Container Migration Device, Container Migration Method, And Container Migration Program

Abstract: This container migration device causes an operating mode of a migration source proxy (120) to transition from a forwarding mode in which data transmitted from a request source container (110) that requests data processing are received, and the received data are forwarded to a migration source container (130), which is a request destination container, to a queuing mode in which the data are stored without being forwarded. After the migration source proxy operating mode has transitioned to the queuing mode and a migration destination container (150) has been activated, the container migration device causes the operating mode of the migration source proxy to transition to a queue delivery mode in which the stored data are delivered to a migration destination proxy. After the delivery of the stored data is complete, the container migration device changes a data transmission destination in the request source container from the migration source proxy to the migration destination proxy (140).
