Abstract

A method includes monitoring a load of a management target system on which a plurality of virtual machines are executed, cancelling an instruction to activate a virtual machine according to the monitored load and a status of the virtual machine for which the instruction to activate the virtual machine is previously given to the system and which is still under the activation process; and issuing an instruction to the system to stop the virtual machine which is still under an activation process according to the monitored load and the status of the virtual machine.

Claims

1. A method comprising:

monitoring, by a processor, a load of a management target system on which a plurality of virtual machines are executed;

cancelling, by the processor, an instruction to activate a virtual machine according to the monitored load and a status of the virtual machine for which the instruction to activate the virtual machine is previously given to the system and which is still under the activation process; and

issuing, by the processor, an instruction to the system to stop the virtual machine which is still under an activation process according to the monitored load and the status of the virtual machine.

2. The method of claim 1, further comprising:

issuing, by the processor, an instruction to the system to stop the virtual machine under the activation process when an instruction to decrease a resource of the management target system is given and the virtual machine under the activation process in the system is present; and

issuing, by the processor, an instruction to the system to stop the virtual machine which is running in the system when the instruction to decrease the resource of the management target system is given and the virtual machine under the activation process is not present.

3. The method of claim 2, further comprising:

issuing, by the processor, an instruction to the system to stop a virtual machine of which an activation start time is later when the instruction to decrease the resource of the management target system is given and a plurality of virtual machines under the activation process are present.

4. The method of claim 1, further comprising:

issuing, by the processor, an instruction to the system to perform scale-out of a virtual machine when a change amount of the load at a time of increasing the load exceeds a first threshold value; and

issuing, by the processor, an instruction to the system to perform scale-in of the virtual machine when a change amount of the load at a time of decreasing the load exceeds a second threshold value.

5. The method of claim 4, further comprising:

when giving the instruction of the scale-out or the scale-in,

calculating, by the processor, a sum of a first difference value obtained by multiplying a difference between a current actual measurement load and a target load by a first coefficient and a second difference value obtained by multiplying a difference between the current actual measurement load and an actual measurement load before a predetermined time by a second coefficient; and

setting, by the processor, a value of a positive number as the number of virtual machines to be subjected to the scale-out when the calculated sum is the positive number and setting a value of a negative number as the number of virtual machine to be subjected to the scale-in when the calculated sum is the negative number.

6. An apparatus comprising:

a memory; and

a processor coupled to the memory and configured to execute a process comprising;

monitoring a load of a management target system on which a plurality of virtual machines are executed;

cancelling an instruction to activate a virtual machine according to the monitored load and a status of the virtual machine for which the instruction to activate the virtual machine is previously given to the system and which is still under the activation process; and

issuing an instruction to the system to stop the virtual machine which is still under an activation process according to the monitored load and the status of the virtual machine.

7. The apparatus according to claim 6, wherein the process further comprising:

issuing an instruction to the system to stop the virtual machine under the activation process when an instruction to decrease a resource of the management target system is given and the virtual machine under the activation process in the system is present; and

issuing an instruction to the system to stop the virtual machine which is running in the system when the instruction to decrease the resource of the management target system is given and the virtual machine under the activation process is not present.

8. The apparatus according to claim 7, wherein the process further comprising:

issuing an instruction to the system to stop a virtual machine of which an activation start time is later when the instruction to decrease the resource of the management target system is given and a plurality of virtual machines under the activation process are present.

9. The apparatus according to claim 6, wherein the process further comprising:

issuing an instruction to the system to perform scale-out of a virtual machine when a change amount of the load at a time of increasing the load exceeds a first threshold value; and

issuing an instruction to the system to perform scale-in of the virtual machine when a change amount of the load at a time of decreasing the load exceeds a second threshold value.

10. The apparatus according to claim 9, wherein the process further comprising:

when giving the instruction of the scale-out or the scale-in,

calculating a sum of a first difference value obtained by multiplying a difference between a current actual measurement load and a target load by a first coefficient and a second difference value obtained by multiplying a difference between the current actual measurement load and an actual measurement load before a predetermined time by a second coefficient; and

setting a value of a positive number as the number of virtual machines to be subjected to the scale-out when the calculated sum is the positive number and setting a value of a negative number as the number of virtual machine to be subjected to the scale-in when the calculated sum is the negative number.

11. A non-transitory computer-readable medium storing therein a program that causes the computer to execute a process, the process comprising:

monitoring a load of a management target system on which a plurality of virtual machines are executed;

cancelling an instruction to activate a virtual machine according to the monitored load and a status of the virtual machine for which the instruction to activate the virtual machine is previously given to the system and which is still under the activation process; and
