instantiate the cloud service based on the updated topology.

14. The system of claim 13 , wherein adding the information of the first policy to the first node comprises adding location information of the first policy to the first node.

15. The system of claim 14 , wherein the number of policies comprise a policy selected from among:

a provisioning policy that guides an optimization and an instantiation of a number of computing devices within the cloud service, or provides a workload management at provisioning of the cloud service, or guides monitoring polices for provisioning of the cloud service, or guides event handling for provisioning of the cloud service, or guides remediation for provisioning of the cloud service, or a combination thereof;

a resource provider policy that guides a selection of a number of resources associated with a number of resource providers' offerings;

a management policy that guides management functions performed on the number of nodes and relationships of the topology;

the monitoring policy that determines how the number of nodes are to be monitored, or determine how to setup a monitoring system to monitor the number of nodes, or determines how to process events, or determines how to process incidents, or a combination thereof; and

a security policy that determines how to setup an existing monitoring system to protect the number of nodes, or determines how to setup a new monitoring system to protect the number of nodes, or determines how to process events, or determines how to process incidents, or a combination thereof.

16. The system of claim 13 , wherein the associating of the number of LCMAs with the number of nodes comprises associating a first LCMA of the number of LCMAs individually with a node of the number of nodes.
