Abstract: Network pathways are identified to transfer packets between a pair of regional virtual traffic hubs of a provider network. At a first hub of the pair, a first action is performed, resulting in a transmission of a packet received from a first isolated network to the second hub along a pathway selected using dynamic routing parameters. At the second hub, a second action is performed, resulting in the transmission of the packet to a destination within a second isolated network.

Abstract: Packets of a network flow are received at a virtual traffic hub, which includes an action implementation layer at which routing actions generated at a decisions layer are performed. One or more properties of one or more packets of the flow are analyzed at the virtual traffic hub. An indication of an anomaly of the flow, detected based at least in part on the analysis, is provided to one or more destinations.

Abstract: Techniques for actor and thread message dispatching are described herein. In some examples, a computing system may include multiple actors and multiple processing threads. Upon receiving an incoming message associated with one of the actors, a dispatching component may select one of the multiple processing threads within the computing system to which to dispatch the message for processing. If the associated actor is already assigned to one of the processing threads, then that processing thread may be selected for processing of the message. By contrast, if the associated actor is not already assigned to one of the processing threads, then a processing thread may be selected based on various factors, such as a set of priorities associated with the processing threads.

Abstract: A computer implemented method includes determining a hierarchical graph of a network of entities. The method further includes determining event data from a plurality of events. The method also includes applying a plurality of statistical models on the event data corresponding to each of the plurality of the events and the hierarchical graph.

The devices may be represented as environment objects in the digital content. A location may be identified within the digital content that corresponds to environment objects representing the devices. Audio may be received from the devices. The audio may be transmitted to the devices for directional audio playback. The audio may be directed to correspond with the virtual location of the environment objects in the digital content.

Abstract: A data storage system implements aggregation, bifurcation, and/or reduction techniques to improve the efficiency of processing data storage requests. Data storage requests and/or their associated payloads may be aggregated based on one or more parameters. Data to be the stored and the associated commands may be separated so as to optimize a system's throughput and latency for each. Furthermore, extraneous commands and requests may be reduced or eliminated based on heuristics associated with the requests and the data.

Abstract: This application describes techniques for providing computer vision for manual services. In some instances, a remote system may determine that a current time is within a threshold period of time of a scheduled service and, based on the determination, send a first message requesting image data to a camera apparatus located within an environment. After sending the first message, the remote system may receive image data associated with the environment from the camera apparatus and use the image to detect an object within the environment. The remote system can then send a second message to a device of a guest and a third message to a device of a user, where each of the second message and the third message indicates that the object is within the environment. In some instances, the object can include an animal while in some instances, the object can include a person.

Abstract: A method of adding a power feed to electrical systems includes coupling a set of input lines to a power source such that the input lines are connected to at least one phase of AC power from the power source, and coupling a set of backfeed lines to an output receptacle in a power distribution unit. The output receptacle may be connected in parallel with at least one other output receptacle that is supplying primary power to systems in the data center. The set of backfeed lines and the set of input lines may be tested to determine a match between a pair of lines in the set of backfeed lines and a pair of lines in the set of input lines. Determining the match may include matching the phase of the pair of backfeed lines with the phase of the pair of input lines.

Abstract: Various systems and processes may be used for virtual disk importation. In particular implementations, systems and processes for virtual disk importation may include the ability to receive a request from a customer of a service provider network to import a virtual disk, which is accessible over a communication network, into the service provider network. The systems and processes may also include the ability to download a portion of a virtual disk file corresponding to the virtual disk, determine the type of the virtual disk by analyzing the downloaded portion, and determine the size of the virtual disk by analyzing the downloaded portion. The systems and processes may further include the ability to determine whether the virtual disk is supported by the service provider network based on the determined type of the virtual disk and download the virtual disk if the virtual disk is supported by the service provider network.

Abstract: A video tagging system that can generate tags corresponding to associations of object-related keywords mentioned in a video to time instances in the video is described. The video tagging system identifies a particular object associated with a video. Using a transcription of audio content within the video, the video tagging system determines a keyword mentioned in the audio content that is associated with the object and a time instance within a timeline of the video when the keyword is mentioned. The video tagging system generates a tag that associates the keyword with the time instance and sends an indication of the tag to a user device. Once the video is displayed on the user device, the user can search for the keyword. This prompts the user device to display a marker indicating the time instance when the keyword is mentioned.

Abstract: Techniques for intelligent use of multiple virtualized resources via deep-inspection weighted round robin are described. Hardware resources shared between multiple clients can be intelligently selected between by the clients to perform operations. Weights of operation queues for the hardware resources that are assigned to instances can be provided to the clients to give the clients insight into how busy particular hardware resources are and what types of operations the hardware resources will be performing. In some embodiments, the clients can make use of a weighted round robin scheme to select between candidate hardware resources, allowing clients to effectively distribute operations between different hardware resources.

Abstract: A voice controlled assistant has a housing to hold one or more microphones, one or more speakers, and various computing components. The housing has an elongated cylindrical body extending along a center axis between a base end and a top end. The microphone(s) are mounted in the top end and the speaker(s) are mounted proximal to the base end. The microphone(s) and speaker(s) are coaxially aligned along the center axis. The speaker(s) are oriented to output sound directionally toward the base end and opposite to the microphone(s) in the top end. The sound may then be redirected in a radial outward direction from the center axis at the base end so that the sound is output symmetric to, and equidistance from, the microphone(s).

Abstract: At the request of a customer, a distributed computing service provider may create multiple clusters under a single customer account, and may isolate them from each other. For example, various isolation mechanisms (or combinations of isolation mechanisms) may be applied when creating the clusters to isolate a given cluster of compute nodes from network traffic from compute nodes of other clusters (e.g., by creating the clusters in different VPCs); to restrict access to data, metadata, or resources that are within the given cluster of compute nodes or that are associated with the given cluster of compute nodes by compute nodes of other clusters in the distributed computing system (e.g., using an instance metadata tag and/or a storage system prefix); and/or restricting access to application programming interfaces of the distributed computing service by the given cluster of compute nodes (e.g., using an identity and access manager).

Abstract: An electronic workspace may be created from multiple viewer devices. The viewer devices are coordinated so that each exhibits a different visual identification characteristic such as a distinct or unique color. Content can be assigned by way of a user interface in which individual viewer devices are represented by visual icons that exhibit the same visual identification characteristics as the respective viewer devices, so that a user may easily distinguish between the available viewer devices.

Abstract: Data within a database partition that is being migrated may be made available for access. Data within a database partition may be selected for migration. Writes to the selected data may be prevented while the data is being migrated. Writes to other data, or read access any of the partition, may be allowed during the migration of the selected data. Rollback events may be detected for a database partition that is being migrated, halting the further selection of data for migration and deleting the successfully migrated data at the copy of the database partition being created.
