In a decoupled messaging system, a producer device sends produced messages to a message fabric. The message fabric either stores the received message in designated queues, from which consumer devices may retrieve the messages, or broadcasts the messages to consumer devices that subscribe to topics assigned to the messages. A message consumption orchestrator service gathers capabilities information for the message producer, the message fabric, and the message consumer, and configures resources allocated for the message consumer to more fully optimize message throughput. Further, the message consumption orchestrator identifies patterns in changes of the rate of produced messages, i.e., through analysis of historical data and/or received information. The message consumption orchestrator configures resources for the message consumer to account for predicted need based on the identified patterns.

An improved system and method for updating software is described. The system, upon detecting one or more changes within the set of eligibility attribute values associated with the one or more particular components of previously-provided software, selects a replacement component. The component is selected based on one or more changed eligibility attribute values within the set of eligibility attribute values, and the metadata of the user device. Using the replacement component, the replacement software is constructed and sent to the user device.

Dynamic software assembly

A mechanism is provided for controlling a process on a computing node. In one implementation, a determination is made as to whether the participation status of a computing node has changed. The participation status may, for example, be active, in which case the computing node is participating in the processing of requests from a request handler, or it may be passive, in which case the computing node is not participating in the processing of requests from the request handler. In response to a determination that the participation status of the computing node has changed from a current status to a new status, one or more processes on the computing node may be caused to begin or halt processing, in accordance with the new status. For example, if the current status is passive and the new status is active, a process on the computing node may be caused to begin processing. On the other hand, if the current status is active and the new status is passive, the process on the computing node may be caused to halt processing. Doing so helps to ensure that a process (such as a self-initiated process) executing on a passive node will not perform any processing that may lead to incorrect or inconsistent results, or even worse, to system corruption or failure.

Techniques are described for identifying unhealthy nodes in a multi-node system. One or more parameters of each node is monitored, then compared with the values for the same parameter running on other nodes in the multi-node system. Based on the comparison, a determination is made whether a node is healthy. If the multi-node system comprises one or more nodes with differing capabilities, an adjustment is performed to account for the differing capabilities of each respective node. Further provided are methods of taking remedial action upon a determination that a node is unhealthy. A tuner is used to modify values of health parameters until the node is performing similarly to its peers.

Dynamic service fault detection and recovery using peer services

A method for selecting a tag for a content item includes obtaining a first content item; obtaining data associated with a first user; based on the data associated with the first user, selecting a first tag for the first content item; and generating a second content item comprising (a) at least a portion of the first content item and (b) the first tag.

System generated context-based tagging of content items

An automated resource resolver system receives a client request for a learning resource. The system selects a format for a target resource, to be delivered to the client device, based on user information and context information for the client device. Thus, the selected format will be accessible by the client device, utilizing the capabilities of the device, and will be the best-fit format for the user. After the system selects the format, the system determines whether the target resource stored at a resource repository is in the selected format. If not, then the system selects an instance of the target resource, not in the selected format, to convert to the selected format. The system converts the selected resource instance to produce an instance of the target resource that is in the selected format. The system makes the target learning resource, in the selected format, available to the client device.

An improved system and method for providing software is described. The system, upon receiving a software request from a user device, obtains metadata about the user device. Based on the metadata and the software requested, a template of the software is obtained. The template specifies a list of categories, where each category is associated with component(s) in a component database. Based on the metadata and eligibility attributes of the respective components, one component from each category is selected for inclusion in the software. From the selected components and the template, the requested software is constructed and sent to the user device. In some embodiments, for popular user devices, a previously stored selection of components can be accessed. In some embodiments, an updated version of the software is provided if the metadata of the user device changes or if there is a change in the available components or software templates.
