A method to mitigate attack by an upstream service provider using cloud mitigation services. An edge detection device, which located at the subscriber's network edge, is able to communicate information via status messages about attacks to an upstream service provider. The service provider is then able to mitigate attacks based on the status messages. There is a feedback loop whereby the amount of dropped traffic by the service provider is added to the network traffic to keep the mitigation request open and prevent flapping. Likewise, the detection device includes time-to-engage and time-to-disengage timers to further prevent flapping.

Embodiments are directed to preventing flapping when auto-scaling cloud resources. In one scenario, a computer system accesses information specifying a target operational metric that is to be maintained on a plurality of cloud resources. The computer system determines a current measured value for the target operational metric for at least some of the cloud resources. The computer system further calculates a scaling factor based on the target operational metric and the current measured value, where the scaling factor represents an amount of variance between the target operational metric and the current measured value. The computer system also calculates a delta value representing a modified quantity of cloud resources modified by the calculated scaling factor and determines whether a scaling action is to occur based on the calculated delta value.

A strap assembly device is used to maintain engagement between the strap and the strap anchor point. The strap assembly device works by creating a loop to prevent the fastening hook on the strap from slipping. The strap assembly device is looped through a strap anchor point and the fastening hook is engaged to the anchor point. A portion of the strap extends beyond the fastening hook through the anchor point. The strap creates a loop by using a fastening system. The fastening system is generated by a male and female portion being joined. Either the male or female portion of the fastening system is located on the medial portion of the strap (portion before the hook). The other portion of the fastening system, male or female, is located on the lateral portion of the strap (portion extending beyond the hook). Once the fastening hook is engaged with the strap anchor point on the vehicle, the male and female portions of the fastening systems are joined. This union of the male and female fastening systems disallows the fastening hook from becoming disengaged from the strap anchor point.
