A service-based elastic method in a cloud environment includes: detecting, by a cloud platform, an elastic event that occurs in running of a service; determining, by the cloud platform, a node that needs to be elastic and corresponds to the elastic event; determining, by the cloud platform according to an identifier of the node that needs to be elastic, a service topology diagram of the service, and an elastic method identifier of the service in a cloud service archive, a connection relationship that needs to be established, where the connection relationship includes a connection relationship between newly added node instances and a connection relationship between a newly added node instance and an existing node instance; and creating and running, by the cloud platform, the newly added node instance according to information of the node that needs to be elastic in the cloud service archive and the connection relationship. By means of the method in the present invention, running of a service can be optimized more effectively. |
