The Challenge

Cloud migration of bank applications

They wanted to migrate critical front-office Investment Banking (IB) applications to the Azure Cloud.


The Objective

Technology standardization and scalability

  • Expedite the bank’s cloud adoption strategy
  • Achieve technology standardization aligned with the client’s futuristic vision with the removal of legacy technology
  • Realize scalability through cloud acceleration team, migration PODs across IB portfolio and larger bank’s ecosystem
  • Consolidation, standardization and automation by containerization, integration with Enterprise Vault solution and heterogeneous database migration from Oracle 11g DBaaS to PostgreSQL
  • Accomplish near-term and long-term cost savings coupled with effective visibility and control of costs

The Solution

Platform upgrade and database migration

  • Upgrade to the latest Camel and Spring versions and migrate from RHEL 6.x, 7.x to AKS Linux Container
  • Leverage PaaS services, such as AKS, Azure Key Vault, Azure Storage, Azure Monitor and Azure Log analytics
  • Implement Azure AD for multi-factor authentication and secure identity management
  • Migrate from Oracle 11g DBaaS to Azure-managed PostgreSQL
  • Set up DevSecOps CI/CD pipelines for faster and more secure deployments using Azure DevOps and GitLab CI and enhancing the process of customers deploying applications

The Impact

Better management of operational overheads and security

  • PaaS-first approach resulted in managing operational overheads better by containerization of applications to AKS, leveraging Azure DevOps
  • Established security best practices by securely storing and managing sensitive information, such as keys, passwords and certificates across on-premises and cloud via HashiCorp Vault and Azure Key Vault
