3. The computer-implemented method of claim 1, wherein:

the data or functional component modeled by each class is one of a virtual device supporting a cloud-based environment, a service utilized in the cloud-based environment, a software role performed by an installed application in the cloud-based environment, a data package holding data to be used during deployment or operation of the cloud-based environment, or a combination of one or more thereof.

4. The computer-implemented method of claim 1, wherein:

the specification language supports at least one of dependency between class definitions and connectivity between class definitions, and where a definition dependency between a first class and a second class represents a deployment dependency between respective components modeled by the first and the second class, and where a value assignment linking an instance of a second class to a class parameter of a first class represents a connectivity between respective components modeled by the first class and the second class.

31. The computer-implemented method of claim 1, further comprising:

monitoring respective performance of each of the multiple of the plurality of cloud-based deployments;

determining that the trigger event has occurred; and
