Abstract:
1. A failure recovery method for an information processing service provided by an information apparatus, the method comprising: providing a virtual machine image generation apparatus coupled to the information apparatus, and a virtual machine execution apparatus coupled to the virtual machine image generation apparatus; generating and storing, by the virtual machine image generation apparatus, a virtual machine image based on system data and hardware configuration information which enable implementation of the information processing service at a time of normal operation of the information processing service; when a content of the system data and the hardware configuration information is changed, transmitting, by the information apparatus, the changed content to the virtual machine image generation apparatus; updating, by the virtual machine image generation apparatus, the stored virtual machine image to a changed virtual machine image according to the changed content; when a failure occurs in the information processing service, acquiring, by the virtual machine execution apparatus, the virtual machine image from the virtual machine image generation apparatus, providing hardware resources to the virtual machine; and implementing, by the virtual machine execution apparatus, the virtual machine which provides the function of the information processing service by emulating the information apparatus based on the acquired virtual machine image.
