Abstract: Systems and methods are provided for dynamically configuring an IoT communications system. The IoT communications system receives a client message from an IoT device. The client message includes an endpoint designation (such as by specifying an endpoint in the Server Name Indication (SNI) field of the TLS client hello message). The IoT communications system determines whether the endpoint is associated with a custom or default processing logic and/or settings. Either custom or default processing logic is executed or custom or default settings are applied.

Abstract: A message broker of a publish-subscribe messaging system (e.g., using the MQTT protocol or other publish-subscribe protocol) detects a life-cycle event for topic subscription and notifies a publisher of the life-cycle event. The message broker may detect a transition in a number of subscribers to a topic from zero subscribers to one or more subscribers or from one or more subscribers to zero subscribers. In response, the message broker provides an indication to the publisher that the number of subscribers to the topic has transitioned from zero to one or more (or from one or more to zero). This causes the publisher to begin publishing messages on the publisher's topic (or to stop publishing messages on the publisher's topic).

Abstract: A technology is described for modifying a message frequency of a device. In one example, a network connection is identified between a device and a service provider environment. A message frequency is set for which to send reachability messages between the device and the service provider environment to maintain the network connection. The reachability messages may be sent between the device and the service provider environment at the message frequency. After testing whether the networking connection is maintained at the message frequency, the message frequency may be modified to a modified message frequency.

Abstract: This document describes techniques for activating multiple interruptible resource instances on servers of a service provider environment. In an example embodiment, a system can activate multiple interruptible resource instances on behalf of a given customer based on a comparison of a bid cost value from the customer to the current, but variable cost value of the interruptible resource instances. The customer also can specify a value indicative of the number of interruptible resource instances to be activated on behalf of the customer based on the bid cost value.
