Abstract

Methods and apparatus involve continuous management of workloads, including regular monitoring, profiling, tuning and fault analysis by way of instrumentation in the workloads themselves. Broadly, features contemplate collecting current state information from remote or local workloads and correlating it to predefined operational characteristics to see if such defines an acceptable operating state. If so, operation continues. If not, remediation action occurs. In a virtual environment with workloads performing under the scheduling control of a hypervisor, state information may also come from a hypervisor as well as any guest user and kernel spaces of an attendant operating system. Executable instructions in the form of probes gather this information from items of the stack available for control and deliver it to the management system. Other features contemplate supporting/auditing third party cloud computing services, validating service level agreements, and consulting independent software vendors. Security, computing systems and computer program products are other embodiments.

Claims

1. In a computing system environment, a method of managing workloads deployed as virtual machines under the scheduling control of hypervisors on computing devices having hardware platforms with at least one operating system with guest user and kernel spaces, comprising:

collecting current state information from each of the workloads, hypervisors and guest user and kernel spaces; and

correlating the current state information to predefined operational characteristics for the workloads, hypervisors and guest user and kernel spaces.

2. The method of claim 1, further including determining if any remediation action is required for any of the workloads, hypervisors and guest user and kernel spaces based on the correlating.

3. The method of claim 2, if the remediation action is said required, further including restoring one of the workloads, hypervisors and guest user and kernel spaces to an acceptable operational state.

4. The method of claim 1, further including fulfilling an audit request of a computing cloud in which the workloads are deployed.

5. The method of claim 4, further including comparing usage of the hardware or software platforms to a financial bill from the computing cloud for any discrepancies.

6. The method of claim 1, further including validating contract terms of a service level agreement.

7. The method of claim 1, further including inserting probes of executable instructions onto the hardware platforms to said collect current state information from said each of the workloads, hypervisors and guest user and kernel spaces.

8. The method of claim 1, further including prioritizing the collected current state information.

9. The method of claim 1, further including storing the collected current state information for later use as earlier collected state information during the correlating to the predefined operational characteristics.

10. In a computing system environment, a method of managing workloads deployed as virtual machines under the scheduling control of hypervisors on computing devices having hardware platforms with at least one operating system with guest user and kernel spaces, comprising:

deploying the workloads for use on the hardware platforms at a location remote or local to an enterprise;

collecting current state information from each of the workloads, hypervisors and guest user and kernel spaces;

providing the collected current state information to a computing device located at the enterprise; and

at the computing device at the enterprise, correlating the current state information to predefined operational characteristics for the workloads, hypervisors and guest user and kernel spaces.

11. The method of claim 10, further including determining if any remediation action is required for any of the workloads, hypervisors and guest user and kernel spaces based on the correlating and if the remediation action is said required, further including restoring one of the workloads, hypervisors and guest user and kernel spaces to an acceptable operational state.

12. The method of claim 11, wherein the determining if any remediation action is required further includes conducting fault analysis of the workloads, hypervisors and guest user and kernel spaces by comparing to stored fault signatures.

13. The method of claim 11, wherein the determining if any remediation action is required further includes consulting stored policy statements established by the enterprise.

14. The method of claim 11, wherein the determining if any remediation action is required further includes consulting an independent software vendor at still another location remote from the enterprise in order to establish the acceptable operational state of the workloads, hypervisors and guest user and kernel spaces.

15. The method of claim 10, further including fulfilling an audit request of a computing cloud in which the workloads are deployed at the location remote from the enterprise.

16. The method of claim 15, further including identifying usage of the hardware or software platforms to generate a financial bill from the computing cloud or to identify any discrepancies.

17. The method of claim 10, further including inserting probes of executable instructions into the hardware platforms to said collect current state information from said each of the workloads, hypervisors and guest user and kernel spaces.

18. A computing system to manage workloads deployed as victual machines under the scheduling control of hypervisors on computing devices having hardware platforms with at least one operating system with guest user and kernel spaces, comprising:

at least first and second computing devices having a hardware platform with a processor, memory and available storage upon which a plurality of workloads can be configured under the scheduling control of a hypervisor including at least one operating system with guest user and kernel spaces;

probes of executable instructions configured on one of the hardware platforms to said collect current state information from a respective said workload, hypervisor and guest user and kernel spaces and to return the collected current state information to another of the hardware platforms; and

correlating executable instructions configured on the another of the hardware platforms to correlate the current state information to predefined operational characteristics for the workloads, hypervisors and guest user and kernel spaces, the predefined operation characteristics residing on the available storage for the another of the hardware platforms.

19. The computing system of claim 18, further including executable instructions configured on the another hardware platform that can be delivered to the one of the hardware platforms to restore one of the workload, hypervisor and guest user and kernel spaces to an acceptable operational state in situations requiring remediation therefor.

20. The computing system of claim 18, further including executable instructions configured on the another hardware platform that can generate or audit for discrepancies in a financial bill of a computing cloud in which the one of the hardware platforms is deployed.
