Method for managing computational resources of a data center

A data center comprising:

• one or more managing entities and a decision making entity (DME), the one or more managing entities being adapted to assign one or more computational resources of the data center to one or more physical and/or virtual functions by one or more management decisions (MD) of the DME, the DME being adapted to make the MD based on collected performance information of the resources, the collected performance information being analysed considering one or more predefined performance parameters, a single performance metric (SPM) being is-computed representing performance and efficiency of the DME using a result of the analysis, and wherein the DME is adapted to use the SPM for making the MD.

A computing entity adapted to:

• make one or more management decisions (MD) for assigning one or more computational resources of a data center to one or more physical and/or virtual functions, the MD being based on collected performance information of the computational resources being analysed and compared to predefined performance parameters;
• and
• use a single performance metric (SPM) representing performance and efficiency of the computing entity to make the MD.
