Regardless of the model, cloud frameworks should all provide the ability to dynamically scale, develop, and deploy rapidly, and have the appearance of locality regardless of proximity:

Private clouds also imply on-premise managed components. Modern enterprise systems tend to use a hybrid architecture to ensure the safety of mission-critical applications and data on-premise, and use the public cloud for connectivity, deployment ease, and rapid development.
