Google Calendar can remind us through a variety of devices that can be , text messages can also be, or even a telephone. 5. Email For a variety of reasons, we will have several different mailboxes. And often view these mailboxes, it bees a very plicated matter, we need to open a different site, enter a different user name and password. Cloud puting service providers a good solution to this problem, through hosting, service providers can be integrated with a number of different messages. For example, Google39。s hard disk. 3. The servers will modify the data back to your puters, puters according to the data, change the display. Among our puter did not participate in the calculation of the main aspects, which have to do is to send data and receive data, that is Cloud Computing. Cloud puting is an Interbased formula, in this way, shared resources and information to ondemand hardware and software available to puters and other equipment. Run like the whole grid. Since cloud puting is an emerging puting technology, it will certainly be a lot of advantages. Cloud puting has four distinct characteristics: 1. First, cloud puting provides the most reliable and secure data storage center, users do not have to worry about data loss, virus attack and other problems All your data is stored in the cloud it? It has been somewhere in the cloud. And desktop puting is different from the desktop environment, hard drive crashes will destroy your all the valuable data. The cloud puter crash will not affect your data storage. Because the cloud data is automatically copied, so there will never be any loss. This also means that even if your PC crashes, all your data is still in cloud, you can still visit. In a few desktop users regularly back up their data world, cloud puting can maintain the security of data. 2. Secondly, the cloud puting on the client devices require a minimum,using is most convenient You do not need highperformance puters to run Webbased cloud application. Because the application in the cloud rather than in their own personal puters run on traditional desktop personal puter software without the required processing power or disk space. Therefore, cloud puting client puter can be cheap, with a smaller hard drive, less memory, more efficient processors. In fact, the client in this case do not even need CD or DVD drive, because the need to l
