Cloud service cost-optimal data center assignment

1. A non-transitory computer readable medium embodying instructions executed by a processor to perform a method for service creation and mapping between at least two support systems, the method steps comprising:

provisioning a service based on a service requirement and a plurality of available data centers;

collecting a value of the service requirement and a cost associated with the service;

comparing the service requirement to resource types of a plurality of data centers and resource availability of the plurality of data centers to determine a plurality of valid data centers among the plurality of data centers, the plurality of valid data centers having respective resource type and a respective resource availability matching all the service requirements; and

selecting a valid data center from among the plurality of valid data centers with a minimum cost for service placement and provisioning.

2. The computer readable medium of claim 1 , wherein the at least two support systems include a business support system and an operations support system.

3. The computer readable medium of claim 1 , wherein the provisioning is performed at service delivery time.

4. The computer readable medium of claim 1 , further comprising maintaining a plurality of resource constraint models for each of the plurality of data center.

5. The computer readable medium of claim 4 , wherein the plurality of resource constraint models include a resource type based model corresponding to the catalog and an availability based model corresponding to the capacity.

6. The computer readable medium of claim 1 , further comprising maintaining a cost model for each of the plurality of data centers that associates a cost to a respective resource type.

7. A non-transitory computer readable medium embodying instructions executed by a processor to perform a method for service creation and mapping between at least two support systems, the method steps comprising:

modeling requirements of a plurality of existing services;

modeling an environment comprising the plurality of existing services;

receiving a subscription request to a new service with parameters;

creating a service model of the environment including the new service based on the parameters;

accumulating data center level requirements from the service model;

comparing the data center level requirements against each a catalog and capacity of a plurality of data centers to determine a plurality of valid data centers among the plurality of data centers, the plurality of valid data centers having a respective catalog and a respective capacity matching all the data center level requirements;

discarding at least one data center of the plurality of data centers that does not fulfill the data center level requirements;

accumulating a measure of cost for deploying the new service in each of the plurality of valid data centers; and

deploying the new service in at least one of the plurality of valid data centers based on the measure of cost.

8. The computer readable medium of claim 7 , further comprising maintaining a plurality of resource constraint models for each data center.

9. The computer readable medium of claim 8 , wherein the plurality of resource constraint models include a resource type based model corresponding to the catalog and an availability based model corresponding to the capacity.

10. The computer readable medium of claim 7 , further comprising maintaining a cost model for each data center that associates a cost to a respective resource type.
