Dynamically responding to demand for server computing resources

A system, comprising:

• a processor and memory;
• a component configured to monitor performance of each given computing system of multiple computing systems in a data center, wherein monitoring performance includes gathering a utilization of a central processing unit of the given computing system determined as a function of a total number of idle compute cycles of the central processing unit in a given time period, and gathering a latency associated with an input/output (IO) operation;
• a component configured to identify a particular computing system of the multiple computing systems using the monitored performance by determining a current state of execution of the particular computing system as a function of the gathered utilization of the central processing unit and the gathered latency associated with the IO operation, the particular computing system being identified for an allocation of additional computing power;
• a component configured to determine availability of an additional power supply to allocate to the particular computing system, the additional power supply being a function of the additional computing power;
• a component configured to determine availability of a capacity on a power distribution line connected to the particular computing system to provide the additional power supply to the particular computing system by predicting a peak power load of the power distribution line as a function of a current power load and historical power usage patterns, and determining a difference between the predicted peak power load and a maximum power threshold of the power distribution line;
• and
• a component configured to allocate the additional computing power to the particular computing system as a function of the determined availability of the additional power supply and the determined availability of the capacity on the power distribution line.

A non-transitory computer readable storage memory storing computer executable instructions, comprising:

• instructions for monitoring performance of each given computing system of multiple computing systems in a data center, wherein the instructions for monitoring performance include instructions for gathering a utilization of a central processing unit of the given computing system determined as a function of a total number of idle compute cycles of the central processing unit in a given time period, and instructions for gathering a latency associated with an input/output (IO) operation;
• instructions for identifying a particular computing system of the multiple computing systems using the monitored performance by determining a current state of execution of the particular computing system as a function of the gathered utilization of the central processing unit and the gathered latency associated with the IO operation, the particular computing system being identified for an allocation of additional computing power;
• instructions for determining availability of an additional power supply to allocate to the particular computing system, the additional power supply being a function of the additional computing power;
• instructions for determining availability of a capacity on a power distribution line connected to the particular computing system to provide the additional power supply to the particular computing system by predicting a peak power load of the power distribution line as a function of a current power load and historical power usage patterns, and determining a difference between the predicted peak power load and a maximum power threshold of the power distribution line;
