Benefits for user

To leverage cloud computing from a user perspective, there should be three basic questions to address :

1. How far am i willing to share a component of my Enterprise Architecture (EA) ?
2. Does the targeted Cloud Computing service fit into my Information System architecture ?
3. What roles in my IS organisation do i expect the Cloud Computing supplier to fulfill ? 

From a methodological stance, a Cloud Computing journey can be planned in a three dimension space : strategic, technical and relational.
