Abstract: A system, method, and computer-readable medium for point of presence (POP) based traffic surge detection and mitigation are provided. The system detects a traffic surge for a target group of resources directed at a source POP based on the target group's rank shifts and volume changes among recent time intervals. The system mitigates the detected traffic surge by identifying destination POPs with spare capacity and routing at least a portion of incoming requests for the target group of resources to the destination POPs in accordance with their spare capacities.

Abstract: A technology is described for simulating communication expressions detected in speech data using virtual objects. An example method may include receiving speech data for a virtual object configured to simulate communication expressions provided by the speech data. The speech data may be analyzed for an indicator of a communication expression and communication mark data that includes an expression tag representing the communication expression may be generated. The speech data and the communication mark data may be transmitted to a simulation client to enable synchronization of an animated expression for the virtual object with the speech data using the expression tag in the communication mark data.

The logging entity may obtain log information from the firewall or other security device and store the log information such that it is accessible to the customer. Additionally, the log information may be provided to other services such as a metrics service or intrusion detection service.

Abstract: An image quality assessment solution analyzes an image quality and a correlation of an image to an item description associated with the item. The content quality assessment may assign a quality score to the image based on a composition of the image and/or correlation with the image description. The score may be based on a model that is trained to analyze images using a learning model. Based on the image score, a correlation score, or other scores, the user may be given feedback on how to improve an image. A service provider providing this service may use the score to influence recommendation results that use the images.

Abstract: Techniques are described for providing alternative media content to a client device along with primary media content.

Abstract: Systems and methods are described to enable adaptive handling of domain resolution requests originating from a virtual private cloud (VPC) networking environment. An administrator of the VPC can provide a set of rules specific to the VPC that designates how requests for a domain name should be handled. The rules may specify, for example, that a request for a given domain name should be routed to a particular domain name server, which may include a private domain name server, should be dropped, or should be routed according to a default behavior (e.g., a public domain name system). Resolution requests originating in the VPC can be associated with a VPC identifier. When an adaptive resolution system receives the request, it can retrieve rules associated with the VPC identifier, and apply the rules to determine further routing for the request.

Abstract: A processing device executes a first script, wherein the first script comprises one or more actions to be performed. The processing device determines that the first script comprises a reference to a second script stored in a remote data store. The processing device retrieves the second script over a network from the remote data store and executes the second script. The first script and the second script may be stand-alone scripts or scripts encapsulated within documents.

Abstract: Described herein is an inventory management system, and corresponding methods, in which robotic units are configured to execute at least a portion of a set of instructions in an automated manner. During execution of the set of instructions, robotic units may encounter tasks that they are unable to complete in an automated manner. The robotic units, upon encountering these tasks, may submit a request for manual operation to a control unit. In some embodiments, the request may be assigned to an available operator, which may take over control of the robotic unit using a remote manipulation device, to complete the task manually. Once the task has been completed manually, automated execution of the instructions may be resumed.

Abstract: Aspects of a data environment, such as various capacities of data stores and instances, can be managed using a separate control environment. A monitoring component of the control environment can periodically communicate with the data environment to obtain performance information. The information is analyzed, using algorithms such as trending and extrapolation algorithms, to determine any recommended scaling of resources in the data environment. The scaling can be performed automatically, or as authorized by a customer. A workflow can be instantiated that includes tasks necessary to perform the scaling. The scaling of storage capacity can be performed without affecting the availability of the data store.

Abstract: Methods and apparatus for configurable-capacity time-series tables are disclosed. A schedule of database table management operations, including at least an operation to change a throughput constraint associated with a table in response to a triggering event, is generated. The table is instantiated with an initial throughput constraint in accordance with the schedule. Work requests directed to the table are accepted based on the initial throughput constraint. The throughput constraint is modified in response to the triggering event. Subsequent work requests are accepted based on the modified throughput constraint.

Abstract: Techniques are disclosed for splitting a database partition into two partitions. In embodiments, where the partition is a hash partition, the partition is split at its logical midpoint, so that half of the partition's rows are placed in each split partition. Where the partition is a hash-range partition, a number of rows of the partition are sampled. Where enough samples fall on each side of the logical midpoint, the logical midpoint is again used as the split point. Where not enough samples fall on one side of the logical midpoint, then the median of the samples is used as the split point.

For instance, one or more vibration mitigators may be included to dampen vibrations that may affect a performance and functionality of the one or more components located within the cavity.

Abstract: The present document describes systems and methods that detect unauthorized transmission of data from internal networks to remote service providers, even when the transmission occurs over an encrypted connection. An exfiltration monitor is configured to monitor encrypted communications between clients within an internal network and a remote service provider. In various implementations, the exfiltration monitor associates the encrypted connections with account information, and applies exfiltration policies to the connections based at least in part on the associated account information. In additional implementations, the exfiltration monitor is provided with cryptographic keys that facilitate packet inspection of the encrypted connections. In many situations, the exfiltration monitor can use this information to discern between authorized use of a remote service, and unauthorized data exfiltration to the remote service.
