Client is a leading natural resources company that carries out the exploration, development, production, and processing of mineral resources. As part of digital transformation, the client wanted to migrate their on-prem apps to scalable architecture in Azure cloud with aim to maximize the use of public cloud.
Infosys assisted the client in migrating an enterprise application of a mining scheduling system to Azure cloud. We completely rearchitected the existing solution, transitioning from a virtual machine-based application to a modern, containerized architecture. This involved migrating workloads to Azure Kubernetes Service (AKS), enabling better scalability, automation, and resilience
Key Challenges
- High operational costs in managing traditional physical data centers
- High technical debt due to legacy applications
- Longer time taken for application development lifecycles
- Low application stability and uptime

The Solution
Adopting microservices architecture helped client in faster deployment with enhanced flexibility and reduced development and testing cost
This application is a multi-tier software system that comprises of multiple components, including web, API, database, printing, notification, and queuing services. Each component has undergone significant modernization and rearchitecting to leverage cloud-native technologies.
- Modernization and Deployment: The application has been containerized and deployed on Azure Kubernetes Service (AKS), deployed with an in-cluster ingress controller based on NGINX for efficient routing.
- Authentication: Application is uplifted to support Microsoft Entra for user authentication.
- Database Re-platformed: Databases have been migrated to Azure SQL and SQL Managed Instance (SQL MI) to support linked server functionality.
- Printing Service: The printing service has been containerized with Azure File Share used for storing PDF files.
- SignalR Transition: The application now uses Azure SignalR (PaaS) for notification service, eliminating the need for RabbitMQ.
- Secrets Management and Security: Sensitive data is securely stored in Azure Key Vault, and managed identities are used for secure SQL database connections.
- Logging Enhancements: Application logging is managed through Azure Application Insights and Container Insights.
Microservice Design Framework – Optimized resource utilization, accelerated development lifecycle, and simplified cloud adoption
As a trusted strategic partner for modernization, Infosys helped in:
- Streamlining end-to-end migration process using scaled agile delivery principles and continuously adapt to the ever-changing environment.
- Adopting microservices architecture. De-coupled the application and containerized with code uplift.
- Completely rearchitected the existing solution. Moved from VM based application to Azure Kubernetes Service (AKS).
- De-coupling the application and containerized with code uplift. Designed the solution to scale-out and scale-in on demand basis.
- Migrating the database from SQL Server to Azure SQL database and SQL MI.
- Monitoring, dashboards, Webex notifications setup.
