Abstract: A method and an apparatus for migrating a virtual machine across virtualization systems, and a system, where a first virtualization system in which a source virtual machine is located specifies a temporary address of a destination virtual machine. After a second migration tool of a second virtualization system migrates the to-be-migrated virtual machine to the second virtualization system to generate the destination virtual machine, a first migration tool of the first virtualization system controls a migration agent on the destination virtual machine to modify the address of the destination virtual machine to an address of the source virtual machine such that the address of the virtual machine remains unchanged before and after migration, thereby shortening service interruption duration caused by virtual machine migration.

Abstract: A redundancy method includes that a first disaster management function (DMF) device on a first site side receives a first request including identification information of a first virtual machine (VM) and a recovery point objective (RPO), allocates a maximum allowable delay time to each node that input/output (IO) data of the first VM passes through in a redundancy process, and sends a second request to a second DMF device on a second site side. The second request includes a maximum allowable delay time of a second replication gateway function (RGF) device on the second site side, and a maximum allowable delay time of an IO writer function (IOWF) device on the second site side and requests the second site side to perform redundancy on the first VM. Hence, the RPO requirements of the tenants can be satisfied in an entire redundancy process.

Abstract: In the website system of the application, when a client accesses a page of a website, a web server obtains an initial URL of a content file included in the to-be-accessed page and a version parameter of a current version of the website, generates a current URL of the content file, and adds the version parameter to a search part of the current URL of the content file, so that the client can obtain the content file from the web server according to the current URL. During version upgrade of the website, a developer does not need to change a path to a content file, does not need to manually change a URL of the content file, and does not need to update a name of the content file either. This improves website upgrading efficiency.
