Problems solved by technology

The existing technology ignores the load level inertia at each specific moment, so that the prediction module cannot predict the possibility of sudden changes at the moment to be predicted in time, resulting in a certain hysteresis in the prediction
In addition, if only the time-based prediction method is used, for an abnormal day, the prediction method cannot know the abnormal situation of the day, and the prediction calculation is still performed according to the original rules, and the obtained prediction results will be separated from the actual virtual machine operation status of the day. , leading to serious over- or under-forecasting, resulting in serious waste of resources, or cloud platform turbulence due to under-forecasting
[0010] In general, the current virtual machine load prediction method has a certain lag, poor timeliness, and low prediction accuracy and flexibility
