With the rapid development of "Internet Plus" and the continuous improvement of living standards,people's demand for health services is increasingly growing,and "Online Medical" has become an irresistible trend.More and More hospitals also set up health care service platform through Web cluster to improve the quality of medical service.However,with the impact of massive user access and online medical big data,the Web cluster system is likely to cause the problem of uneven load and poor stability of the cluster,and even leads to security risks of the medical treatment.Aiming at the problems of medical health services in the Web cluster,this paper researches in accordance with the medical health service Web cluster load balancing strategy,designs and implements the load balancing workstation to improve medical and health services Web cluster concurrency and stability and provides better health care services for patients and doctors.Firstly,this paper introduces the background of constructing medical health service platform by the Web cluster and the significance of load balancing strategy in it,as well as the domestic and foreign development and research of medical service platform and load balancing strategy;Then describes the elements of Web cluster and the concept of load balance in detail and introduces the related technologies to lay the foundation for following research;Next this paper mainly describes the Web cluster load balancing strategy and the design and implementation of load balancing workstation in the cluster,including the Load Balancer Model,Node-capacity-evaluation Model,Node-prediction Model and a dynamic and static combinatorial predicted load balance method as well as the requirement analysis,architecture design and core module implementation of load balancing workstation in medical service platform;After the research and implementation,the experiments are designed to verify the validity of the models and algorithm of load balancing and the various functions of the workstations,and the test results are analyzed.Finally,the summary of the work,some of the needs to improve and in-depth study of the direction of the future are mentioned.The dynamic and static combinatorial predicted load balance method introduced in the paper is an effective method for Web cluster load balancing,and using the load balance workstation are able to improve the concurrency and stability of Web cluster,and provide better medical service for patients and doctors.
