Method and device for expanding and shrinking capacity of cloud resources

The embodiment of the invention provides a cloud resource capacity expansion and contraction method and device, and the method comprises the steps: obtaining the transaction data of a cloud server in a current period, and the transaction data in the current period comprises the number of transaction requests in the current period, and the transaction time consumption of each transaction request in the current period; determining a transaction timeout proportion in the current period according to the transaction data, wherein the transaction timeout proportion is the proportion of the transaction request of which the transaction time consumption in the current period is greater than a preset threshold value in the current period; and carrying out capacity expansion and shrinkage on the resources of the cloud server through the transaction timeout proportion. According to the invention, the problem of resource waste in capacity expansion and shrinkage of cloud resources is solved. 本发明实施例提供了一种云资源的扩缩容方法及装置，包括：获取云
