An example method for storing data includes providing a plurality of physical storage pools, each storage pool including a plurality of storage nodes coupled to a network. The method also includes mapping a partition of a plurality of partitions to a set of physical storage pools, where each physical storage pool of the set of physical storage pools is located in a different availability zone, and the storage nodes within an availability zone are subject to a correlated loss of access to stored data. The method further includes receiving a data management request over the network, the data management request being associated with a data object. The method also includes identifying a first partition of the plurality of partitions corresponding to the received data management request and manipulating the data object in the physical storage pools mapped to the first partition in accordance with the data management request.

Exemplary embodiments relate to methods, systems, and storage mediums for managing content storage and selection activities. The method includes aggregating content from content providers and presenting the content to a content device. The method also includes monitoring consumption of storage space with respect to storage capacity in the content device, relocating content contained in the storage space of the content device when a predetermined condition is met, and providing access to relocated content. The relocation is operable for freeing up the storage space of the content device.

The data processing times of data processing nodes are heterogeneous, and hence the execution time of a whole system is not optimized. A task is executed using a plurality of optimal computing devices by distributing a data amount of data to be processed with a processing command of the task for the plurality of optimal computing devices depending on a difference in computing power between the plurality of optimal computing devices, to thereby execute the task in a distributed manner using the plurality of optimal computing devices.

A method and an apparatus for sharing content are provided. Information about at least one content is transmitted to an external device. Information about associated content that have been searched for by the external device based on the transmitted information about the at least one content is received from the external device. Content to share with a second user device are selected from among the associated content based on a predetermined condition. Information about the selected content is transmitted to the second user device.

A system to facilitate management of surveillance devices, that are distributed over a monitored region, through a geographic information (GI) portal, having GI storage to store map data defining a geographic map of the monitored region. A GI manager unit (GIMU) to record, in the GI storage, asset position information with regarding locations for assets of interest within the monitored region. The GIMU obtains, from a remote surveillance device (SD) database, device-related records. The GIMU stores the device related records in the GI storage. The device records are associated with the surveillance devices installed in the monitored region. The device records include position tags that identify a location of the surveillance devices in the monitored region. The GIMU obtains, from a remote network (NW) database, network-related records. The GIMU stores the network related records in the GI storage. The network-related records associated with network devices are installed over the monitored region. The SD and NW databases are maintained and managed separately from the GI database by one or more independent management units. A display presents a geographic map of the monitored region with device markers and network links illustrated thereon. The device markers indicate positions of the surveillance devices relative to the geographic map. The network links indicate communications links between network devices. A user interface permits a user to select from the surveillance devices and network links. The GIMU makes available to the user the device related records and documents and the network related records and documents associated with the selected surveillance devices and network links.

An improved scalable object storage system allows multiple clusters to work together. In one embodiment, a trust and federation relationship is established between a first cluster and a second cluster. This is done by designating a first cluster as a trust root. The trust root receives contact from another cluster, and the two clusters exchange cryptographic credentials. The two clusters mutually authenticate each other based upon the credentials, and optionally relative to a third information service, and establish a service connection. Services from the remote cluster are registered as being available to the cluster designated as the trust root. Multi-cluster gateways can also be designated as the trust root, and joined clusters can be mutually untrusting. Two one-way trust and federation relationships can be set up to form a trusted bidirectional channel.
