Abstract: Disclosed is a computer-implemented method, system and computer program(s) for migration of a source machine instance to a target machine instance of least one heterogeneous virtual server device managed within a cloud computing environment. The method includes discovering machine images of a cloud service provider and storing results in a computer-readable catalog containing cloud metadata comprised of machine image identifiers and information discovered about the machine images. The method further includes, in response to a request for migration document in a computer-readable form that comprises a specification of a required migration target machine instance, specifying weight/priority information for components to be included in the target machine instance, where the weight information indicates weights for operations comprising component installation, component removal and component upgrade in the target machine instance.

Abstract: The invention broadly and generally provides a method for calibrating the relationship between management-inherent complexity metrics deriving from the management structure and human perceived complexity of information technology management comprising: (a) obtaining a set of management-inherent complexity metrics; (b) obtaining a set of human-perceived complexity metrics; (c) constructing a control model identifying a set of dominant indicators selected from the aforesaid set of management-inherent complexity metrics; (d) establishing a value model mapping from the aforesaid set of dominant indicators to the aforesaid set of human-perceived complexity metrics.

Abstract: The invention broadly and generally provides a database comprising at least one record, the aforesaid at least one record comprising: (a) solution metadata relating to an information technology solution; and (b) evaluation metadata relating to a complexity evaluation of the aforesaid information technology solution.

Abstract: Techniques for forming a document model for constructing a semantically and syntactically valid document are provided. In one embodiment, a method for forming a document model for constructing a semantically and syntactically valid document includes the steps of: creating a root tag element corresponding to a root of the document to be constructed, the root tag element including information relating to a corresponding tag; associating one or more model elements with the root tag element, each model element representing an alternative to the information relating to the corresponding tag; and for each of the model elements, creating a syntactically and semantically valid sub-tree of elements based at least in part upon a structure of the document to be constructed under one or more predetermined conditions.
