Claim 0:
1. A method for handling large-scale host failures on a cloud platform, comprising:
S100, dividing hosts in a cluster into host groups, and configuring a corresponding failed host queue for each host group;
S200, setting initial priority values for cloud hosts in the hosts, and setting evacuation count thresholds for the cloud hosts;
S300, detecting failed hosts, arranging the failed hosts in failed host queues according to priorities of the failed hosts, and arranging the cloud hosts in the failed hosts according to priority values of the cloud hosts;
S400, handling, by the host group, the failed hosts in the corresponding failed host queue according to an arrangement order of the failed host, and handling, by the host group, the cloud hosts according to an arrangement order of the cloud hosts; in a case where evacuation of a cloud host fails, re-determining a priority value of the cloud host according to a priority value change rule;
S500, detecting evacuation capability of the host group corresponding to each failed host queue, and disabling a failed host queue having poor evacuation capability;
S600, arranging failed hosts in the disabled failed host queue into remaining failed host queues according to priorities of the failed hosts; and
S700, enabling a failed host queue meeting a condition.
