Traditional monolithic regulatory systems cannot keep up with modern digital banking because of tightly coupled components, long release cycles and high maintenance costs. To overcome these limitations, this paper proposes a microservices-based modernisation framework for financial regulatory systems based on Java Spring Boot microservices, Red Hat OpenShift container orchestration, DevOps automation, and cloud-native governance. The proposed architecture decouples legacy monoliths into independently deployable business services communicating through secure REST APIs, API gateways and asynchronous messaging platforms. The platform enables continuous software delivery with regulatory integrity built directly into CI/CD pipelines, including security scanning, automated compliance checks, Infrastructure-as-Code practices, and policy enforcement. Integrated observability enables end-to-end visibility and audit preparedness with centralised logging, distributed tracing, and real-time operational dashboards. From an architectural perspective, this approach greatly improves system scalability, deployment flexibility, operational robustness and policy adaptability, providing financial institutions with a pragmatic model for cloud-native digital transformation.
