[Abstract]:With the promotion of the new medical reform, the construction of hospital information has become the key development direction of the medical and health industry. With the increasing demand for medical and health services, the traditional hospital information has been unable to respond flexibly and effectively. Its architecture design and management mode can not meet the development requirements of the current digital hospital construction. The core technology and service mode of cloud computing are applied to the hospital information construction to realize the overall deployment of the platform and the centralized management of resources. Software and hardware are configured on demand to meet the requirements of reliability, scalability, high availability, security and on-demand service in practical applications. The purpose of this paper is to study the application of cloud computing core technology in hospital informatization, to integrate "cloud architecture" with hospital information system, and to put forward the management idea of unified operation and maintenance platform. The basic information platform is built by virtualization technology to improve the utilization ratio of resources, and the high availability of the platform is realized by using Pacemaker cluster management software and HAProxy load balancing, which provides the guarantee for the 7 脳 24 hours uninterrupted service mode in hospital. To realize the transformation from the traditional hospital information construction to the new hospital information service mode. Firstly, this paper expounds the development status of the traditional hospital information construction and the problems to be solved urgently, such as the "chimney" deployment model, and so on. This paper analyzes the application status of cloud computing in the medical industry at home and abroad, analyzes the application advantages of cloud computing core technology and architecture in hospital information construction, and studies the OpenStack open source cloud computing platform in detail. Secondly, The operation and maintenance management platform based on Web is designed. The open source platform and extensible deployment are used to improve the resource performance and utilization, and reduce the construction cost and maintenance cost of IaaS platform. At the same time, the design of OpenStack multi-node high availability architecture is carried out. Finally, the multi-node deployment of OpenStack open source cloud platform is carried out, which is based on Web operation and maintenance management platform, computing, network, storage of RabbitMQ message queue. The function and high availability of the private cloud platform are tested. This paper is an attempt to apply cloud computing to hospital informatization, to change the construction mode of traditional hospital informatization, and to deploy high availability. The scalable private cloud platform provides some valuable experience for large-scale deployment of hospital private cloud platform.
