How Ksolves Modernized a Monolithic Banking Application to Microservices on OpenShift
Our client is a prominent multinational bank with a presence across Europe and Asia, serving millions of retail and corporate customers. Their legacy banking platform, developed over 15 years, was monolithic and tightly coupled, making it difficult to introduce new features, scale during high-demand periods, or maintain efficiently. With digital banking becoming increasingly competitive, the client sought a modern, cloud-native solution that could improve agility, support rapid innovation, and handle growing transaction volumes while maintaining strict regulatory compliance.
The bank’s legacy monolithic system had served them well for years, but it came with significant limitations that hindered growth and innovation:
- Slow Feature Delivery: Every new feature required changes across multiple interdependent modules, making release cycles long and error-prone.
- Limited Scalability: During peak transaction periods, the system struggled to handle the load, and scaling vertically was expensive and inefficient.
- High Maintenance Overhead: Debugging and updating the monolithic codebase were time-consuming and complex. This slowed down development and increased operational costs.
- Inflexibility for Innovation: The tightly coupled architecture made it difficult to experiment with new fintech features or integrate third-party services.
- Security and Compliance Risks: Being a highly regulated financial institution, the bank needed a solution that maintained strict data security, auditability, and compliance during and after modernization.
- Operational Downtime Risks: Deployments or updates often led to system downtime, impacting customer experience and transactional reliability.
To address the bank’s challenges, Ksolves implemented a comprehensive modernization strategy leveraging OpenShift, transforming their monolithic system into a flexible microservices architecture.
- Breaking Down the Monolith: We analyzed the legacy banking system and identified independent modules such as account management, payments, KYC verification, and loan processing. Our experts refactored each module into a containerized microservice so that it can be deployed, scaled, and maintained independently.
- OpenShift as the Core Platform: We containerized all microservices using Docker and deployed them on Red Hat OpenShift Container Platform. Kubernetes orchestration enabled automatic scaling, load balancing, and high availability. This ensured seamless performance even during peak loads.
- CI/CD Automation: We implemented GitLab CI and OpenShift pipelines to automate build, test, and deployment processes. Further, we introduced blue-green and canary deployments to minimize downtime and reduce release risks.
- Enhanced Security & Compliance: Our experts configured Role-Based Access Control (RBAC), Network Policies, and Secrets Management to secure service-to-service communication. They ensured full compliance with banking regulations and maintained audit trails and data privacy during the migration.
- Monitoring and Observability: We introduced Prometheus and Grafana for real-time metrics, monitoring system health, and autoscaling decisions. Plus, we integrated ELK Stack (Elasticsearch, Logstash, Kibana) for centralized logging, proactive troubleshooting, and operational insights.
- Seamless Transition with Minimal Disruption: Finally, our experts migrated services incrementally and ensured that daily banking operations continued uninterrupted.
- Training and Documentation: We provided training and documentation for internal teams to manage and operate the new OpenShift environment efficiently.
- 3x Peak Load Handling: OpenShift’s autoscaling and load balancing enabled the system to manage 3 times the usual transaction volume seamlessly.
- Release Cycles from Weeks to Days: Release cycles were reduced from weeks to days, allowing the bank to launch new products and services faster.
- 25% Cost Reduction: Containerization and microservices cut infrastructure and operational costs by 25%, increasing overall efficiency.
- 100% Compliance & Security: RBAC, network policies, and secrets management ensured full regulatory compliance while safeguarding sensitive banking data.
- Minimal Manual Intervention: Automated CI/CD pipelines and proactive monitoring drastically reduced human errors and operational downtime.
With Ksolves’ expertise in OpenShift consulting and cloud-native modernization, the bank successfully transformed its monolithic system into a flexible, microservices-based platform. Our team’s experience in refactoring complex legacy systems, implementing automated CI/CD pipelines, and ensuring regulatory compliance made the modernization process smooth and risk-free. The result is a platform that deploys faster, scales seamlessly, and operates efficiently, enabling teams to innovate independently and respond to customer needs more effectively.
