Nowadays cloud computing is supposed to be the new paradigm in computer sciences. Being new compass it is believed to reshape the company-IT infrastructure relation, as organizations realized that more outsourcing allows more focus on core competencies and generating profit. That’s why the role of the IT department within the organizations is expected to stand in front of an elemental metamorphosis. Cloud computing needs new methods not exclusively in the field of business analysis but also in the management of IT planning, road mapping and operation.

The turnout of the current paradigm isn’t only in the heads: architectural planning needs new technology know-how. Assuming that the analogy is right, the actually situation of the IT industry can be compared to the energetic industry at the beginning of the XX century: normalization of new standard establishment is unavoidable. Being on this track companies need to step further into the cloud without loosing the competitive edge. In lack of standards, planning and executing the adaptation of the cloud based systems is a huge challenge.

In my thesis I’m intended to establish a methodology, which is able to analyze the complex infrastructure of an organization to be able to support the planning of the architecture and the migration execution when changing between services.

In the first chapters I analyze the causes of the cloud computing. Besides I created my own definition for that concept, as actually it is not an implicit category in the industry. I deploy a new structure along the analysis of a few existing infrastructure concepts based on the ITIL-ITSM model and taking into consideration the expectation of the new way of thinking. Along this structure I feature the actual technologies and services. Despite of the fact that the cloud is not a brand new idea, it’s hard to find a comprehensive methodology for moving the infrastructure to the cloud. After the analysis of this subject, I deployed the Service-orientated Migration Methodology, along a precise specification, which covers the deficiencies. In the last chapter I test the process and proof the concept by planning the partial migration of a concrete enterprise.
