The invention relates to a dispatching method for data center application services, which comprises the following steps of: obtaining the resource expense of the application services in a node; carrying out dividing on the node of the application services according to the resource expense of the application services for forming a fixed node and a transfer node; and dispatching the application service corresponding to the transfer node to the fixed node to be executed. The dispatching method and the system of the data center application services carry out division on the fixed node and the transfer mode according to the occupied resource expense of the application services, further, the application services in the transfer node are dispatched into the fixed node to be executed, and dynamic migration of the application services is carried out after the energy consumption sensing, so the dispatching of the application services has the energy consumption concept, and the node consumption number and the consumption generated by the application service dispatching are reduced. Therefore, the energy consumption of a whole data center is effectively reduced, and the efficient dispatching of the application services is realized.
