Abstract

A method is provided herein for managing a plurality of computing entities. The method includes sending a dynamic attribute dependency to one or more of the computing entities. The dynamic attribute dependency specifies a constraint for performing the management operation based on a dynamic attribute of each of the one or more computing entities. Additionally, the method includes scheduling, based on the plan, an atomic task configured to perform the management operation on each of the one or more a computing entities based on whether the constraint is resolved. The method further includes performing the atomic task if the constraint is resolved.

Claims

1. A method for managing a plurality of computing entities, comprising:

sending a dynamic attribute dependency to one or more of the computing entities, wherein the dynamic attribute dependency specifies a constraint for performing a management operation on the one or more computing entities;

scheduling, according to a plan, an atomic task to perform the management operation on each of the one or more computing entities; and

performing the atomic task if the constraint is resolved.

2. The method recited in claim 1, comprising determining that the constraint is resolved synchronously.

3. The method recited in claim 2, comprising querying the corresponding computing entity to determine whether the constraint is resolved.

4. The method recited in claim 1, comprising determining that the constraint is resolved asynchronously.

5. The method recited in claim 4, comprising receiving an event from one of the computing entities, wherein the event indicates the constraint is resolved.

6. The method recited in claim 5, comprising

generating a buffer for each of the atomic tasks, wherein the buffer is configured to receive the event;

and

sending a reference identifying the buffer to the corresponding computing entity.

7. The method recited in claim 1, wherein the constraint specifies a condition for the dynamic attribute, and wherein the constraint is resolved if the condition is met.

8. The method recited in claim 1, wherein the constraint is resolved during a specified time range.

9. The method recited in claim 1, wherein the atomic task is performed within a specified time period after the constraint is resolved.

10. A system for managing a plurality of computing entities, comprising:

a processing unit; and

a system memory, wherein the system memory comprises code configured to direct the processing unit to;

send a dynamic attribute dependency to one or more of the computing entities, wherein the dynamic attribute dependency specifies a constraint for performing the management operation, wherein the constraint specifies a condition for a dynamic attribute of each of the computing entities, and wherein the constraint is resolved if the condition is met during a specified time range;

schedule, based on a plan, an atomic task to perform the management operation on each of the one or more computing entities; and

perform the atomic task if the constraint is resolved.

11. The system recited in claim 10, wherein the system memory comprises code configured to direct the processing unit to determine that the constraint is resolved synchronously.

12. The system recited in claim 11, wherein the system memory comprises code configured to direct the processing unit to query the corresponding computing entity to determine whether the constraint is resolved.

13. The system recited in claim 10, wherein the system memory comprises code configured to direct the processing unit to determine that the constraint is resolved asynchronously.

14. The system recited in claim 13, wherein the system memory comprises code configured to direct the processing unit to receive an event from one of the computing entities, wherein the event indicates the constraint is resolved.

15. The system recited in claim 14, wherein the system memory comprises code configured to direct the processing unit to:

generate a buffer for each of the atomic tasks, wherein the buffer is configured to receive the event; and

send a reference identifying the buffer to the corresponding computing entity.

16. One or more computer-readable storage media, comprising code configured to direct a processing unit to:

send a dynamic attribute dependency to the one or more computing entities, wherein the dynamic attribute dependency specifies a constraint for performing the management operation;

schedule, based on a plan, an atomic task corresponding to perform the management operation on each of the one or more computing entities based on whether the constraint is resolved;

determine that the constraint is resolved asynchronously; and

perform the atomic task if the constraint is resolved.

17. The one or more computer-readable storage media recited in claim 16, comprising code configured to direct the processing unit to receive an event from one of the computing entities, wherein the event indicates the constraint is resolved.

18. The one or more computer-readable storage media recited in claim 17, comprising code configured to direct the processing unit to

generate a buffer for each of the atomic tasks, wherein the buffer is configured to receive the event;

and

send a reference identifying the buffer to the corresponding computing entity.

19. The one or more computer-readable storage media recited in claim 16, wherein the constraint specifies a condition for a dynamic attribute of each of the computing entities.

20. The one or more computer-readable storage media recited in claim 16, wherein the constraint is resolved if the condition is met during a specified time range.
