The Challenge

The bank's monolithic on-premises core banking platform was constraining product velocity, with release cycles measured in quarters and growing concerns about scalability and resilience.

  • 1Monolithic core banking platform with quarterly release cycles limiting product innovation
  • 2Aging hardware approaching end-of-life with rising operational costs and reliability concerns
  • 3Strict central bank regulatory requirements for data residency, audit trails, and BCP

Our Solution

CloudGate designed and delivered a phased modernization to Azure, decomposing the core into containerized microservices on AKS while maintaining a hybrid bridge for sensitive workloads.

  • Hub-and-spoke landing zone with Microsoft Cloud Adoption Framework guardrails
  • Containerized core services on Azure Kubernetes Service with active-active multi-region resilience
  • End-to-end security with Microsoft Sentinel, Defender for Cloud, and Entra ID conditional access
