Cloud computing is becoming day by day wider providing a vibrant technical environment where innovative solutions and services can be created. Cloud promises cheap and flexible services to end-users. However, Cloud business models and technologies introduce critical issues, such as proprietary API, lack of interoperability, unpredictable performance, and unexpected outages.
The abilities to use multiple Clouds and to migrate, at design or at run-time, applications from one Cloud to another could mitigate the risk of Cloud adoption and would allow building high performance and reliable applications.

The goal of this workshop is to bring together researchers and practitioners who investigate concepts, models and tools for running applications on multiple and heterogeneous Cloud systems.
