A multinational oil and gas company initiated a strategic modernization program to transform its legacy Market Value at Risk (MVaR) monolithic system into a modern, cloud native application landscape. The existing system, built on aging Java and ASP.NET technologies, suffered from high technical debt, performance bottlenecks, and long release cycles—limiting operational efficiency and responsiveness to business needs.
Infosys partnered with the client to drive digital transformation through cloud adoption, with the goal of delivering a simplified, scalable, and intuitive self service platform. The modernization focused on re architecting the legacy monolith into a microservices based .NET cloud native architecture, containerized and deployed on Amazon Web Services (AWS). By leveraging Amazon ECS and modern DevOps practices, the new platform improved agility, scalability, and automation across the application lifecycle.
The transformed solution delivered significant improvements in runtime performance, operational efficiency, and time to market, while strengthening security and observability. The initiative enabled the client to transition from a tightly coupled legacy system to a resilient, future ready digital platform—aligned with business goals and capable of supporting evolving risk management and analytics needs.

The Solution
Cloud native modernization delivering a scalable, secure, and user driven enterprise application
Infosys modernized the client’s legacy MVaR system into a cloud native, microservices based .NET application on AWS. The solution was architected to improve scalability, resilience, and development velocity while simplifying operations.
Independent service layers enabled modular deployment and faster change cycles. Containerization and automated deployments reduced infrastructure complexity and improved environment consistency. Application Load Balancers ensured high availability and efficient traffic distribution across services.
Enterprise grade security was strengthened through integration with Azure Active Directory for single sign on, while centralized logging and monitoring provided real time visibility into application health and performance. The modernized platform delivers an intuitive, self service experience for users and supports advanced reporting, what if analysis, and scenario based decision making—creating a future ready foundation for digital risk management.
