Abstract: Methods, apparatuses, and computer program products for visualizing migration of a resource of a distributed computing environment are provided. Embodiments include displaying, within a graphical user interface (GUI), one or more graphical resource representations. Each graphical resource representation represents a resource of a distributed computing environment. Each graphical resource representation is displayed in a particular location within the GUI according to a location of the resource within the distributed computing environment. Embodiments also include displaying, within the GUI, a first graphical migration representation. The first graphical migration representation represents a first transfer operation of a first resource of the distributed computing environment.

Abstract: Methods, apparatuses, and computer program products for managing virtual machine images in a distributed computing environment are provided. Embodiments includes a management system recording dependencies between the virtual machine images in the image service repository and dependencies between the deployed virtual machines in the compute service and the virtual machine images in the image service repository. Based on the recorded dependencies between the virtual machine images and the dependencies between the deployed virtual machines and the virtual machine images, the management system identifies a virtual machine image that has no deployed virtual machine dependent upon it. Embodiments also include the management system deleting, by the management system, the identified virtual machine image from the image service repository.

Abstract: Methods, apparatuses, and computer program product for distributed debugging of an application in a distributed computing environment are provided. Embodiments include a first debug module on a first host receiving a set breakpoint message from a management debug module of a management system. In response to receiving the set breakpoint message, the first debug module sets a breakpoint for executing a first service on the first host, for the application. Upon hitting the breakpoint while executing the first service for the application, the first debug module sends a breakpoint condition of the first service to the management debug module. In response to receiving the breakpoint condition, the management debug module sends to a second debug module of a second host, an instruction to pause execution of the second service of the second host.

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. In response, the cloud manager provisions one or more virtual machines in a cloud. The streams manager builds a permutation of a flow graph for the streaming application using the virtual machine(s), runs the permutation in parallel with the corresponding portion of the flow graph, and compares the performance of the original portion of the flow graph to the performance of the permutation. When the performance of the permutation exceeds the performance of the original part of the flow graph, the streams manager modifies the flow graph so the permutation replaces the original part of the flow graph. In this manner a streaming application can dynamically evolve to increase its performance as needed.

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 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.

Abstract: Resizing resource allocation in a computing environment, including: displaying, within a graphical user interface, a graphical element representing allocation parameters, the allocation parameters indicating a user's current allocation of one or more resources of the computing environment; displaying, within the graphical user interface, a graphical element representing utilization parameters, the utilization parameters indicating the user's current utilization of the one or more resources of the computing environment; receiving, within the graphical user interface, user input to manipulate the graphical element representing the allocation parameters; and changing, based on the user input received within the graphical user interface, the allocation parameters.

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.

Abstract: Visually depicting resource utilization in a cloud computing environment, including: identifying a plurality of resources available to a user in the cloud computing environment; identifying resource utilization values for each of the identified resources; assigning each resource to one or more axes of a coordinate system; mapping the resource utilization values for each of the identified resources on the coordinate system; and displaying the resource utilization values for each of the identified resources on the coordinate system

Abstract: Visually depicting cloud resource utilization during execution of an application, the application using multiple cloud resources deployed on multiple cloud hosts, including: displaying, by a resource monitoring module in a graphical user interface, a visual depiction of resource utilization of the multiple cloud resources during execution of the application; receiving, from a user through the graphical user interface displaying the visual depiction of resource utilization of the multiple cloud resources, a resource utilization threshold for each of the multiple cloud resources; determining, by the resource monitoring module, whether one or more of the resource utilization thresholds have been reached; and responsive to determining that one or more of the resource utilization thresholds have been reached, executing a predetermined action.
