Business Opportunity

Application Migration From On-Prem to GCP

HDFC ERGO General Insurance Company, a collaboration between HDFC—India’s leading housing finance institution—and ERGO International AG, the primary insurance arm of the Munich Re Group, offers a comprehensive suite of general insurance products, including motor, health, travel, home, and personal accident insurance for retail customers. 

To expand its customer base and embrace modernization, HDFC ERGO set out to transition its applications to cloud infrastructure. This shift aimed to move the application layer from on-premises to the cloud, paving the way for the organization to evolve as a leader in AI-driven innovation and digital transformation.

Niveus Solutions, part of NTT DATA, helped HDFC ERGO in their modernization journey by efficiently migrating the application layer from on-premises to Google Cloud Platform (GCP), enabling the organization to establish itself as a leader in AI innovation and digital transformation.

The Challenge

Legacy System Complexity: Migrating the complex application layers from legacy systems required overcoming compatibility issues and re-engineering tightly integrated systems without disrupting operations.

Data Migration and Security: Transferring large volumes of sensitive customer and transaction data necessitated stringent data security measures, including encryption and compliance with privacy regulations.

Downtime and Business Continuity: Ensuring minimal downtime during the migration process was critical to maintaining uninterrupted customer experiences and business operations.

Our Solution

Niveus played a key role in HDFC ERGO’s modernization efforts by migrating their application layer from on-premises to Google Cloud Platform (GCP), helping them transition into an AI and Digital-First organization.  

To enhance scalability and improve customer engagement, HDFC ERGO upgraded its application infrastructure by adopting a cloud-based architecture. The migration was carefully planned to maintain business continuity, with the on-premises systems running alongside the cloud setup.  

The solution leveraged Apigee External Load Balancer to route client requests, with Cloud Armor providing protection against DDoS attacks and acting as a Web Application Firewall (WAF). The application layer was deployed on Google Compute Engine’s Unmanaged Instance Groups, enabling a robust backend service.  

Databases remained on-premises, connected to the GCP application through Partner Interconnect. Requests were managed via an Apigee load balancer, which directed traffic to the application tier hosted behind an internal load balancer. This tier seamlessly connected to the on-premises databases, ensuring a smooth and secure operation throughout the migration process.

Enhanced resilience
