Cloud computing is considered as the beginning of another internet revolution In recent years. Many governments of countries are developing the cloud computing industry. To deal with of hundreds or thousands of hosts behind cloud computing services, If there were no a rapid and scalable deployment method, it would make get half the result with twice the effort. This paper proposes an approach, which can rapid deploy virtualization environment and totally used computing and storage resources. In our experiment , We found that it save around the 70% of deployment time, and prove the rate of saving time proportional to the number of deploying hosts.
