Cross-domain calculation implementation method and system based on multiple data centers

The invention provides a cross-domain computing implementation method and system based on multiple data centers, and the method comprises the steps: an application layer packages a cross-domain computing request and issues the request to a master control node, and appoints a master cross-domain center and a plurality of slave cross-domain centers from the data centers; the master control node issues the request to the Web service in the main cross-domain center; the cross-domain executor submits the request job to a cross-domain execution engine of a main cross-domain center; the coordination calculator of the main cross-domain center analyzes the request operation and sends sub-calculation to the worker node of the slave cross-domain center through the coordination calculator of the slave cross-domain center for calculation, and a result is sent to the worker node of the main cross-domain center through the coordination calculator of the main cross-domain center for fusion calculation and stored in a data wa
