Optimized Cloud Architectures for Secure and Scalable Electronic Health Records (EHR) Management

Author : Kannan Srinivasan and R Lakshmana Kumar

The management of Electronic Health Records (EHR) is a critical component of modern healthcare systems, with cloud computing offering an efficient solution for storing and processing vast amounts of health data. This paper presents an optimized cloud-based architecture for secure and scalable EHR management. The proposed system integrates advanced security mechanisms, including Zero Trust Architecture and multi-factor authentication, with scalability features such as auto-scaling to handle fluctuating workloads. The system ensures high availability and efficient performance by employing flexible microservices and encryption protocols like AES-256 for data protection. The research evaluates the system’s performance based on key metrics, including system latency, throughput, availability, and security effectiveness (false positive rate and false negative rate). The results demonstrate that the proposed system outperforms existing cloud-based and on-premise EHR solutions, achieving lower latency, higher throughput, and greater availability, while effectively safeguarding sensitive healthcare data. Furthermore, the system ensures compliance with privacy regulations, such as HIPAA and GDPR, by implementing robust access control mechanisms and secure data transmission protocols. In conclusion, the proposed architecture provides a comprehensive and reliable solution for managing EHR data in cloud environments. The integration of security, scalability, and interoperability features ensures the system can meet the evolving demands of modern healthcare.
