Cloud-Native API-Led Integration Using MuleSoft and .NET for Scalable Healthcare Interoperability

Abstract

Healthcare organizations urgently need scalable, API-led solutions to connect disparate systems and data silos. Standards such as Fast Healthcare Interoperability Resources (FHIR) and HL7 beacons for data-sharing interoperability. Integration effort is usually focused on business requirements, protocols, and data mapping but often leaves quality, perfor- mance, and security to consumers. These aspects can be better managed with a dedicated architecture that emphasizes rapid application scalability. A cloud-native API-led strategy based on MuleSoft’s Anypoint Platform and .NET is shown to bring together enterprise, process, and experience APIs to produce a semantically coherent product using discrete services anchored in FHIR. The approach also delivers the segregation of frontend and payload traffic essential for improving security and fault tolerance. This section describes the patterns proposed for an API-led design, discusses MuleSoft and .NET as the primary technologies, and analyzes a proof of concept that fulfills a typical initiative in the healthcare industry. Such implementations are usually produced in silos, focusing on a particular data source, consumer, or business issue while exposing very little of the data engine’s potential. A Layer 7 API–led design facilitates sharing of services and data, ensuring consistent data quality and validation through an omnipresent process. A central catalog governs API visibility and provides processes like OAuth2 token distribution for protecting privacy.
