Method, System, and Apparatus for Cloud Application Redundancy

A redundancy apparatus, comprising:

• a processor;
• a memory;
• a bus;
• and
• a communication interface,
• wherein the memory is configured to store a computer-executable instruction,
• wherein the processor is connected to the memory using the bus, and
• wherein when the redundancy apparatus runs, the processor executes the computer-executable instruction stored in the memory so that the redundancy apparatus executes the following steps:
• acquire first description information of a cloud application needing redundancy, wherein the first description information comprises information about a source network used at a production site by the cloud application needing redundancy and information about a source virtual machine used at the production site by the cloud application needing redundancy;
• generate second description information of the cloud application needing redundancy according to the first description information, wherein the second description information comprises information about a backup network used at a redundancy site by the cloud application needing redundancy and information about a backup virtual machine used at the redundancy site by the cloud application needing redundancy;
• and
• provide the second description information for the redundancy site, so that the redundancy site recovers the cloud application needing redundancy according to the second description information.

A redundancy system, comprising:

• a cloud management module at a production site;
• a redundancy management module;
• and
• a cloud management module at a redundancy site,
• wherein the cloud management module at the production site is configured to record first description information of a cloud application needing redundancy,
• wherein the first description information comprises information about a source network used at the production site by the cloud application needing redundancy and information about a source virtual machine used at the production site by the cloud application needing redundancy,
• wherein the redundancy management module is configured to:
• acquire the first description information from the cloud management module at the production site;
• generate second description information of the cloud application needing redundancy according to the first description information, wherein the second description information comprises information about a backup network used at the redundancy site by the cloud application needing redundancy, and wherein information about a backup virtual machine used at the redundancy site by the cloud application needing redundancy;
• and
• register the second description information with the cloud management module at the redundancy site, and
• wherein the cloud management module at the redundancy site is configured to:
• receive registration information, wherein the registration information carries the second description information;
• and
• recover the cloud application needing redundancy at the redundancy site according to the second description information.
