Abstract: The present invention relates to a method and a device for allocating resources, where the method includes: providing, by an infrastructure management node, options to a service application; determining, according to a selection result of the options fed back by the service application, physical resources of a level corresponding to the selection result; and creating virtual resources on the physical resources of the level corresponding to the selection result, and provides the virtual resources to the service application. Correspondingly, the present invention provides an infrastructure management node, thereby satisfying a deployment requirement of the service application and guaranteeing QoS of the service application.

Abstract: A data configuration method and device, and a data configuration rollback method and device are applied to the field of information processing technologies. The data configuration method includes: receiving a data configuration operation request, where the data configuration operation request includes an data insert request, a data delete request, or an data update request; allocating an operation serial number to the data configuration operation request; and recording the allocated operation serial number and data requested to be operated by the data configuration operation request, as a mapping relationship between a creation operation serial number, a deletion operation serial number, and the data according to the data configuration operation request.
