Systems and methods are provided to process an event stream using nodes arranged as a cluster in which the nodes are in a leader-follower relationship with one node being the leader at any given time. Tracking of node membership and leadership status can be conducted in a manager node for a variety of applications. Each node of the cluster can register in the manager node and can receive the same set of event streams as the other nodes of the cluster. The leader node can process an event of an event stream with the follower nodes tracking the processing by the leader node, where the leader node can publish the processed event. Leadership can be changed from the leader node to another node of the cluster based on a performance criterion of the leader node. Additional systems and methods can be implemented in a variety of applications.

Event stream processing

Various embodiments include devices and methods structured to provide an intelligent event processing offload, which can facilitate an efficient, geo-distributed tiered scalable event streaming and processing interconnect through an embedded adapter interconnect. Event streams received in a data handler from one or more networks can be separated into partitions. The loading of the event streams into the partitions can be tracked to balance the loading by controlling the number of partitions used. Packets of each partition can be sent to a respective reactive router that resides in a controlling application for further processing. Additional devices, systems, and methods can be implemented in a variety of applications.

Intelligent event streaming

Techniques are provided to derive a virtual machine workload cost for a data center. At a network management appliance that is in communication with network resources and computing resources used by a plurality of virtual machines executed by the computing resources for providing one or more services, usage metrics are collected from network components of the network resources operating with respect to traffic that passes through the network resources as a result of the plurality of virtual machines executed by the computing resources. The virtual machine workload cost is computed from the usage metrics.

Data center resource usage and cost determination

Systems, methods, and other embodiments associated with importing proximity data are provided. Device identification information and device location information associated with a device are received from a data source. An estimated proximity of the device to one or more network zones is determined based at least in part on the device location information. A device identifier and the estimated proximity of the device are stored in a proximity database that stores proximity data for devices relative to one or more network zones.
