Cloud Computing platforms offer diverse services and capabilities with own features. Hence, the provider services could be used by end users to compose a heterogeneous context of multiple cloud platforms in order to deploy their cloud applications made up of a set of modules, according to the best capabilities of the cloud providers. However, this is an ideal scenario, since the cloud platforms are being conducted in an isolated way by presenting many interoperability and portability restrictions,
which complicate the integration of diverse provider services to achieve an heterogeneous deployment of multi-cloud applications. In this ongoing work, we present an approach based on model transformation to deploy multi-cloud applications by reusing standardization e orts related to the management and deployment of cloud applications. Specifically, using mechanisms speci ed by both standards, TOSCA and CAMP, we propose
a methodology to describe the topology and distribution of modules of a cloud application and to deploy the interconnected modules over
heterogeneous clouds. We illustrate our idea using a running example.
