The EIS Suite Data Model: Foundation for Flexibility
Module | Key Entities | Relationships |
---|---|---|
CustomerCore | Customer, Contact, Address | Customers own Policies; Contact links to Claims |
PolicyCore | Policy, Coverage, Vehicle | Policies linked to Customers and Billing |
BillingCore | Invoice, Payment, Refund | Invoices tied to Policies and Customers |
ClaimCore | Claim, Adjuster, Payout | Claims reference Policies and Payments |
This modular data model ensures each service can evolve independently, while maintaining data integrity and a 360° customer view.
High-Level Solution Design: Microservices & Event-Driven Architecture
Microservices
Each module is implemented as a standalone microservice using Java 21 and Spring Boot 3.5. This enables independent deployment, resilience, and rapid feature delivery.
Event-Driven Communication
Modules communicate via REST APIs and asynchronous events (Kafka or RabbitMQ). Key business events—such as policy issuance, payment receipt, or claim filing—are published and consumed across services, ensuring loose coupling, real-time data sync, and auditability.
API Gateway & Service Discovery
An API Gateway provides a single entry point for all consumers, while service discovery enables dynamic scaling and resilience.
Centralized Observability
Logging, monitoring, and tracing are centralized (e.g., ELK stack, Prometheus/Grafana) for proactive operations and rapid troubleshooting.
Caching Strategy
- API Gateway Caching: Caches frequently accessed API responses.
- Service-Level Caching: In-memory caches (e.g., Redis, Hazelcast) for hot data.
- Distributed Caching: Shared data (e.g., customer lookups) uses distributed cache for consistency.
- Cache Invalidation: Event-driven invalidation keeps caches fresh and accurate.
Benefits: Faster response times, reduced load, improved scalability, and resilience.

Example Customer Journey: How It All Comes Together
- Quote & Purchase: CustomerCore captures customer data; PolicyCore calculates premium and issues policy.
- Billing Setup: PolicyCore sends premium details to BillingCore, which generates invoices and manages payment schedules.
- Payment: BillingCore processes payments, updating policy status in real time.
- Mid-Term Changes: Customer or agent updates details; PolicyCore and BillingCore recalculate and synchronize changes.
- Claims: ClaimCore manages the claim process, validating policy status and payment history via PolicyCore and BillingCore.
- Renewal: PolicyCore and BillingCore coordinate to offer seamless renewals and billing.

Database Recommendations
Module | Recommended Database | Rationale |
---|---|---|
CustomerCore | PostgreSQL | Relational, strong consistency for customer data |
PolicyCore | PostgreSQL | Complex relationships, transactional integrity |
BillingCore | PostgreSQL | ACID compliance for financial transactions |
ClaimCore | MongoDB or PostgreSQL | Flexible schema for claims, or relational if needed |
- Event Store: Kafka (with persistent storage) for event sourcing and audit trails.
12-Factor Principles & Best Practices
- Codebase: One codebase per service, versioned in Git for traceability.
- Dependencies: Explicitly declared for reproducible builds.
- Config: Externalized for flexibility.
- Backing Services: Databases and brokers are attached resources, easily swapped or scaled.
- Build, Release, Run: Strict separation, with automated CI/CD pipelines.
- Processes: Stateless services for horizontal scaling and resilience.
- Port Binding: Each service exposes HTTP endpoints.
- Concurrency: Scale out via process model.
- Disposability: Fast startup/shutdown for robust deployments.
- Dev/Prod Parity: Consistent environments from development to production.
- Logs: Streamed to centralized log management.
- Admin Processes: One-off admin tasks run in isolated environments.
The Role of AI and Large Language Models (LLMs)
Modern insurance platforms like EIS Suite are supercharged with AI and LLMs to automate, optimize, and personalize every stage of the insurance lifecycle.
- Automated Customer Interactions: LLM-powered chatbots and assistants handle queries, guide users, and provide 24/7 support.
- Smart Document Processing: AI extracts and validates information from documents, speeding up onboarding and claims.
- Claims Triage & Fraud Detection: ML models flag suspicious activity and prioritize urgent cases.
- Personalized Recommendations: LLMs suggest tailored products and coverage.
- Process Automation: AI orchestrates workflows across modules.
- Advanced Analytics & Insights: AI-driven analytics inform decision-making.
- Regulatory Compliance: LLMs monitor communications and documents for compliance.
Integration Approach
- Microservice Integration: AI services are independent microservices, communicating via APIs and events.
- Event-Driven Automation: LLMs subscribe to business events and trigger automated actions.
- Continuous Learning: AI models retrain with new data from EIS Suite.
- Cloud-Native AI: Leverage cloud-based AI platforms for scalable, secure deployment.
Real-World Example
When a customer submits a claim, an LLM-powered assistant can:
- Instantly acknowledge receipt and provide next steps.
- Extract and validate claim details from documents.
- Flag potential fraud or missing information.
- Automatically update claim status and notify teams.
Implementation Recommendations
- Adopt microservices and event-driven design for agility and scalability.
- Use Java 21 and Spring Boot 3.5 for modern, maintainable code.
- Choose PostgreSQL for most modules; consider MongoDB for claims.
- Implement robust CI/CD and automated testing.

All modules interact via APIs and events, ensuring a seamless, real-time insurance experience for both customers and business users.
Microservices Context & Intercommunication
EIS Suite is architected as a set of independent microservices, each responsible for a distinct business capability. Services communicate via REST APIs for synchronous operations and Apache Kafka for asynchronous, event-driven flows.
Intercommunication Patterns
- Synchronous (REST): For real-time queries and direct service-to-service requests.
- Asynchronous (Kafka): For event-driven updates and decoupled workflows.
