Abstract

Various embodiments of systems and methods for application scope adjustment based on resource consumption are described herein. A load parameter of a data center is measured. A request is received at the data center. An implementation variant to process the request is selected based on the measured load parameter and a threshold value of the load parameter. The implementation variant comprises a standard process for processing the received request and an alternative process for processing the received request that reduces the impact on the load parameter compared to the standard process. The received request is processed using the selected implementation variant.

Claims

1. An article of manufacture including a non-transitory computer readable storage medium to tangibly store instructions, which when executed by a computer, cause the computer to:

measure a load parameter of a data center;

receive a request at the data center;

select an implementation variant to process the request based on the measured load parameter and a threshold value of the load parameter, wherein the implementation variant comprises a standard process for processing the received request and an alternative process for processing the received request that reduces the impact on the load parameter compared to the standard process, wherein the standard process uses primary data for processing the request and the alternative process uses secondary data including derived data and a portion of the primary data; and

process the received request using the selected implementation variant;

wherein the standard process is selected when the measured load parameter is below the threshold load parameter and the alternative process is selected when the measured load parameter is above the threshold load parameter.

2. The article of manufacture of claim 1, wherein the load parameter comprises at least one of processor usage, memory usage, network bandwidth, and input/output usage.

3. The article of manufacture of claim 1, wherein the instructions to select the alternative process, comprises instructions, which when executed by a computer, cause the computer to:

when there are a plurality of alternative processes, select one of the plurality of alternative processes with a relatively lower measured load parameter.

4. The article of manufacture of claim 1, wherein the instructions to select the implementation variant further comprises instructions, which when executed by a computer, cause the computer to:

select the implementation variant to process the request based on resources required to process the received request, the measured load parameter, and the threshold value of the load parameter.

5. The article of manufacture of claim 4, wherein the instructions to select the implementation variant, comprises instructions, which when executed by a computer, cause the computer to:

select the alternative process when the sum of the resources required to process the request and the measured load parameter is greater than or equal to the threshold load parameter.

6. The article of manufacture of claim 4, wherein the instructions to select the implementation variant, comprises instructions, which when executed by a computer, cause the computer to:

select the standard process when the sum of the resources required to process the request and the measured load parameter is less than the threshold load parameter.

7. The article of manufacture of claim 4, wherein the implementation variant further comprises request-rejection variant and the instructions to select the implementation variant, comprises instructions, which when executed by a computer, cause the computer to:

select the request-rejection variant when there is no alternative process for a particular request.

8. A computer-implemented method for adjusting application scope based on resource usage, the method comprising:

measuring a load parameter of a data center;

receiving a request at the data center;

selecting an implementation variant to process the request based on the measured load parameter and a threshold value of the load parameter, wherein the implementation variant comprises a standard process for processing the received request and an alternative process for processing the received request that reduces the impact on the load parameter compared to the standard process, wherein the standard process uses primary data for processing the request and the alternative process uses secondary data including derived data and a portion of the primary data; and

processing the received request using the selected implementation variant;

wherein the standard process is selected when the measured load parameter is below the threshold load parameter and the alternative process is selected when the measured load parameter is above the threshold load parameter.

9. The method of claim 8, wherein the load parameter comprises at least one of processor usage, memory usage, network bandwidth, and input/output usage.

10. The method of claim 8, wherein selecting the alternative process, comprises:

when there are a plurality of alternative processes and load parameters, selecting one of the plurality of alternative processes with a relatively lower measured load parameter.

11. The method of claim 8, wherein selecting the implementation variant further comprises:

selecting the implementation variant to process the request based on resources required to process the received request, the measured load parameter, and the threshold value of the load parameter.

12. The method of claim 11, wherein selecting the implementation variant comprises:

selecting the alternative process when the sum of the resources required to process the request and the measured load parameter is greater than or equal to the threshold load parameter.

13. The method of claim 11, wherein selecting the implementation variant comprises:

selecting the standard process when the sum of the resources required to process the request and the measured load parameter is less than the threshold load parameter.

14. The method of claim 11, wherein the implementation variant further comprises request-rejection variant and selecting the implementation variant, comprises:

selecting the request-rejection variant when there is no alternative process for a particular request.

15. A computer system for adjusting application scope based on resource usage, comprising:

a computer memory to store program code; and

a processor to execute the program code to;

measure a load parameter of a data center;

receive a request at the data center;

select an implementation variant to process the request based on the measured load parameter and a threshold value of the load parameter, wherein the implementation variant comprises a standard process for processing the received request and an alternative process for processing the received request that reduces the impact on the load parameter compared to the standard process, wherein the standard process uses primary data for processing the request and the alternative process uses secondary data including derived data and a portion of the primary data; and

process the received request using the selected implementation variant;

wherein the standard process is selected when the measured load parameter is below the threshold load parameter and the alternative process is selected when the measured load parameter is above the threshold load parameter.

16. The system of claim 15, wherein the load parameter comprises at least one of processor usage, memory usage, network bandwidth, and input/output usage.

17. The system of claim 15, wherein the program code to select the alternative process, comprises program code to:
