Engineering Insurance Portals of the Future: Modernizing Core Systems for Performance and Scalability

Abstract

Modernization of insurance portals has played a crucial role that legacy systems are unable to advance to meet the performance, scalability and flexibility requirements in the current digital insurance ecosystem. The paper presents an engineering design of developing next generation Java based insurance portals in Spring boot, Angular, and Microservices architecture, which is deployed on Pivotal Cloud Foundry (PCF) with both SOAP/REST API interoperability. Its system is created with the built-in SonarQube that handles the code quality and Jenkins that takes care of continuous integration/continuous deployment (CI/CD). The suggested model is based on three dimensions of modernization: (1) the architectural refactoring of legacy monoliths to microservices; (2) optimization of performance by use of distributed caches, containerization and load balancing; and (3) testing of scalability when simulated high-load conditions are provided. The findings show that the engineering productivity, stability, and performance are highly gained. There was also an increase in the team velocity that stood at 150 story points per sprint, which indicated improved planning and efficient development. There was also production stability, and release incidents were decreased by 62.5, and the MTTR was minimized by 66.3 indicating quicker issue fix. The quality of code increased due to an increase in the coverage of tests, the decrease in the number of static-analysis problems, and the growth of CI test pass rates. Performance of API was also found to be less latent and, more importantly, had increased success rates which proved to be a more reliable and scalable system. The study adds a blueprint of end-to-end modernization that incorporates cloud-native engineering, Devops automation, and microservice design concepts to speed up the digital transformation in the insurance sector.
