Abstract: Systems and methods are disclosed to implement a request routing layer of a service provider system, where the request routers are aware of different versions of a service implemented by the servers of the system. In embodiments, the request routers may discover the different versions of the service via periodic health messages or request responses from the servers. Requests are routed to the servers according to a routing policy that specifies the relative proportions of requests that are to be routed to each version. Version metrics generated from the requests may be captured and provided to a version change manager, which may update the routing policy based on the metrics, either increasing or decreasing the proportion of requests for the different versions. In embodiments, the request router may implement additional rules that control their routing behavior in response to detected error conditions.

Abstract: Techniques for detecting a predetermined waveform pattern in a signal received at a system are disclosed herein. A standard deviation and an average of the signal are calculated and used to determine a plurality of zones for the signal. A plurality of samples is obtained from the signal and one of the zones is associated with each of the samples. Transitions of the signal between the zones are identified based on the association of the zones with the samples. A predetermined waveform pattern may be detected in the signal based on the transitions between the zones. A notification may be generated indicating that the predetermined waveform pattern is detected based on a correspondence of the transitions of the signal matching a set of the predetermined transitions.

The personalized content may include features that allow a user to indicate a like or preference for an item and that can be customized based on, e.g., the extent of the user's social network or the influence the user has over other potential users of the catalog system. Systems and methods are also disclosed that use the social networking profiles to generate personalized messages that can be posted to social network contacts of the user to provide information about items for which the contacts may be interested.

Abstract: A service provider system may implement an approval service that manages approval requests received from other services on behalf of a customer organization and its end users. An administrator in the organization may create approval templates that define voting strategies at multiple approval levels and associate them with particular requests (individually, or by product, portfolio, project, action, message topic, workflow, or request type). The administrator may create approval groups whose members are authorized to respond to particular requests. Each approval template (or approval level) may include a different voting strategy or be associated with a different approval group. The approval system may support pre-notification of subsequent approval levels, auto-escalation, or auto-expiration. The approval service may employ a notification service to manage actionable notification messages that include approval requests. Members of approval groups may retrieve requests and select from available actions (e.g.

Abstract: An HSM management hub coordinates the distribution and synchronization of cryptographic material across a fleet of connected hardware security modules (“HSMs”). Cryptographic material is exchanged between HSMs in the fleet in a cryptographically protected format. In some examples, the cryptographic material is encrypted using a common fleet key maintained by the HSMs in the fleet. In other examples, the cryptographic material is protected using asymmetric cryptographic keys that are associated with the members of the HSM fleet. The HSM management hub may be used to divide the HSM fleet into subdomains by providing domain keys to subsets of HSMs within the HSM fleet. Cryptographic information that is encrypted with particular domain keys can be distributed across the entire HSM fleet, and restricted to use by authorized HSMs that are in possession of the particular domain keys.
