S22: calling a capacity expansion application program interface when the operation index of the server exceeds a first preset threshold value;
for example, when the average CPU utilization of the server reaches 80%, the capacity expansion application program interface is called to implement automatic capacity expansion.
When the operation index is the request quantity, the method further comprises the following steps:
acquiring an average value of the request quantity in a preset time period;
and calling the capacity expansion application program interface when the current request quantity exceeds a preset ratio of the average value of the request quantity in a preset time period.
For example, when the ring ratio of the request amount to the average request amount in the preset time period (last week) exceeds 60%, the capacity expansion application program interface is called to realize automatic capacity expansion.

The standby servers are started one by one through the capacity expansion application program interfaces, the operation index is prevented from being monitored manually, the capacity expansion time is delayed by manually starting the standby servers, and the capacity expansion speed is increased.
The second method comprises the following steps: and judging the number of the standby servers to be started according to the specific numerical value of the operation index, and directly starting the standby servers with corresponding number according to the number of the started standby servers.
