Micro-service resource configuration method based on cloud data center

The invention provides a micro-service resource configuration method based on a cloud data center. The method comprises the following steps: predicting the arrival rate of a micro-service chain request arriving at the cloud data center; calculating the number of server cores required by each micro-service based on the prediction result of the arrival rate of the micro-service chain request; according to the number of server cores required by each micro-service, expanding the micro-service based on a vertical and horizontal combined fine-grained scaling algorithm, and shrinking the micro-service based on a delay instance resource shrinking algorithm; and migrating the micro-service instances on the server with the low resource utilization rate to the server with the high resource utilization rate by utilizing an instance migration algorithm. According to the method, the micro-service architecture is used as a computing communication model, the internet application is used as a request model, the active micro-s
