Enterprise Microservices Transformation for Global Insurance Leader

Challenge

A global insurance provider with operations in 30+ countries and over 50 million customers was struggling with an aging monolithic application architecture. Their core policy management and claims processing systems had become increasingly difficult to maintain, scale, and enhance, resulting in lengthy release cycles and growing technical debt.

Innovation Bottlenecks: New feature development took 8-12 months from concept to production

Scalability Issues: System performance degraded during peak periods, affecting customer experience

Regional Customization Complexities: Implementing country-specific regulatory requirements required extensive code changes

Integration Difficulties: Connecting with modern insurtech solutions and third-party services was cumbersome

Operational Inefficiencies: System outages during updates affected business continuity

Our team designed and implemented a scalable solution that modernized the client’s entire infrastructure while ensuring business continuity throughout the process.

Domain-based Microservices

Designed service boundaries based on insurance business domains (Policy Management, Claims, Billing, Customer Management, etc.)

API Gateway Layer

Implemented pattern for security, routing, and traffic management

Migration Approach

Established event bus for asynchronous communication between services

Polyglot Persistence

Selected appropriate database technologies for different service requirements

DevOps Automation

Built CI/CD pipelines for automated testing and deployment

Observability Stack

Implemented distributed tracing, logging, and monitoring

Implementation Process

The implementation followed Tarkasha’s proven methodology. Full compliance with all relevant regulations achieved and maintained
