摘要:
A cloud manager uses streams to monitor state of the cloud. A cloud state streaming policy specifies state data to stream, along with one or more initial operators for processing the streams. An archive mechanism allows archiving the streamed data when specified data in the streams exceeds one or more defined thresholds. A user interface allows adjusting the streaming of cloud state data to focus on data of interest to a user. The cloud manager thus allows a user to determine state of a cloud via the streamed state data.

One or more operators in a flow graph of a streaming application may include one or more triggers that indicate when action needs to be taken for the operator. A streams manager monitors performance of a streaming application and receives a notification when a trigger in an operator fires. In response to a trigger firing, the streams manager determines an appropriate action corresponding to the trigger. When the trigger indicates an adjustment of cloud resources are needed, the streams manager formulates a cloud resource request to a cloud manager. In response, the cloud manager adjusts the cloud resources for the operator to improve performance of the streaming application. A trigger may specify a trigger action for an operator, and may additionally specify a trigger action for one or more other affected operators. The firing of a trigger in one operator can therefore result in adjusting resources to multiple operators.

A streams manager monitors performance of a streaming application, and when the performance needs to be improved, the streams manager automatically requests virtual machines from a cloud manager. The cloud manager provisions one or more virtual machines in a cloud with the specified streams infrastructure and streams application components. The streams manager then modifies the flow graph so one or more portions of the streaming application are hosted by the virtual machines in the cloud. When performance of the streaming application indicates a virtual machine is no longer needed, the virtual machine is maintained and placed in a ready state so it can be quickly used as needed in the future without the overhead of deploying a new virtual machine.

An apparatus and method uses location based authentication of a user accessing a virtual machine (VM) by using the physical location of the virtual machine as a criteria for the authentication. When a user requires a logical partition to run in a known, specified physical location, the user specifies the physical location when the VM is created. The specified physical location is then incorporated into the user authentication process. Users are challenged and must know the physical location in order to be authenticated to the system. When a “disruptive event” in the cloud environment occurs that necessitates moving the VM to another location, the original physical location is stored so the virtualization manager later can automatically relocate the VM back to its original physical location.

A pluggable cloud enablement boot device (PCEBD) is a bootable device that includes all information needed to automatically provision hardware and software to create a computing solution that meets customer requirements. This allows for quickly deploying a computing solution in a manner that eliminates many manual steps that are typically performed today. The PCEBD uses firmware to verify a given platform has sufficient resources to deploy the PCEBD. The computing solution, once provisioned and running, can be modified, and these modifications may be reflected in the definition of the PCEBD. In addition, a computing solution may include multiple resources provisioned from multiple PCEBDs, which can be packaged into a PCEBD that will include other PCEBDs. The result is a way to deploy computing solutions that is much more efficient than the manual methods used in the prior art.

Embodiments of the preset disclosure include a method, a system, and a computer program product for rearranging a set of filters within a data streams environment. The method includes setting a first filter ordering of two or more filter processing elements. The method includes determining a filtering efficiency of the first filter ordering. The determining of the filtering efficiency includes monitoring a runtime, one or more tuples, and an amount of tuples retained after filtering of the first filter ordering. The method includes creating a second filter ordering of the two or more filter processing elements. The method includes comparing the filtering efficiency of the second filter ordering to the first filter ordering. The method includes selecting the second filter ordering in response to comparing the filtering efficiency of the second filter ordering to the filtering efficiency of the first filter ordering.

An appliance migration mechanism (AMM) optimizes migration of a live virtual appliance with virtual objects between cloud environments to minimize temporary connections that use significant cloud resources during the migration. The AMM determines a cost of connections of each virtual object in the virtual appliance and produces an order of migration for the virtual objects. The cost of connections of the virtual objects may be determined by the total number of connections and the maximum number of connections. Alternatively the cost of the connections of the virtual objects for migration could be determined by a weighting the costs of the connections where the weighting may consider loading or other factors on the connection.

A stream application receives a stream of tuples to be processed by a plurality of processing elements. The plurality of processing elements operate on one or more compute nodes. Each processing element has one or more stream operators. Segments of software code are embedded in a tuple of the stream of tuples. The tuple retrieves one or more compute node metrics. The compute node metrics describe one or more resources of a first compute node. The tuple obtains tuple information of one or more tuples of the stream of tuples to be processed by a first stream operator that operates on the one or more resources. The tuple determines a prospective resource disparity related to the first stream operator based on the obtained tuple information and the compute node metrics. The tuple transmits a resource request to the stream application based on the determined prospective resource disparity.

A streams manager monitors performance of a streaming application and determines if operators are underperforming according to a threshold. When the performance needs to be improved, the streams manager automatically modifies the flow graph to offload or reroute a stream of data, or part of a stream of data, to a similar operator to more efficiently utilize streaming resources. Operators are provided with multiple ports to allow the streams manager to send additional streams to the operator.
