Business processing method and device

The invention provides a business processing method. The method comprises the following steps of: setting at least two virtual slot clusters in a practical slot cluster, wherein each of the virtual slot cluster comprises at least one slot under at least one node in the practical slot cluster; receiving a business logic task and determining a virtual slot cluster which executes the business logic task according to a data size of the business logic task; and executing the business logic task by using the virtual slot cluster. The invention furthermore provides a business processing device. According to the business processing method and the business processing device provided by the invention, the virtual slot cluster which executes the business logic task is determined according to the datasize of the business logic task, and expansion can be carried out on the slots of the virtual slot clusters, so that slot cluster expansion ability of the business processing device is enhanced, calculation requirements of s
