Virtual machine capacity expansion and contraction method and device, computing equipment and computer storage medium

The invention discloses a virtual machine capacity expansion and contraction method and device, computing equipment and a computer storage medium. The method comprises the steps that S1, historical resource usage amount data of a virtual machine is acquired; s2, predicting the expected resource demand quantity of the virtual machine in the next period by using a time sequence prediction algorithm according to the historical resource usage amount data; s3, determining a capacity expansion and contraction strategy of the virtual machine according to the expected resource demand quantity of the next period and the current actual resource usage amount; s4, carrying out backward verification on the capacity expansion and contraction strategy of the virtual machine; if the verification is passed, executing S5; if the verification is not passed, skipping to execute S2; s5, judging whether a triggering condition of a virtual machine capacity expansion and contraction strategy is met or not; if yes, executing S6; if n
