Abstract: Embodiments of the present invention disclose a method for checkpointing and restarting a container status, including: at a checkpoint stage, acquiring and checkpointing configuration information of a first container, a control group status parameter of the first container, and an application program status parameter of the first container; and at a restart stage, reading the configuration information, the control group status parameter, and the application program status parameter, and configure a second container according to the read configuration information, the read control group status parameter, and the read application program status parameter. The embodiments of the present invention further disclose an apparatus for checkpointing and restarting a container status, so that an execution environment of a process in the container can be kept consistent before and after a checkpoint/restart operation.

Abstract: Embodiments of the present invention provide a method for migrating a user service, and relate to the field of communications, so that a user service is uninterrupted and service data of a user is not lost in a process of migrating an application program. The method includes: saving a user request link message sent by a client; after freezing an application program, saving socket status information corresponding to each current user link, and saving data packets in a socket input buffer and a socket output buffer that correspond to each current user link; and sending the user request link message to a standby server, so that the standby server generates a server socket according to the user request link message; and sending socket status information corresponding to the user link, and the data packets to the standby server, so that the standby server updates the server socket and buffer data.
