Abstract

Methods and apparatus to reclaim resources in virtual computing environments are described. An example method includes determining, with a processor, if a characteristic of a virtual machine meets a threshold indicating that the virtual machine is inactive, in response to determining that the characteristic meets the threshold, determining, with the processor, if a notification period has expired, and if the notification period has expired, de-provisioning, with the processor, the virtual machine to return computing resources assigned to the virtual machine to a cloud.

Claims

1. A method comprising:

determining, by executing an instruction with a processor, if a characteristic of a virtual machine meets a threshold indicating that the virtual machine is inactive;

in response to determining that the characteristic meets the threshold;

transmitting, by executing an instruction with the processor, a notification of inactivity to an administrator of the virtual machine,

determining, by executing an instruction with the processor, if a notification period based on the notification has expired, and

determining, by executing an instruction with the processor, whether the virtual machine is tagged with an indication that the virtual machine is at least one of a replica of an active virtual machine or a backup of an active virtual machine;

if the notification period has expired and the virtual machine is not tagged with the indication, de-provisioning, by executing an instruction with the processor, the virtual machine to return computing resources assigned to the virtual machine to a computing cloud; and

not de-provisioning the virtual machine if the virtual machine is tagged with the indication.

2. A method as defined in claim 1, further including initiating the notification period in response to transmitting the notification.

3. A method as defined in claim 1, wherein the notification period indicates an amount of time to wait before de-provisioning the computing resources after transmitting the notification.

4. A method as defined in claim 1, further including archiving the virtual machine when the virtual machine is de-provisioned.

5. A method as defined in claim 1, wherein the threshold indicates a level of inactivity for the virtual machine.

6. A method as defined in claim 1, wherein the characteristic includes at least one of a last time that the virtual machine was powered on, a last time that the virtual machine was remotely accessed, or an amount of computing resources consumed by the virtual machine.

7. An apparatus comprising:

a notifier to;

transmit a notification of inactivity to an administrator of a virtual machine, and

determine if a notification period based on the notification has expired; and

a resource reclaimer to;

determine if a characteristic of the virtual machine meets a threshold indicating that the virtual machine is inactive,

determine whether the virtual machine is tagged with an indication that the virtual machine is at least one of a replica of an active virtual machine or a backup of an active virtual machine,

in response to determining that the characteristic meets the threshold, the virtual machine is not tagged with the indication, and the notifier determining that the notification period based on the notification has expired, de-provision the virtual machine; and

not de-provision the virtual machine if the virtual machine is tagged with the indication, at least one of the notifier or the resource reclaimer implemented by a processor.

8. An apparatus as defined in claim 7, wherein the resource reclaimer is to return computing resources assigned to the de-provisioned virtual machine to a computing cloud.

9. An apparatus as defined in claim 7, further including a user interface to receive an instruction to perform resource reclamation.

10. An apparatus as defined in claim 7, wherein the notifier is to:

determine that the notification of inactivity has not been sent; and

in response to determining that the notification has not been sent;

transmit the notification to the administrator of the virtual machine, and

initiate the notification period.

11. An apparatus as defined in claim 7, wherein the notification period indicates an amount of time to wait before de-provisioning the computing resources after transmitting a notification.

12. An apparatus as defined in claim 7, further including an archiver to archive the virtual machine when the virtual machine is de-provisioned.

13. An apparatus as defined in claim 7, wherein the threshold indicates a level of inactivity for the virtual machine.

14. An apparatus as defined in claim 7, wherein the characteristic includes at least one of a last time that the virtual machine was powered on, a last time that the virtual machine was remotely accessed, or an amount of the computing resources consumed by the virtual machine.

15. A tangible computer readable storage medium including instructions that, when executed, cause a processor to at least:

determine if a characteristic of a virtual machine meets a threshold indicating that the virtual machine is inactive;

in response to determining that the characteristic meets the threshold;

transmit a notification of inactivity to an administrator of the virtual machine,

determine if a notification period based on the notification has expired,

determine whether the virtual machine is tagged with an indication that the virtual machine is at least one of a replica of an active virtual machine or a backup of an active virtual machine; and

if the notification period has expired and the virtual machine is not tagged with the indication, de-provision the virtual machine to return computing resources assigned to the virtual machine to a computing cloud; and

not de-provision the virtual machine if the virtual machine is tagged with the indication.

16. A tangible computer readable storage medium as defined in claim 15, wherein the instructions, when executed, cause the processor to initiate the notification period.

17. A tangible computer readable storage medium as defined in claim 15, wherein the notification period indicates an amount of time to wait before de-provisioning the computing resources after transmitting the notification.

18. A tangible computer readable storage medium as defined in claim 15, wherein the instructions, when executed, cause the processor to archive the virtual machine when the virtual machine is de-provisioned.

19. A tangible computer readable storage medium as defined in claim 15, wherein the threshold indicates a level of inactivity for the virtual machine.

20. A tangible computer readable storage medium as defined in claim 15, wherein the characteristic includes at least one of a last time that the virtual machine was powered on, a last time that the virtual machine was remotely accessed, or an amount of the computing resources consumed by the virtual machine.
