Cloud computing is a new computing model. One of its notable advantages is that cloud computing users can use services from the Internet anytime, anywhere, and pay by usage. When you need to increase (or reduce) computing power, you can get (or release) resources immediately, whereas in traditional data centers (not private cloud environments) users need to purchase hardware, install configuration operating systems and middleware software, and deploy applications. The difference between the two approaches in operation and maintenance is clear, which is one of the main reasons why cloud computing can be hot-won and chased by the industry.
