In real life, we will store most of our savings in banks or entrust financial institutions to manage them. At the same time, there will be a certain amount of money in the wallet, has been a rainy. In fact, this is the cloud storage implementation model. In cloud storage, a common storage center, such as a data storage server on a network, is used to store enterprise data like a bank. At the same time, some of the more commonly used data will be stored locally (this is like the user's wallet) to facilitate the user's use. This is the rationale behind the combination of cloud computing and data storage. The idea is good. But the concrete realization ...
