A Fortune 500 U.S. insurer relied on a 30+ year-old mainframe for retirement product enrollment and participant onboarding. Rising platform costs, complex dependencies, and slow-release cycles made innovation and regulatory changes increasingly expensive, while limiting digital participant experiences. LTM worked with business and IT teams to define the target state, then led the architecture, application re-engineering, and data migration. The resulting AWS cloud-native platform reduced OpEx by 90%, lowered TCO by 40–50%, improved availability and processing speed, and enabled more scalable, mobile-enabled retirement experiences.
LTM helped the insurer replace a costly, tightly coupled mainframe with a cloud-native retirement platform. The transformation applied Cloud modernization for insurance principles across applications, data, and delivery practices. This created a more responsive foundation for product innovation, regulatory change, and digital participant experiences.
The client is a Fortune 500 U.S. insurance leader offering retirement products and services. Its legacy platform supported critical retirement product enrollment and participant onboarding for payroll processing. Business and IT leaders faced high platform costs, lengthy release cycles, and increasing complexity. These constraints made innovation and regulatory change more expensive while limiting the insurer’s ability to deliver modern digital experiences to participants.
The retirement platform had accumulated more than three decades of technical debt across multiple mainframes and legacy technologies. This created challenges for both business and IT leadership:
The insurer needed to modernize without disrupting critical retirement operations or compromising data integrity, security, and compliance. This made AWS mainframe modernization a critical part of the transformation strategy.
LTM worked with the insurer’s business and IT teams to define the target state, then led the architecture, application re-engineering, and data migration. The client reviewed and approved the designs and transformed components throughout the program. The transformation replaced tightly coupled legacy components with a cloud-native AWS architecture built for scalability, resilience, and faster change. It also provided a structured approach to AWS mainframe modernization, allowing the insurer to modernize core workloads while maintaining operational continuity.
Together, these changes shifted the platform from a costly legacy dependency to a flexible digital foundation. The insurer could now respond faster to business and regulatory needs while supporting more scalable participant experiences.
The modernization gives the insurer a foundation to evolve its retirement business without carrying forward the constraints of its legacy platform. It demonstrates how Cloud modernization for insurance can connect technology modernization with business agility, operational efficiency, and better participant experiences. As participant expectations and regulatory requirements continue to change, the cloud-native architecture can support faster product innovation, broader digital adoption, and scalable growth. It also creates a path to continuously optimize the retirement operating model as new cloud capabilities and automation opportunities emerge.
