Resource Sharing in a pure plug and play model that dramatically simplifies infrastructure planning is the promise of cloud computing. The two key advantages of this model are ease of use and cost effectiveness. Cloud Computing also offers vast amount of resources available for end users. The opportunity to choose between several cloud providers is alluded by complexity o cloud solution heterogeneity. Challenges with cloud deployment and resource provisioning are identified in this paper. To tackle these challenges a model based language named cloud ML is proposed. This language is supported by an engine able to provision nodes in the cloud.
