Exploration and Application of ESB High-availability Architecture Construction Based on Hospital Information System / 中国医疗器械杂志

OBJECTIVE@#To solve the ESB bus performance and safety problems caused by the explosive growth of the hospital's business, and to ensure the stable interaction of the hospital's business system.@*METHODS@#Taking the construction of our hospital's information system as an example, we used AlwaysOn, load balancing and other technologies to optimize the ESB bus architecture to achieve high availability and scalability of the hospital's ESB bus.@*RESULTS@#The ESB bus high-availability architecture effectively eliminates multiple points of failure. Compared with the traditional dual-machine Cluster solution, the security is significantly improved. The nodes based on load balancing can be scaled horizontally according to the growth of the hospital's business volume.@*CONCLUSIONS@#The construction of the ESB bus high-availability architecture effectively solves the performance and security issues caused by business growth, and provides practical experience for medical information colleagues. It has certain guiding significance for the development of regional medical information.

Study on the Scheme for the Business Continuity of the Information System in Large Hospital / 医学信息学杂志

The paper analyzes the application scenarios of the information systems in large grade A class 3 hospitals by referring to domestic and overseas experience and standards,classifies and quantifies the demands for the business continuity of the Hospital Information System (HIS),and studies the technical schemes applicable for hospitals based on the core elements of the disaster recovery capability of the information system,including backup infrastructures,backup network,backup data processing system,data backup and protection,etc.

Application Research on Using High Availability Cluster Based on VMware in HIS / 医疗卫生装备

Objective To build high availability cluster using VMware to improve availability of hospital information system.Methods Virtual machines were installed in VMware server to act as backup servers.High availability software continuously detected status of physical servers using heartbeat signals.Results When physical servers failed,high availability cluster switched services automatically.The business switched to virtual machine quickly and smoothly.Conclusion High availability cluster based on VMware can improve HIS availability and lower implementation costs effectively.
