Before we talk about the cloud computing data Center, we need to understand what is cloud computing? Cloud computing refers to the delivery and usage patterns of IT infrastructure, which means acquiring the required resources over the network in an on-demand, extensible manner. A network that provides resources is call
Lead: The Wall Street Journal commented today that when more and more objects become "intelligent", they can feel the surrounding environment or be connected to the Internet and receive remote commands, the insufficient network speed makes cloud computing unable to meet the massive data storage, transmission and processing needs. At this time, some technology companies have put forward a new concept of "fog

Because fast with the Apple Helper support IOS 7 do not jailbreak free installation of genuine game software, so use the fast Apple Assistant to the mobile phone game software back up, successfully upgraded to the 7 official version of iOS after the installation to the device.

Cloud security is not a short-term issue. If cloud computing wants to continue and develop for a long time, the data security issue cannot be underestimated. In this article, the security protection of data source is the most important. Therefore, when using cloud technology
In order to ensure data security, the data needs to be backed up regularly. There are a number of ways to backup, and the effect is different. Once there is an error in the data in the database, you need to use the backed-up data for restore recovery. Thus minimizing the los
