Modernizing Insurance with digiRunner—Bridging Legacy Systems and Microservices

Mission Goals: Transforming Legacy Insurance Systems into Agile Ecosystems with a Small Kernel and Microservices

The insurance industry is undergoing a significant transformation, with many organizations striving to replace rigid legacy systems with modern, microservices-driven architectures. The “small kernel with innovative microservices around” strategy is at the heart of this transformation, combining a stable, centralized core system (the kernel) with agile microservices to enhance scalability, responsiveness, and customer-centric innovation. digiRunner API Management serves as a pivotal business middle platform, enabling insurers to overcome legacy infrastructure challenges and seamlessly adopt this modern architecture.

Challenges in Transitioning from Legacy Systems to Microservices

Legacy System Limitations

• Inflexibility of Monolithic Systems: Legacy mainframe systems are often tightly coupled and difficult to modify, making integration with modern microservices architectures both complex and costly.

• Technical Debt: The effort required to overhaul entrenched legacy infrastructures often creates significant technical and operational challenges.

• Risk of Downtime: Migrating from monolithic systems to microservices can risk disruptions in critical operations such as claims processing and policy management.

Data Synchronization and Real-Time Processing

• Disconnected Systems: Legacy environments frequently lack real-time capabilities, leading to inconsistent data updates and delays in customer service.

• Siloed Processes: Data silos impede seamless communication between departments, slowing decision-making and service delivery.

Security and Regulatory Compliance

• Increased Vulnerabilities: A distributed system introduces new security risks, especially when transitioning from centralized legacy systems.

• Regulatory Hurdles: Compliance with stringent insurance industry regulations requires advanced monitoring, governance, and audit capabilities.

digiRunner acts as the essential business middle platform, addressing the complexities of integrating legacy systems with a modern microservices architecture. By serving as a bridge, digiRunner enables insurers to modernize incrementally, reducing risks while maximizing operational efficiency and innovation.

Empowering the Small Kernel Core

• API Gateway: Serves as a central hub for managing communication between legacy kernels and new microservices. It ensures secure, reliable routing, load balancing, and data exchange.

• Role-Based Access: Implements robust, token-based authentication to secure sensitive core operations such as underwriting and claims processing.

• Operational Resilience: digiRunner’s middleware stabilizes legacy systems, enabling insurers to build flexible, scalable microservices around a reliable core.

Incremental Microservices Integration

• Dynamic API Registration: Simplifies the onboarding process for new microservices with batch imports and OpenAPI standards, reducing time-to-market.

• Decoupled Migration: digiRunner facilitates gradual migration by allowing insurers to build, scale, and test microservices independently without disrupting the legacy core.

• Smart API Caching: Enhances performance by reducing redundant calls to the legacy core, improving overall system efficiency.

Enabling Real-Time Data Flow and Communication

• Real-Time Monitoring: Ensures synchronization between legacy systems and microservices, reducing data inconsistencies.

• Traffic Management: Dynamically distributes requests across microservices to balance workloads and avoid bottlenecks.

• Mock API Testing: Provides a safe environment for pre-deployment testing, ensuring seamless operation post-integration.

Advanced Security and Governance

• Unified Authentication Protocols: Ensures consistent security across both legacy systems and microservices with OAuth 2.0 and token-based frameworks.

• Regulatory Compliance Tools: Provides real-time analytics, automated audits, and compliance dashboards to meet insurance industry standards.

• Policy-Based Management: Groups APIs into logical clusters to simplify governance, enforce security measures, and align with organizational policies.
