Abstract: One example method includes receiving a query that recites a particular question for which a user who originated the query needs an answer, parsing the query to identify the question, identifying information that is responsive to the question, presenting the information to the user in a user-selectable form, and receiving, from the user, a selection of the information. In some cases, the information presented to the user may include one or more datasets, or one or more pipelines.

Abstract: One example method includes receiving a user request for a data set, and the user request includes information concerning user requirements for the data set, identifying data records that satisfy one or more of the user requirements, calculating a respective relative value for each of the data records, and the relative values are based in part on the user requirements, and providing access controls for each data record that enable tracing of accesses of the data record.

Abstract: A method includes receiving, at a content provisioning system from one or more client devices, one or more requests for file digests stored in respective data stores of a plurality of data stores in a distributed file system. The file digests are distributed across different ones of the plurality of data stores in the distributed file system. The method also includes determining a location of a given one of the requested file digests in one or more of the plurality of data stores and retrieving the given file digest from the determined location. The method further includes shuffling the distribution of the file digests across the plurality of data stores in the distributed file system.

Abstract: A method includes receiving, at a key management system from one or more client devices, one or more requests for cryptographic keys stored in respective clouds of a plurality of cloud service providers in a multi-cloud environment, the cryptographic keys being distributed across different ones of the respective clouds of the plurality of cloud service providers in the multi-cloud environment. The method also includes determining a location of a given one of the requested cryptographic keys on one or more of the clouds of the cloud service providers in the multi-cloud environment, retrieving the given cryptographic key from the determined location in the multi-cloud environment, providing the given cryptographic key to a given one of the client devices, and shuffling the distribution of the cryptographic keys across the clouds of the plurality of cloud service providers in the multi-cloud environment.

Abstract: A plurality of virtual content delivery network nodes are implemented using virtualization infrastructure of at least one processing platform. The processing platform is implemented using at least one processing device comprising a processor coupled to a memory. Each of the virtual content delivery network nodes comprises one or more virtual network function instances of a network functions virtualization framework of the virtualization infrastructure. The virtual content delivery network nodes may be dynamically added to, modified in and deleted from at least one virtual content delivery network in accordance with one or more specified policy criteria. A virtual content delivery network control plane may be arranged as an overlay relative to the network functions virtualization framework of the virtualization infrastructure. The virtual content delivery network control plane communicates with the network functions virtualization framework via one or more application programming interfaces.

Abstract: A method and computer program product for defining a first subnet for a first end portion of a physical network. The first subnet includes: a first NIC IP address, a first gateway IP address, and a first logical path connecting the first NIC IP address and the first gateway IP address. A second subnet is defined for a second end portion of the physical network. The second subnet includes: a second NIC IP address, a second gateway IP address, and a second logical path connecting the second NIC IP address and the second gateway IP address. A supernet is defined for a central portion of the physical network. The first subnet is coupled to the second subnet via the supernet to enable point-to-point routing of data through the physical network.

Abstract: Methods and apparatus for performing a data migration in a clustered computer system. In one aspect, the availability of the data being migrated is maintained during the migration. In another aspect, a data set is migrated by a transfer utility in one of the hosts in the cluster, and in response to a failure of the host, the migration is resumed without restarting from the beginning point of the data set. In a further embodiment, the hosts in the cluster have agents associated therewith to manage the data migration, and prior to taking at least one action associated with the data migration, the agents coordinate to ensure that the hosts in the cluster are prepared to have the at least one action taken.

Abstract: A method and apparatus for managing a migration of a data set from at least one first storage location to at least one second storage location, wherein read requests to the data set from at least one application program executing on a computer system initially are serviced from the at least one first storage location. The data set is copied from the at least one first storage location to the at least one second storage location, and then at least one aspect of the computer system is modified so that read requests to the data set are serviced from the at least one second storage location to achieve the migration. In one embodiment, the migration is subsequently undone by modifying the at least one aspect of the computer system so that read requests to the data set are again serviced from the at least one first storage location. In another embodiment, after the migration is performed, a determination is made as to whether to finalize the migration.
