Abstract: The techniques disclosed herein enable systems to safely deploy a plurality of upgrade variants to different resource units that provide a service by utilizing small-scale deployment and validation. To deploy upgrade variants, a system receives a selection of upgrade variants from a feature group and automatically selects an appropriate set of resource units at which to deploy the upgrade variants. The system is further configured to collect and analyze telemetry data from the set of resource units to determine if any problems have occurred as a result of the deployed upgrade variants. By analyzing the telemetry data, the system can also identify one or more upgrade variants that are causing the problems. In response, the system can remove the identified variants and proceed with deployment of the remaining upgrade variants.

Abstract: Described is a technology by which an email filtering service or other gateway includes hybrid proxy and store-and-forward logic. A message is initially processed with proxy logic. If the proxy logic is unable to complete filtering/scanning of a message within a timeout period, the store-and-forward logic is invoked to complete filtering/scanning of the message. The store-and-forward logic also may be invoked if a delivery attempt made by the proxy logic fails or does not complete prior to a delivery timeout period. When such a condition is met, the store-and-forward logic accepts the message, including storing the message, sending a response that indicates the message was accepted, and closing the connection over which the message was received. The store-and-forward logic may complete any scanning if not completed by the proxy logic, and takes over delivery responsibilities.

Abstract: The present invention extends to methods, systems, and computer program products for adaptive electronic message scanning. Embodiments of the invention relate to dynamically (and potentially unpredictably) varying the depth/thoroughness of classifying electronic messages to protect against undesirable message content (e.g., SPAM, viruses, digital leakage, etc.). A minimum effectiveness is maintained and, when available resources permit, can be exceeded to provide increased protection. An optimal subset of available message classification rules can be selected on a per message basis. The selection of rules is based on available system resources, minimum desired effectiveness (e.g., defined in a Service Level Agreement (“SLA”)), and rule characteristics. Feedback loops can be used to optimize selected classification rule subsets.

Abstract: The present invention extends to methods, systems, and computer program products for automatically generating and refining health models. Embodiments of the invention use machine learning tools to analyze historical telemetry data from a server deployment. The tools output fingerprints, for example, small groupings of specific metrics-plus-behavioral parameters, that uniquely identify and describe past problem events mined from the historical data. Embodiments automatically translate the fingerprints into health models that can be directly applied to monitoring the running system. Fully-automated feedback loops for identifying past problems and giving advance notice as those problems emerge in the future is facilitated without any operator intervention. In some embodiments, a single portion of expert knowledge, for example, Key Performance Indicator (KPI) data, initiates health model generation.

Abstract: A refrigerant compressor arrangement is disclosed, having a compressor which is arranged in a housing and which has a suction connection, the housing being provided with a suction connector which is joined to the suction connection by way of a suction channel. In such an arrangement, it is desirable to increase the opportunity of the compressor to move, that is, to reduce noise, without at the same time having to accept a deterioration in efficiency. To that end, at its housing end the suction channel is in the form of a telescope tube which is capable of being telescoped into the suction connector.
