Backup system and method that can determine a backup destination in consideration of disaster are provided. There are provided: a data acquisition unitthat acquires disaster information, network information, and node information; a replication group construction unitthat generates, based on the disaster information, and the like, replication group information including association information between a first node that stores original data and one or more second nodes that are candidates for backup destination of the original data, and saves the replication group information in a storage unit; a replication destination node calculation unitthat, when executing backup of the original data, calculates the second node as backup destination from the replication group; and a replication processing unitthat replicates and stores the original data into the storage of the second node.

Backup system, method therefor, and program

A system and method capable of efficiently using and operating resources and allowing a cluster satisfying requirements of functions/services provided to terminals to be configured of multi-access edge computing (MEC) servers are provided. A clustering systemincludes a monitoring unitconfigured to monitor a usage status of MEC servers and a network and store telemetry information in a storage unit, a cluster planning request unitconfigured to acquire non-telemetry information such as provision area information and requirement information of functions/services and deployment information of the MEC server, store the non-telemetry information in the storage unit, a cluster planning unitconfigured to set a virtual region including one or more bases satisfying a provision area and requirements on the basis of each piece of information in the storage unitand calculate a cluster plan for providing the functions/services from a plurality of MEC servers disposed at the base belonging to the virtual region, and a cluster construction unitconfigured to perform a clustering process on the basis of the cluster plan.

Clustering system and clustering method for providing services using multi- access edge computing servers

An access analysis system includes: a first analysis unit that analyzes validity of a user based on a characteristic of an operation of a terminal by the user regarding access via a network; a second analysis unit that based on communication regarding the access, analyzes normality of the communication; and a determination unit that determines validity of the access based on an analysis result from the first analysis unit and an analysis result from the second analysis unit, thereby improving the accuracy of determining the validity of access via the network.
