This dissertation thesis deals with Cloud Computing (CC) in terms of IaaS (Infrastructure as a Service) portability. It analyses current status in CC, mainly in standardization of interoperability and portability of CC solutions. Based on current status research, the thesis suggests to use MDA (Model Driven Architecture) as reference architecture, which is used for proposal of transformation rules for IaaS environment description and therefore uses them as answer for IaaS portability problem. The thesis elaborates generic MDA model dealing with IaaS environment description and then suggests transformation rules for transcription of implementationally dependent IaaS services description on specific implementations (OpenStack vs. Amazon Web Services vs. Microsoft Azure) to generic description. Suggestion and usage of generic model and also transformation process as answer to portability of IaaS service is practically verified on real implementations of three largest IaaS providers – Amazon AWS, Microsoft Azure and OpenStack.
