Application performance evaluation with dual model

A computer system for predicting optimal configurations for deploying a given resource in a computing environment, the computer system comprising:

• a memory;
• and
• one or more processors in communication with the memory, wherein the computer system is configured to perform a method, said method comprising:
• obtaining, by the one or more processors, one or more factors relevant to the given resource;
• determining, by the one or more processors, relationships between the one or more factors;
• based on parameters comprising the relationships, identifying, by the one or more processors, from a search space, one or more resources configurations for at least one resource and one or more workload configurations for at least one workload in the computing environment;
• executing, by the one or more processors, based on a pre-defined policy, a test, wherein the test executes a workload configured according to a workload configuration of the one or more workload configurations for the at least one workload in a system under a test instance configured according to a resource configuration of the one or more resource configurations for the at least one resource;
• obtaining, by the one or more processors, performance measurements for the test in the system under test instance;
• and
• utilizing, by the one or more processors, the performance measurements to update a known data set.

A computer program product for predicting optimal configurations for deploying a given resource in a computing environment, the computer program product comprising:

• one or more computer readable storage media and program instructions collectively stored on the one or more computer readable storage media readable by at least one processing circuit to:
• obtain, by the one or more processors, one or more factors relevant to the given resource;
• determine, by the one or more processors, relationships between the one or more factors;
• based on parameters comprising the relationships, identify, by the one or more processors, from a search space, one or more resources configurations for at least one resource and one or more workload configurations for at least one workload in the computing environment;
• execute, by the one or more processors, based on a pre-defined policy, a test, wherein the test executes a workload configured according to a workload configuration of the one or more workload configurations for the at least one workload in a system under a test instance configured according to a resource configuration of the one or more resource configurations for the at least one resource;
• obtain, by the one or more processors, performance measurements for the test in the system under test instance;
• and
• utilize, by the one or more processors, the performance measurements to update a known data set.
