Distribution of a service implemented by intra-connected virtual machines

摘要

A mechanism is provided for distributing a service implemented by a plurality of infra-connected source virtual machines on a source computing environment. Characteristic information of the service comprising an indication of the intra-connected source virtual machines and of each intra-connection between the intra-connected source virtual machines is discovered. The source virtual machines are copied into corresponding target virtual machines on a target computing environment. Reconfiguration information of at least one selected target virtual machine of the target virtual machines is saved that has a source identity of the corresponding source virtual machine in the source computing environment being reconfigured into a target identity of the at least one selected target virtual machine in the target computing environment. Each communication, addressed to each source identity by each target virtual machine intra-connected to a corresponding selected target virtual machine, is redirected to the corresponding target.

1. A method for distributing a service implemented by intra-connected source virtual machines on a source computing environment, the method comprising:
discovering characteristic information of the service comprising an indication of the intra-connected source virtual machines and of each intra-connection between the intra-connected source virtual machines, copying the source virtual machines into corresponding target virtual machines on a target computing environment according to the characteristic information of the service in response to a distribution command of the service, saving reconfiguration information of at least one selected target virtual machine of the target virtual machines having a source identity of the corresponding intra connected source virtual machine in the source computing environment being reconfigured into a target identity of the at least one selected target virtual machine in the target computing environment, and causing each communication, addressed to each source identity by each target virtual machine intra-connected to a corresponding selected target virtual machine, to be redirected to the corresponding target identity according to the characteristic information of the service and to the reconfiguration information of the at least one selected target virtual machine.
