Multi-Layered Security Architecture for IRIS Deployments on AWS with InterSystems IAM

Introduction In today's rapidly evolving threat landscape, organizations deploying mission-critical applications must implement robust security architectures that protect sensitive data while maintaining high availability and performance. This is especially crucial for enterprises utilizing advanced database management systems like InterSystems IRIS, which often powers applications handling highly sensitive healthcare, financial, or personal data. This article details a comprehensive, multi-layered security architecture for deploying InterSystems IRIS clusters on AWS using Kubernetes (EKS) and InterSystems IAM. By implementing defense-in-depth principles, this architecture provides protection at every level—from the network perimeter to the application layer and data storage. Why a Multi-Layered Approach Matters Single-layer security strategies are increasingly inadequate against sophisticated attack vectors. When one security control fails, additional layers must be in place to preven
