Real-Time Resilience: Scaling Financial Risk Assessment with Event-Driven Cloud Architectures

Abstract

This paper examines the use of Event-Driven Architecture (EDA) patterns to improve the optimization of financial risk evaluation in a distributed cloud-based system of finance.Today's financial system is characterized by a number of difficulties in processing high-speed data feeds in a timely manner, ensuring sub-millisecond latency and high availability.This paper proposes a decoupled system utilizing distributed event brokers and stream processors to identify market anomalies and credit risks in a timely fashion.This research utilizes a risk data set of 404 unique risk scenarios, including high-frequency trading (HFT) simulation data and credit transaction data, to measure system efficiency.The system environment utilizes Apache Kafka for event streaming, Kubernetes for cloud orchestration, and Prometheus for monitoring.The results show that event-driven architecture can improve system efficiency by eliminating traditional requestresponse processing bottlenecks.Furthermore, by utilizing distributed ledgers and serverless architecture, financial organizations can improve their risk profile granularity.The results show that by utilizing reactive programming, financial organizations can improve their risk management approach by shifting their traditional reactive approach to a proactive approach.
