How Mahindra & Mahindra modernized their Dealer Management System to drive efficiency and agility

This article describes how Mahindra & Mahindra modernized their legacy Dealer Management System by migrating from an on-premises monolithic architecture to a cloud-native solution on AWS.

• Legacy system faced performance bottlenecks, scalability constraints, and integration challenges
• M&M chose custom cloud-native solution over COTS products to protect intellectual property
• Architecture uses microservices on Amazon EKS with Aurora PostgreSQL and DocumentDB
• Hybrid connectivity via AWS Direct Connect enables seamless transition between legacy and new systems
• Data migration orchestrated using AWS DMS with change data capture for minimal disruption
• Amazon Cognito unified authentication with Microsoft Entra integration for single sign-on
• Integration layer built with API Gateway, MSK, and AppFlow for external system connectivity
• DevOps pipeline using CodePipeline, CodeBuild, and CodeDeploy enables rapid deployments
• Results: improved performance, faster feature deployment, cost optimization, enhanced security

The modernization enables M&M to handle peak loads seamlessly, reduce feature deployment time from months to days, and support future vehicle launches with improved operational efficiency.
