Overview
More and more enterprise are thinking about how to leverage the usage of private cloud and public cloud. Public cloud have very good scalability and have cost advantage in many cases, while Private cloud have more security assurance and have more feasibility for IT administrator. It is a hard decision to choose just one of them. A traditional Cloud Broker can provider a basic multi-cloud management function, but it is not a good experience for the administrator, since they still feels like they are using multiple separated clouds with a unified UI style. What's worse is that they need to learn one more type of operational mode and API besides the existing clouds APIs.
A hybrid cloud solution is required, which will provide smooth inter-cloud management which makes you feels just like managing one cloud, and it should provide the existing standard API and operational mode which makes you shorten learning curve and easy to integrate with industry existing services.

Use Case
Cross Cloud Deployment
A typical web application is composed with 3 different tiers, the load balancer tier, the web front tier, and the app backend tier. Users have a private cloud based on OpenStack or VMware and so on, which just has less resources but more secure than public clouds. So they can use the standard OpenStack API to launch the web service's backend virtual machines in private cloud, launch the load balancer and web front virtual machines in the public clouds.
Cloud Burst
In some cases, user would not like to put anything in public cloud if not necessary. User would like to put all parts of the application in private cloud usually, and they would like to scale the web front end in case of there is a 'Cloud Burst' comes. For example, I have a online shopping mall in my private cloud, the system resource and internet bandwidth is enough in normal case. But there will have a bottleneck in big festival period, so I would like to scale out my application to public cloud in that period, and I would like to scale in my application back to private cloud after the big festival.
