Abstract

In a method of instantiating an information technology (IT) service in light of maintenance requirements, maintenance window instances are determined. The maintenance instance windows are associated with reusable service instances available in a datacenter. The maintenance window instances are analyzed in conjunction with a service model of said IT service to determine a maintenance efficient binding of a selection of said reusable service instances with which to provide an instance of said IT service.

Claims

1. A computer-readable storage medium having instructions stored thereon which, when executed, cause a computer processor to perform a method of instantiating an information technology (IT) service in light of maintenance requirements, said method comprising instructions for:

determining maintenance window instances associated with reusable service instances available in a datacenter; and

analyzing said maintenance window instances in conjunction with a service model of said IT service to determine a maintenance efficient binding of a selection of said reusable service instances with which to provide an instance of said IT service.

2. The computer-readable storage medium of claim 1, further comprising instructions for:

grounding said maintenance efficient binding in said datacenter.

3. The computer-readable storage medium of claim 1, wherein said determining maintenance window instances associated with reusable service instances available in a datacenter comprises:

determining said maintenance window instances based upon a maintenance window model in analyzed in conjunction with scheduled maintenance windows of said reusable service instances.

4. The computer-readable storage medium of claim 1, wherein said analyzing said maintenance window instances in conjunction with a service model of said IT service to determine a maintenance efficient binding of a selection of said reusable service instances with which to provide an instance of said IT service comprises:

performing said analyzing to determine said selection of said reusable service instances which satisfies criteria of said service model and provides a smallest possible maintenance window.

5. A computer-implemented method of instantiating an information technology (IT) service in light of maintenance requirements, said method comprising:

accessing a service model associated with an IT service, said service model comprising a description of a plurality of service instances which cumulatively represent a model of said IT service;

accessing a maintenance window model associated with said service model, said maintenance window model descriptive of maintenance requirements associated with said service instances;

determining maintenance window instances associated with reusable service instances available in a datacenter; and

analyzing said maintenance window instances in conjunction with said service model to determine a maintenance efficient binding of a selection of said reusable service instances with which to provide an instance of said IT service.

6. The computer-implemented method as recited in claim 5, further comprising:

grounding said maintenance efficient binding in said datacenter.

7. The computer-implemented method as recited in claim 5, wherein said determining maintenance window instances associated with reusable service instances available in a datacenter comprises:

determining said maintenance window instances based upon said maintenance window model in conjunction with scheduled maintenance windows of said reusable service instances.

8. The computer-implemented method as recited in claim 5, wherein said analyzing said maintenance window instances in conjunction with said service model to determine a maintenance efficient binding of a selection of said reusable service instances with which to provide an instance of said IT service further comprises:

in an event that a reusable service instance of compatible type and variation is not available for reuse in said datacenter, determining that a new service instance should be created in said datacenter and included in said maintenance efficient binding.

9. The computer-implemented method as recited in claim 5, wherein said analyzing said maintenance window instances in conjunction with said service model to determine a maintenance efficient binding of a selection of said reusable service instances with which to provide an instance of said IT service further comprises:

in an event that a reusable service instance with a compatible maintenance window to said IT service is not available for reuse in said datacenter, determining that a new service instance should be created in said datacenter and included in said maintenance efficient binding.

10. The computer-implemented method as recited in claim 5, wherein said analyzing said maintenance window instances in conjunction with said service model to determine a maintenance efficient binding of a selection of said reusable service instances with which to provide an instance of said IT service comprises:

analyzing a maintenance window associated with a reusable service instance of said reusable service instances to determine if said maintenance window fits within a maintenance window defined in conjunction with said IT service.

11. The computer-implemented method as recited in claim 5, wherein said analyzing said maintenance window instances in conjunction with said service model to determine a maintenance efficient binding of a selection of said reusable service instances with which to provide an instance of said IT service comprises:

performing said analyzing to determine said selection of said reusable services which satisfies criteria of said service model and provides a smallest possible maintenance window.

12. A datacenter management system, said system comprising:

a service instance binder configured to determine a maintenance efficient binding of a selection of reusable service instances with which to provide an instance of an IT service, said reusable service instances available in a datacenter;

a service model communicatively coupled with said service instance binder, said service model comprising a description of a plurality of service instances which cumulatively represent a model of said IT service;

a maintenance window model associated with said service model and communicatively coupled with said service instance binder, said maintenance window model descriptive of maintenance requirements associated with said service instances; and

a plurality of maintenance window instances communicatively coupled with said service instance binder and associated said with said reusable service instances.

13. The system of claim 12, further comprising:

an IT service grounder configured for grounding said maintenance efficient binding in said datacenter.

14. The system of claim 12, wherein said service instance binder comprises:

a binding determiner configured with logic for analyzing said maintenance window instances in conjunction with said service model to determine said maintenance efficient binding.

15. The system of claim 12, wherein said service instance binder comprises:

a maintenance instance determiner configured with logic for determining maintenance window instances associated with reusable service instance available in said datacenter.
