Abstract: A node grouping system for grouping a plurality of nodes of a computer system, includes: a processor; a memory operatively coupled to the processor; a node aggregator component comprising instructions stored in the memory and operable to cause the system, under control of the processor, to group the plurality of nodes by: comparing first characteristics of a first node of the plurality of nodes with first grouping criteria of a first group to determine if the first characteristics satisfy the first grouping criteria; grouping the first node with the first group based on a determination that the first characteristics satisfy the first grouping criteria; and storing the grouping within the memory; and an interface component comprising instructions stored in the memory and operable to cause said system, under control of the processor, to display the grouping comprising the first node.

Abstract: A node grouping system for grouping a plurality of nodes of a computer system, said node grouping system comprising: a processor; a memory operatively coupled to said processor; a node aggregator component comprising instructions stored in said memory and operable to cause said system, under control of said processor, to group said plurality of nodes by: comparing first characteristics of a first node of said plurality of nodes with first grouping criteria of a first group to determine if said first characteristics satisfy said first grouping criteria; grouping said first node with said first group based on a determination that said first characteristics satisfy said first grouping criteria; and storing said grouping within said memory; and an interface component comprising instructions stored in said memory and operable to cause said system, under control of said processor, to display said grouping comprising said first node.

Abstract: A program analysis system for evaluating a target program on a target computer system, said program analysis system comprising: a processor; a memory operatively coupled to said processor; a program analyzer component comprising instructions stored in said memory and operable to cause said system, to analyze said target computer system to identify first information characteristics of said target program; an information determiner component comprising instructions stored in said memory and operable to cause said system, to review one or more of information sources external from said target computer system to identify second information characteristics associated with said target program; and an information fuser component comprising instructions stored in said memory and operable to cause said system, to fuse said first information characteristics and said second information characteristics to generate fused information and store information associating said first and second information characteristics within

Abstract: Described embodiments provide for a cloud computing system with cloud services provided by several cloud service providers. Cloud service data is collected from sensors within each cloud service provider's service, and system models are developed based on the collected cloud service data. The user provides configuration data that is related to performance and cost objectives for the cloud computing system. Performance and cost predictions for the cloud computing system are generated based on the system models and the user configuration data; and then processed to provide a set of attributes and parameters for the cloud computing system. The set of attributes and parameters for the cloud computing system are presented to the user for selection. Based on the set of attributes and parameters, the cloud computing system operates by employing selected attributes and parameters from within a set of differing cloud service providers.
