Abstract: Technology for migration of a computing instance is provided. In one example, a method may include receiving instructions to initiate migration of the computing instance from a first host to a second host. A first message for sending to the first host may be generated which includes instructions to send data representing the computing instance to the second host. The first message may further include encryption information for use in deriving at least one key for encrypting communications to the second host from the first host. A second message for sending to the second host may be generated which includes instructions to receive the data representing the computing instance from the first host. The second message may further include information for use in deriving at least one key for decrypting communications from the first host. The first and second messages may be sent to the respective first and second hosts.

Abstract: Devices, systems and methods are disclosed for quickly readying a device when charging a dead battery. For example, a device may enter a hibernation mode when the battery becomes critically low and may resume normal operation from the hibernation mode when an external power source is connected to the device. While the battery is critically low but the device is connected to the external power source, the device may generate a visible indication, such as a watermark, and apply the watermark to content to allow a user to control the device while indicating to the user that the battery is critically low and should not be removed from the external power source. Thus, the device may reduce user-perceived latency from when the external power source is connected to when the device resumes system interactivity (e.g., being responsive to user input).

Abstract: Embodiments of the present disclosure are directed to, among other things, performing automated configuration of infrastructure components associated with a software system.

Additionally, a set of instructions configured to enable configuration of the software system may be generated. Based at least in part on execution of the set of instructions, remote feedback associated with the software system may be received. Additionally, in some examples, the infrastructure component may be configured based at least in part on the received remote feedback.

Abstract: Technologies are provided for distributing intra-network communications evenly across routers in a multi-tier network. Routers in a middle tier of the network receive data transmissions from a router in a lower tier of the network and determine that a destination of the data transmissions is another router in the lower tier of the network. Instead of routing the data transmissions to the destination router directly, the routers in the middle tier of the network route the data transmissions to other routers in a higher tier of the network. The routers in the higher tier of the network then route the data transmissions back to routers in the middle tier of the network, distributing the data transmissions evenly across routers in the middle tier that are connected to the destination router in the lower tier.

Abstract: A network gateway is implemented on behalf of a customer entity. The network gateway may be implemented using a distributed computer system and the network gateway may connect a network of the customer entity to a public communications network. The network gateway may include network-related services without the need for adding specialized hardware. The network gateway may be provisioned programmatically in response to instructions received from the customer entity. The network gateway may be provisionable and accessible over several different types of data connections. The network gateway, by virtue of being implemented on a distributed computer system, is scalable upon demand without additional input by the customer entity.

Abstract: A database may store an object comprising a hierarchy of sub-objects. Numeric identifiers may be assigned to names of the sub-objects and used in place of the names when writing the object to storage. Scalar values may be prefixed with length indicators. Collections may be prefixed with counts indicative of the number of elements in the corresponding collection. A portion of the object may be retrieved from storage by traversing a path from the root of the hierarchy to the desired portion. Length and count information may be used to skip over portions of the object during the traversal.

Abstract: Technology is described for sending subscription-based messages to devices. A message associated with a defined topic may be received. A first subset of devices may be identified that subscribe to the defined topic. A first subset of messages may be provided to a message queue for transmission to devices indicated in the first subset of devices. A second subset of devices may be identified that subscribe to the defined topic. A second subset of messages may be provided to the message queue for transmission to devices indicated in the second subset of devices. The second subset of messages may include an increased subset size as compared to the first subset of messages. The subset size may be increased at a rate to enable sending the message to the plurality of device subscribed to the defined topic within a defined time period.

Abstract: Techniques are provided herein for implementing transparent user interface elements. In at least one embodiment, a user interface comprising a section header element and a section entry element associated with the section header element may be presented. The section header element may have a background that is transparent and the section entry element may be presented as being below the section header element. User input corresponding to a scroll action may be received. The section entry element may be scrolled upward within the user interface based at least in part on the user input. It may be determined that the scrolling causes the section entry element to traverse the section header element. As a result, the background of the section header element may be altered from transparent to translucent and the section entry element may appear as if behind the section header element.

Abstract: A package launch system can be implemented to propel a package from an unmanned aerial vehicle (UAV) in a generally vertically descent trajectory, while the UAV is in motion. The package launch system can apply the force onto the package in a number of different ways. For example, flywheels, coils, and springs can generate the force that establishes the vertical descent path of the package. Further, the package delivery system can also monitor the package during its vertical descent. The package can be equipped with one or more control surfaces. Instructions can be transmitted from the UAV via an RF module that cause the one or more controls surfaces to alter the vertical descent path of the package to avoid obstructions or to regain a stable orientation.
