The disclosure provides Internet of Things (IoT) systems organized as tree hierarchies in which rule processing can occur at each level of the tree hierarchies. In the IoT system according to one embodiment, formulas are defined and centrally managed at a cloud hub that is a root of a tree hierarchy. Each formula defined at the cloud hub is further percolated down to a hub, which may be the cloud hub itself or a local hub, in the tree hierarchy that is logically closest to devices specified in the formula. Each of the cloud and local hubs in the IoT system may utilize the same core IoT platform image, providing ease of management. In addition, formulas may be defined with basic stimuli and responses, as well as with higher-order stimuli and responses that combine one or more other stimuli and responses, respectively.

In an embodiment, a method for monitoring elements of a distributed computing system is disclosed. In the embodiment, the method involves evaluating a metric event from a monitored element based on at least one of tags and conditions of the monitored element by applying declared group functions corresponding to declared groups over the metric event and at least one of admitting the monitored element into membership of a declared group, evicting the monitored element from membership of a declared group, and maintaining membership of the monitored element in a declared group based on the evaluation of the metric event.

System and computer-implemented method for enabling end-user license enforcement of an application in a hybrid cloud system use data associated with at least one component of a public cloud computing environment of the hybrid cloud system to detect an environment-changing event involving at least one processing entity in the hybrid cloud system. Once the environment-changing event is detected, one or more operating environment identifiers are injected into the processing entity. The injected operating environment identifiers can then be accessed by an application in the processing entity to perform an end-user license check for enforcement.

An example method of monitoring elements in a cloud computing system includes partitioning an address space of a hierarchy of service elements into a plurality of address subspaces managed by a respective plurality of processing nodes. The method further includes receiving time series data from a service element, routing the time series data to a first processing node based on an address of the service element within the hierarchy, and processing the time series data at the first processing node to update metric data maintained for the service element. The method further includes routing the time series data to a second processing node based on an address of a parent service element above the service element in the hierarchy, and processing the time series data at the second processing node to update metric data maintained for the parent service element.

Monitoring element hierarchies in a cloud computing system

A cloud computing system includes services that provide virtual cloud computing resources. The service publishes service events that are transformed into periodic rating data as per centralized, pluggable, service-specific business rules. The cloud computing system includes a metering service that reduces network traffic for billing using a carry-forward mechanism that remembers a last-known rating state. Anomalies in the last-known state, such as, from lost or duplicate service events, can be detected via a reconciliation protocol between the metering service and cloud computing services.
