Context sensing based cloud computing system mirror image preparation tool and method

The invention discloses a context sensing based cloud computing system mirror image preparation tool and method, and belongs to the field of cloud computing. The tool comprises a controller, at least one creator and at least one preparation device. The context sensing based cloud computing system mirror image preparation method comprises the following steps that the controller obtains a context and registers the context; the controller controls at least one creator in a creator list to create at least one mirror image of a cloud platform; and the controller receives mirror image completion information and then calls the preparation device to install at least one piece of software in the mirror image. According to the tool and method, while the system mirror image preparation efficiency is improved, the consistency, expandability and maintainability of a cloud computing system are ensured.
