Transforming Investment Operations with Rocket® Visual COBOL®

FIS

FIS, a global leader in financial technology, sought to enhance the performance and scalability of its InvestOne platform while preserving core business logic and ensuring operational continuity. Here’s how Rocket® Visual COBOL® helped to achieve it.

Challenge

FIS relied on a mainframe-based architecture that limited scalability and struggled with increasing workloads. Modernizing InvestOne required improving performance and flexibility, without risking business continuity.

Solution

Using Rocket Visual COBOL as a foundation, FIS replatformed InvestOne to Linux®, enabled COBOL-to-Java integration, and supported a containerized, cloud-compatible architecture to scale and support modern frameworks.

Results

The transformation delivered over 20% faster performance, enabled continuous monthly updates, and introduced flexible deployment across mainframe and cloud environments, ensuring long-term scalability and efficiency.

When we rolled out the replatformed application, we saw an overall performance boost of more than 20 percent. Not only are our processes running faster, but we can scale out and run more concurrent processes.
