Case Study
Disaster Recovery for Bank Using AWS DRS, EBS and Scalable Cloud Storage
Executive Summary
Saints & Masters partnered with the client to modernize its disaster recovery strategy for critical banking systems. With increasing volumes of sensitive financial data and the need for high availability, the bank required a reliable, secure, and scalable solution to ensure business continuity. By leveraging AWS Elastic Disaster Recovery and related cloud services, a robust real-time replication and recovery architecture was implemented, significantly reducing downtime, minimizing data loss, and optimizing infrastructure costs.
- Industry: Banking & Financial Services
- Geography: India
- Capability: Hyperscaler Orchestration
- Technologies: Amazon DRS, Amazon Storage
- Key Outcome: Our solution at Saints & Masters significantly strengthened the client's disaster recovery posture by enabling near real-time data replication and highly reliable failover capabilities. The implementation achieved a major improvement in resilience, reducing the RPO from approximately 4 hours to less than 5 minutes, ensuring minimal data loss during disruptions. At the same time, the RTO was reduced to under 1 hour, enabling rapid recovery of critical banking services and minimizing operational downtime.
The Challenge
The client operates core banking systems and financial applications from their on-premises data center. These systems handle large volumes of transactional and sensitive customer data, requiring highly durable, secure, and recoverable storage.
Key requirements:
· A secure, durable storage solution that met financial compliance
· RPO < 5 minutes and RTO < 1 hour during outages
· Continuous replication of storage volumes
Delivery
Saints & Masters implemented a cloud-based disaster recovery solution using AWS Elastic Disaster Recovery, enabling secure, continuous real-time data replication and rapid recovery of critical banking systems with minimal downtime and data loss.
Key Features
· Continuous data replication with minimal data loss
· Secure and compliant architecture with encryption and access controls
Results
Our solution at Saints & Masters significantly strengthened the client's disaster recovery posture by enabling near real-time data replication and highly reliable failover capabilities. The implementation achieved a major improvement in resilience, reducing the RPO from approximately 4 hours to less than 5 minutes, ensuring minimal data loss during disruptions. At the same time, the RTO was reduced to under 1 hour, enabling rapid recovery of critical banking services and minimizing operational downtime.
Additionally, our solution improved overall data durability and security through AWS-managed encryption and IAM-based access controls, while also reducing dependency on costly on-premises disaster recovery infrastructure.
