  • Publication number: 20210064476
    Abstract: A system that implements a data storage service may store data for a database table in multiple replicated partitions on respective storage nodes. In response to a request to back up a table, the service may back up individual partitions of the table to a remote storage system independently and (in some cases) in parallel, and may update (or create) and store metadata about the table and its partitions on storage nodes of the data storage service and/or in the remote storage system. Backing up each partition may include exporting it from the database in which the table is stored, packaging and compressing the exported partition for upload, and uploading the exported, packaged, and compressed partition to the remote storage system. The remote storage system may be a key-value durable storage system in which each backed-up partition is accessible using its partition identifier as the key.

  • Patent number: 10841119
    Abstract: A technology is described for operating a device shadowing service that manages device representations for physical devices that are network addressable. An example method may include associating a device representation with a representation type, where the device representation represents a copy of a state of a physical device in network communication with a device shadowing service that maintains the device representation, and the representation type may define a command that can be invoked through the device representation. After the device representation has been associated with the representation type, the command may be invoked through the device representation. Invoking the command may involve identifying the representation type associated with the device representation and determining that the command is supported by the representation type. Thereafter, the command may be executed.

  • Patent number: 10497038
    Abstract: A website (“Teratrees”) is described where a person can upload pictures of trees or shrubs which they have recently planted and have them displayed in their personal profile. Validation of the tree is obtained by a voucher code that is entered into the website. Once the tree has been uploaded to the website it appears in the ‘Planted Trees’ section and can be offered to the Market at a price set by the planter. Another user can then purchase (using a virtual currency with real financial value) this tree from the Market and own it—whereupon it appears in their profile under ‘Owned Trees’. This is virtual ownership within the context of the website. The user who owns this tree can offer the tree again on the Market if desired, while further transactions are also possible. Users who plant and own trees are rewarded with points and ranking.

  • Publication number: 20180322017
    Abstract: A system that implements a data storage service may store data for database tables in multiple replicated partitions on respective storage nodes. In response to a request to restore a given table that was backed up in a remote storage system (e.g., key-value durable storage system), the service may create a new table, and may import a copy of each of the partitions of the given table from the remote storage system into the new table. The request to restore the table may specify a modified value for a configuration parameter for the table or for one of its partitions. The service may apply the new configuration parameter value to the table or its partitions during the restore operation. The new configuration parameter value may indicate an increase or decrease in storage capacity or throughput capacity, and its application may automatically trigger a partition split or move operation.

  • Patent number: 10027694
    Abstract: Systems and methods are described to enable detection of network attacks in communication networks. An attack detection system receives information regarding network traffic occurring at nodes of a communication network, and analyzes the information for anomalous traffic patterns. The attack detection system can use multiple, parallel metric evaluation units programmed to detect specific types of anomalies within traffic patterns. In one instance, a metric evaluation unit is programmed to detect changes in entropy for the traffic, as distributed according to a characteristic such as source address, protocol, or country of origin. Where the entropy of a set of traffic differs from historical averages by a large amount, such as by many standard deviations, the attack detection system may flag the traffic as indicative of an attack, even when the absolute volume of traffic has not changed.
