The Challenge

Modernize and Transform: Collaboratively partner with the CNAN team to re-architect and redesign several tightly integrated legacy application systems. These systems, some of which have utilized technologies and designs spanning over three decades, require modernization to align with CNAN's ambitious long-term business and technology goals.

This modern architecture allows CNAN to utilize SaaS and PaaS solutions for both vendor and in-house services, enabling the agility required to quickly introduce new customer products and services at scale. This fully integrated architecture transparently incorporates operational and analytical data services, facilitating real-time decision-making and enhancing operational efficiency.

Mitigate Negative Impacts: Minimize disruptions to CNAN's day-to-day business operations throughout the implementation of modernization initiatives.

Early Benefits and Stakeholder Support: Achieve early benefits to secure support for business process changes and adaptations, as well as to validate the architecture and designs.

Innovations and Cost Reduction: Identify frameworks, enhancements, and innovative technologies to streamline processes and reduce overall complexity and costs, all while prioritizing flexibility and adaptability to change.

Proactive Data-Driven Decision Making: Collaborate with both the business and IT teams to craft a solution architecture that supports the organization's shift towards proactive and agile data-driven decision-making.

Accelerate Time to Market: Implement solutions aimed at significantly reducing time to market for new products and services, while also maximizing value for CNAN customers.

Enhance Product Performance Tracking: Integrate data and services to enhance product analytic capabilities, providing benefits to both dealers and underwriters.

Solution Highlights

Roadmap featuring iterative milestones, avoiding a "big bang" approach.
Establishment of a bridge between legacy and modern technologies.
Deployment of new or replacement components on the Cloud, seamlessly integrated with existing on-premise legacy systems.

Highlights of the solution are:

Rule based middleware to dynamically transform data from the new (modernized replacement) system to legacy systems requiring that data.
This “Bridging Strategy” is an essential innovation to permit new applications to be released incrementally and allow legacy systems and their dependencies to continue until they can be safely decommissioned.
Use of in-memory database for a new rating engine with significantly improved scalability, robustness, and performance characteristics.
Integrated data architecture which underpins all operational and analytical services.

Technologies Used

Ready to Modernize?

Modern IT systems aren’t just about compliance — they’re about enabling agility, scalability, and cost efficiency. They’re also about making the right judgment calls: preserving and evolving what makes your business unique, while integrating or
standardizing what is simply a table-stake capability.

Every year, code maintenance costs average 25% of the original build. The opportunity cost of not modernizing is even higher. The real challenge is making architectural decisions that avoid over-engineering or platform lock-in — and ensure systems remain sustainable.
