses 10M lines of Gemini code in 10 days with vFunction

Correla, one of the largest UK-based providers to the energy market, faced the challenge of modernizing its critical Gemini application, a complex monolith of over ten million lines of Java code. This complexity led to long release cycles and slow engineering velocity. Partnering with vFunction, Correla needed to accelerate and de-risk this modernization with a zero-tolerance for downtime.

Using its AI-driven platform, vFunction provided a full analysis of the 10-million-line application in just over 10 days, identifying optimal microservice boundaries. The solution automated the extraction of the first microservice, which was successfully deployed to Azure. For Correla, vFunction’s involvement significantly reduced time and risk, paving the way for an iterative, risk-free modernization of the entire application.
