Abstract: The present application relates to the field of cloud computing technologies. In one example method, when a cloud management device scales up a new execution device, before the execution device is successfully scaled up, that is, before a data routing table of each execution device is updated, the cloud management device sends an IP address of the new execution device to a load balancer, so that the new execution device can receive a service request allocated by the load balancer. When the execution device processes the service request, and if a data module is required to process the request, the execution device still allocates the data module according to a previous data routing table.
