receiving an auditing request for a specific change in a particular service deployed in the datacenter;

responsive to receiving the auditing request, identifying a status of deployment of the particular service from the change management system; and

14. The computer implemented method of claim 1 , wherein the modification of the set of services executing on the datacenter is specified via an artifact version map.

15. The computer implemented method of claim 14 , further comprising:

determining the modification of the set of services executing on the datacenter by comparing the artifact version map with a previously received artifact version map.

16. A non-transitory computer readable storage medium for storing instructions that when executed by a computer processor cause the computer processor to perform steps for configuring datacenters in a cloud platform, the steps comprising:

accessing a datacenter configured on a target cloud platform, the datacenter executing a set of services, the datacenter comprising a hierarchy of datacenter entities, wherein each datacenter entity comprises (1) one or more services or (2) one or more other datacenter entities;

receiving a modification of the set of services executing on the datacenter;

generating a master pipeline for deploying services on a target cloud platform, the master pipeline comprising:

executing each of the set of pipelines, wherein execution of the change management stage of a pipeline provides a status of deployment of one or more services to the change management system.

17. The non-transitory computer readable storage medium of claim 16 , wherein the instructions further cause the computer processor to perform steps comprising:

receiving an auditing request for a specific change in a particular service deployed in the datacenter;

responsive to receiving the auditing request, identifying a status of deployment of the particular service from the change management system; and

providing the identified status of deployment of the particular service in response to the auditing request.
