A leading Australian telecommunications provider initiated a strategic modernization program to migrate its critical order management platform from an on premises, monolithic COTS solution to AWS. The legacy system had been in operation for over a decade and was central to business fulfillment processes. Over time, aging infrastructure, manual operations, and limited scalability made the platform increasingly complex and costly to maintain.
To address these challenges and support future growth, the client partnered with Infosys to modernize the platform using AWS cloud native capabilities. Infosys led the migration of the order management fulfillment suite to AWS, transforming it into a scalable, highly available, and secure solution. The modernization enabled self managed operations, improved resilience, and eliminated downtime during application patching.
By adopting containerized deployments, automated scaling, and cloud managed databases, the client significantly improved operational efficiency and system reliability. The transformed platform now supports elastic scalability, faster releases, and near zero deployment downtime—providing a future ready foundation to support evolving customer programs and increasing order volumes.

The Solution
Future ready transformation migrating decade old order systems to AWS for agility and resilience
Infosys partnered with the client to modernize its order management fulfillment suite through a structured migration to AWS. A comprehensive transition plan ensured smooth knowledge transfer from the incumbent vendor while minimizing operational risk. Applications were deployed across multiple nodes, enabling high availability and allowing patching to be performed node by node without downtime.
Databases were migrated from Oracle to Amazon Aurora PostgreSQL, improving scalability, resilience, and performance. A routing based load balancer strategy minimized IP usage while enhancing traffic management. External integrations were securely exposed using Amazon Route 53.
Security was further strengthened by replacing the existing Azure AD based SSO with Keycloak integration across applications. Business logic and workflows were centralized within the database layer, improving security compared to the legacy file based approach. Comprehensive system, integration, and user acceptance testing validated performance improvements and ensured production readiness.
