Monolith coupling in health insurance platforms impedes growth as business environments change. The Migration Strangler Pattern offers a decoupling strategy, but selection of additional patterns lacks empirical support. Qualitative architectural analysis identifies and describes a catalogue of 14 patterns that address remaining decoupling concerns across business areas such as observability and monitoring, deployment and operations, risk management, and team organization. A synthesis of nine architectural principles supports the patterns. Evidence from three health insurance case studies assesses pattern applicability, clarifies trade-offs, and expresses cost-benefit considerations.
Introduction
Monolith coupling in health insurance platforms limits scalable growth in increasingly volatile business environments. The migration-supporting Migration Strangler Pattern offers a single decoupling pathway, but additional patterns for related concerns across operational domains remain poorly substantiated. A qualitative architectural analysis identifies and describes a pattern catalogue covering 14 additional transformation avenues associated with observability, deployment and operations, CI/CD, security and compliance, and team organization. The catalogue is framed by a synthesis of nine architectural principles for supporting decoupling outside direct functionality. Patterns are grounded in practical experience from three health-insurance-sector case studies that attest applicability, clarify trade-offs, and express cost-benefit considerations.
