Abstract: A method for switching over a virtual application two-node cluster in a cloud environment, including: sending an association state of a shared EBS volume to the standby virtual machine; receiving a request for removing an association between the active virtual machine and the shared EBS volume; removing the association between the active virtual machine and the shared EBS volume; receiving a request for associating the shared EBS volume sent by the standby virtual machine; and associating the standby virtual machine with the shared EBS volume. A brain-split problem can be completely solved using the method and an apparatus disclosed in the embodiments of the present invention. In addition, dependence on a reference active node is no longer required, which can simplify deployment of an application two-node cluster and improve reliability of the application two-node cluster.
