A collection of image deviations that includes pair-wise image deviations between pairs of images are identified. A pair of images includes a first image from the first images and a corresponding second image from the second images. An image deviation indicates a portion of the second image identified as differing from a spatially corresponding portion of the first image. The image deviations are grouped into deviation groups. At least some of the second images are associated with at least some of the deviation groups. A subset of the second images corresponding to a deviation group is output responsive to a selection of an indication of the deviation group.

Abstract: Lease-based consistency may be implemented for databases to handle failovers. A database node may obtain a consistency lease that describes a point in time determined from a time-to-live amount added to a consistent point in time for database data. While the consistency lease is valid, Multi-version Concurrency Control (MVCC) snapshots assigned by the database node can be used to handle requests to access the database data. Once expired, the database node may have to renew the consistency lease in order to continue to handle write and read requests.

Abstract: Reliability monitoring can be performed for compute instances in a cluster with auto-scaling capability. Such monitoring can analyze state information for various instances, such as spot instances, to determine when an interruption or termination is to occur. An impact assessor can determine the impact on performance due to any such interruption or termination, and if necessary to maintain at least a minimum level of performance then an action performer can obtain additional or alternate instances, which may be of a different type, to make up for lost capacity. Any tasks being performed can be migrated to the newly-allocated instances without any failures or significant impact on performance, and the previously-utilized instances can be released corresponding to the termination or interruption.

Abstract: In described examples, an integrated circuit (IC) includes a first temperature sensor, a processor, a second temperature sensor, and a reset module. The first sensor senses a first body temperature of the IC. The processor asserts a thermal shutdown signal if the first body temperature exceeds a first threshold. In response to the thermal shutdown signal, the second sensor asserts a reset request signal and senses a second body temperature of the IC. If the second body temperature is less than a second threshold, the second sensor asserts a reset end signal. The reset module outputs a system reset signal to the first sensor and the processor if the reset request signal is asserted, and outputs a system recovery signal if the reset end signal is asserted. The first sensor and the processor deactivate if the system reset signal is asserted, and activate if the system recovery signal is asserted.
