摘要
An information processing system includes first data center and second data center. The first data center includes first virtual machine server including first processor that executes virtual machine using an image file, first data server including second processor and first storage that stores a plurality of chunks, and first metadata server including third processor and second storage that stores metadata of the image file. The second data center includes a second virtual machine server including fourth processor, second data server including third storage and fifth processor, and second metadata server including sixth processor and fourth storage. The second processor transmits, to the second data center, a predetermined chunk of the plurality of chunks. The first processor stops the virtual machine after the predetermined chunk is transmitted. The third processor transmits the metadata to the second metadata server. The fourth processor activates the virtual machine.
