Context
In a highly regulated banking environment, collateral and Initial Margin management are critical for risk monitoring and compliance with financial market requirements. In this context, a leading investment bank launched the modernization of its application dedicated to monitoring and calculating initial margins, used by teams in charge of collateral activities. This initiative aims to support the transformation of the information system by progressively migrating the application to a new Cloud-based technological platform (MPT) hosted on Microsoft Azure, while ensuring operational continuity and the reliability of financial calculations. To support this transformation, Avaliance worked within the Collateral teams to maintain the existing solution and support the transition toward the new Cloud architecture.
Challenges
The client needed to modernize a critical application while ensuring continuity of processes related to collateral margin monitoring and Initial Margin calculations.
One of the main challenges was maintaining the legacy application in operational condition while preparing its evolution toward a more modern and scalable Cloud platform.
