Design And Implementation Of Cloud-edge Collaborative Smart Home System Based On Microservices

With the arrival of the Internet of Everything era,the real-time processing requirements of massive data of IOT equipment challenge the centralized cloud computing architecture model:the cloud computing center undertakes all the computing and storage tasks of the system,and the data generated by the edge IOT equipment must be transmitted to the cloud for processing.On the one hand,the data of IOT equipment is not only limited to time-series numerical data,such as air pressure and humidity,but also includes flow data such as audio,video and image data,which cause the non-ignorable network transmission delay;on the other hand,the realization of system services depends on the cloud computing center completely,so the network jitter and interruption or cloud center failure will lead to the unavailability of services and reduce the user experience.Based on the above shortcomings,as a supplement to cloud computing,by giving data storage,computing and other functions to network edge nodes closer to user terminals and IOT devices,edge computing can reduce request response time,relieve the pressure of cloud center computing.And the mode that data will be processed where generated also improves the system security.Based on the multi-node smart home system,this paper introduces the edge computing model to provide users with perfect smart home equipment services.Then,aiming at the problems of computing collaboration,data collaboration and service collaboration between each edge node and cloud center after the introduction of edge computing model,a cloud edge collaborative scheduling mechanism is designed to make the cloud center and edge node work together and present an organic whole.In addition,aiming at the organic service organization form of independent deployment of cloud center and edge domain but cooperation,this paper completes the architecture design of unified cloud edge based on microservices to realize the service of system function modules and components,and solves the problems of service organization and governance after microservices.
