  • Abstract

    As digital banking demands round-the-clock availability of critical functions such as payment processing and account management, traditional centralized data centers and manual backup techniques are no longer satisfying the rigorous uptime and recovery requirements. To address these limitations, in this paper we present a high availability (HA) and disaster recovery (DR) architectural framework designed for containerized banking workloads. This framework is based on an active-active deployment model across geographically distributed data centers and combines container orchestration with intelligent traffic routing, automated load balancing, storage failover, dynamic database synchronization and automated recovery workflows. The study evaluates important resilience metrics, including Recovery Time Objective (RTO), Recovery Point Objective (RPO), failover efficiency, and system availability, and demonstrates the superiority of containerized active-active architectures over traditional recovery techniques. This paradigm ultimately provides a scalable blueprint for financial institutions to achieve continuous service availability, rapid fault recovery, strong data governance and regulatory compliance during infrastructure outages.
