    Abstract: Various examples for performing rule processing for device management data evaluation are described. According to some examples, one or more computing devices can receive new device data from a client device indicative of a current configuration of the client device and identify a change of a device configuration value from a past device configuration value by comparing the new device data to historic device data. The computing devices can send the new device data to a rule evaluation service to identify one or more rules associated with the device configuration value a rule action service to perform an action specified in the rules. The rule action service can determine the action to perform based on the device configuration value.

    Abstract: Event based analytics database synchronization is described. In one example, an event tracking engine can sequence through batches of records in a transactional database that is being synchronized to an analytics database. The event tracking engine can determine a last version attribute associated with the batch, and query the transactional database to identify any records for the batch having a more recent version attribute than the last version attribute. When any records in the transactional database having a more recent version attribute are identified, the event tracking engine finds the data values in the record are different than those in the analytics database. The data values can be normalized, for example, before being forwarded to an analytics system for incorporation into the a analytics database. Over time, changes in the transactional database are identified and populated or mirrored in the analytics database.

    Abstract: Trigger based analytics database synchronization is described. In one example case, a trigger is invoked based on an operation issued for a record in a transactional database. According to the trigger, one or more data values for synchronization from the transactional database to an analytics database are determined. A message including the data values is formed and added to a message queue through a message infrastructure service including a message broker. In turn, the values from the message are stored in a suitable memory space, such as a staging table, for forwarding to an analytics computing system. Using the trigger and the message infrastructure service, execution of the transactional database operation can be detached in execution from the addition of the value to the staging table and synchronization with the analytics computing system.

    Abstract: A method for a parallel execution of services of a serial service chain on packets using multicast-based service insertion is disclosed. In an embodiment, the method comprises identifying a plurality of services to be applied to packets of a data flow and determining a plurality of service machines that are configured to provide the plurality of services for the data flow. The plurality of service machines is grouped to a plurality of multicast groups; wherein multicast groups in the plurality of multicast groups are sequentially ordered from a first multicast group that includes a largest count of service machines to a last multicast group that includes a smallest count of service machines. Upon detecting a packet of the data flow, the is stored in memory, and multicast to the first multicast group of the plurality of multicast groups to cause applying, in parallel, services of service machines included in the first multicast group to the packet. Once a plurality of responses is received from service machines that belong to the first multicast group, the plurality of responses is used to determine whether service processing of the packet is completed. In response to determining that service processing of the packet is completed, the packet is disposed according the plurality of responses and without multicasting the packet to any other multicast group of the plurality of multicast groups.

    Abstract: A method for a parallel execution of services, of a serial service chain, on packets using multicast-based service insertion is disclosed. In an embodiment, a method comprises detecting a packet of a data flow and storing the packet in memory. From a plurality of multicast groups, a first multicast group is identified. The first multicast group includes a plurality of service machines configured to provide a plurality of services to the data flow. The first multicast group includes all services machines of the plurality of service machines. The packet is multicast to the first multicast group of the plurality of multicast groups to cause applying, in parallel, services of service machines included in the first multicast group. Upon receiving a plurality of responses from service machines of the first multicast group, the plurality of responses is analyzed to determine whether the plurality of responses includes a modify-response. In response to determining that the plurality of responses does not include any modify-response, the plurality of responses is analyzed to determine whether the plurality of responses includes a drop-response. In response to determining that the plurality of responses does not include any drop-response, the packet is forwarded toward its destination without multicasting the packet to any other multicast group of the plurality of multicast groups.
