Cloud Resource Prediction Model Based on Adaptive Neural Network

In order to avoid the problem of poor utilization rate of container cloud resources due to the imbalance of resource supply and demand, it is necessary to forecast the resource demand in the future to schedule and allocate resources more accurately. Therefore, combined with the efficient learning ability of neural network and the adaptive learning rate, a cloud resource prediction model based on adaptive neural network is proposed. Firstly, the characteristics of historical data were mined by combining the characteristics of convolutional neural network (CNN) and long-term memory network (LSTM) to predict the future resource demand. Then the learning rate was adjusted adaptively according to the prediction of the model to improve the accuracy of model prediction. The test results with Microsoft Azure public dataset show that compared with CNN, LSTM and the neural network model without adaptive learning rate, the root mean square error decreases by 17.74%, 18.27% and 6% respectively, which proves the validity of the model.
