Abstract: A technology is described for resolving device credentials for a device. An example method may include receiving device credentials for management by a service provider. The device credentials may include authentication credentials and a device policy document that specifies permissions used to authorize resource actions requested by the device. In response to receiving a message requesting that a resource perform a resource action associated with the device, the device may be authenticated using the authentication credentials, and the resource action may be authorized using the permissions specified in the device policy document.

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.

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.

Abstract: A technology is described for operating a device shadowing service that manages commands associated with groups of device representations. An example method may include receiving a group command associated with a group of device representations managed by a device shadowing service. Device representations included in the group of device representations represent physical devices that connect to the device shadowing service over one or more computer networks. In response to the group command, the device representations included in the group of device representations may be identified and an instruction to perform an action indicated by the group command may be sent to the physical devices represented by the device representations. Thereafter, indications may be received that at least a portion of the physical devices performed the action.

Abstract: Systems and methods are disclosed herein for enforcing digital signature on a token useable by a network-addressable device to invoke service calls on services of a service provider. A device platform service of the service provider may receive service calls from the network-addressable device and cause one or more operations to be performed by other services of the service provider in response to receiving a notification that the request is authentic. An authentication service analyses a fingerprint associated with a request submitted by the device and determines whether it is a match to a fingerprint generated from cryptographic authentication information provided by the user in connection with registering the network-addressable device.

Abstract: A technology is described for managing dynamic groups of devices using device representations. An example method may include receiving a request for a dynamic group of device representations. In response to the request, a membership parameter used to identify member device representations included in the dynamic group of device representations may be obtained. Device representations may be queried using the membership parameter to identify member device representations that have a state that corresponds to the membership parameter, and the dynamic group of device representations may be generated to include identifiers for the member device representations.

Abstract: A technology is described for operating a device shadowing service that calculates an aggregated group state for a group of device representations. An example method may include receiving device states for devices represented using a group of device representations, where the devices connect over a network to a device shadowing service configured to manage the device states. In response to an event, device representations included in the group of device representations may be identified. Device states indicated by the device representations may be obtained and an aggregated group state for the group of device representations may be calculated using the device states indicated by the device representations.

Abstract: Technology is described for generating a search index. Device information associated with a customer may be identified. A device attribute included in the device information may be identified. The device attribute may include an attribute name and an attribute value. Key-value pairs may be formed for device attribute included in the device information. The key-value pairs may include a first key-value pair for the attribute name and a second key-value pair for the attribute value. The search index may be generated to include the key-value pairs for the device attribute included in the device information.

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.
