VERFAHREN UND VORRICHTUNG ZUR ERFORSCHUNG EINER MARGE ZUR RESSOURCENOPTIMIERUNG IN EINER ANWENDUNGSKETTE

摘要

The invention relates to a resource optimization margin search method of an IT infrastructure, said IT infrastructure hosting an application chain using a plurality of resources, said method comprising the following steps:Execution (200) of a set of requests, said execution of the set of requests simulating the operation of the application chain,- Analyzing (300) the results of the set of requests, said analysis comprising a measurement (310) of quality of service parameter values in response to the execution of the set of requests and a comparison (320) of the values measured quality of service parameters to predetermined threshold values of quality of service parameters,- Analysis (400) of the use of the resources, said analysis comprising a measurement (410) of resource utilization values in response to the execution of the set of requests and a comparison (420) of the measured values of using resources at predetermined minimum threshold values for resource use,- Identification (500) of a resource optimization margin, said identification comprising the identification of an underutilized resource, said underutilized resource being a resource whose measured value of resource use is less than the predetermined maximum threshold value of use of said resource while the measured values of quality of service parameters are in adequacy with the values of the predetermined thresholds of quality of service parameters.
