Automated expansion method and apparatus

The invention discloses an automated expansion method and apparatus. The method comprises the following steps that S1, a cloud management platform obtains resource monitoring data from a cloud platform virtual data center; when the resource monitoring data meets a expansion condition, a resource expansion request is sent to a virtual resource scheduler, thereby enabling the virtual resource scheduler to send a resource allocation request to a resource management center; S2, the resource management center sends resource response information to the virtual resource scheduler according to the resource allocation request and virtual resources of a resource pool; and S3, the virtual resource scheduler allocates the corresponding virtual resources in the resource management center to the cloud platform virtual data center; and a resource cloud controller updates configuration information of the corresponding virtual resources of the resource management center. The method and the apparatus have the advantages that t
