USING CLOUD RESOURCES TO IMPROVE PERFORMANCE OF A STREAMING APPLICATION
First Claim
Patent Images
1. An apparatus comprising:
- at least one processor;
a memory coupled to the at least one processor;
a streaming application residing in the memory and executed by the at least one processor, the streaming application comprising a flow graph that includes a plurality of operators that process a plurality of data tuples; and
a streams manager residing in the memory and executed by the at least one processor, the streams manager monitoring performance of the streaming application, and when performance of the streaming application needs to be improved, the streams manager requests a cloud manager to provision at least one virtual machine with logic to implement at least one of the plurality of operators, and when the cloud manager provisions the at least one virtual machine, the streams manager modifies the flow graph to include the at least one virtual machine in the flow graph of the streaming application.

Abstract
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 streams manager specifies to the cloud manager streams infrastructure and one or more streams application components for the virtual machines. 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.
