The use of formal methods is an effective means to improve complex systems reliability and quality. In this context, we adopt one of these methods to formalize cloud computing concepts. We focus on modeling interactions between cloud services and customers. Based on Bigraphical Reactive Systems, the formalization process is realized via the definition of a Cloud General Bigraph (CGB) obtained by associating; primarily, a CCB (Cloud Customers Bigraph) to cloud customers. Then, a Cloud Services Bigraph (CSB) is proposed to formally specify cloud services structure. Finally, juxtaposing these two bigraphs (CSB and CCB) gives rise to the suited CGB. In addition, a natural specification of cloud deployment models is specified. This paper also addresses cloud service dynamics by defining a set of reaction rules on bigraphs in a way that is amenable to reconfigure the designed cloud system.
