How cloud computing called?
According to IBM, the cloud or cloud for short, is the delivery of computing resources to users depending on the purpose of use via an Internet connection. Resources that can be anything related to computing and computer, such as software, hardware, network infrastructure to servers and large server networks.
Before the cloud cloud, you want to do something, and to do your own, invest own money almost from start to finish. In the role of individual users, if you want to save the data, you have to spend money to buy a hard drive. You want to back up data regularly and immediately? In addition to hard drives also have to go for the software, connect it to the network itself if desired. If you want to make a website, you have to buy the server itself on assembling and configuring everything. You want to manage the sales of home stores, you have to go buy accounting software or software sales and then install it on the computer at home.
And all these things do not just stop at the time of purchase. The money you spend goes with you then, tentatively called the money "maintenance" and "maintenance". You buy the hard drive, then missed it damaged self you must take away the warranty. Bad luck all the warranty period, the data loss has cost just more money to buy another drive. You install the server, then you have to maintain it, take care of the cooling system, take care of backups (or if you hire someone else to do the machine is no different, only that you spend money because they do help blow). Accounting software you installed, and then each time it updates, you must go to reinstall on your computer, if there is an error, you must manually edit (or call the company to ask how to fix).

that this problem first glance it may seem simple but it actually cost you a lot of effort and money, not to mention that it also makes it easy to lose important data (like in the example above the hard drive). For businesses, the cost of "maintenance" is also great because they not only spend small software like Word format, Excel, PowerPoint which is the management system and the massive complex, with data on the continuous so only a small failures can also cause loss of revenue or even millions of dollars as the production stalled. They have to feed a staff to install, configure, test, run, secure and update your system. If you bring that amount multiplied by the number of business app that hundreds of users, it is clear that cost is not the slightest little.
Then the advent of cloud computing, it helps resolve part you have to manage the their hardware and software. You need to save the data? There OneDrive with Dropbox, Google Drive can help you. Obviously you do not need to care about your files are stored on the HDD yet, it has broken or not, no need to backup the secondary HDD or not, it is located in any place. You also do not need interest in connection with other machines this machine to receive files in two places. Everything was "take care of" by the cloud service provider and so, in this case it is Dropbox, Google or Microsoft. If the HDD fails, they will replace themselves, they would do themselves periodically backup operation, you do not have to bother.
Another example: the phone book. Previously, you had to backup their contacts to computer periodically, to keep the file directory, and then if you change your phone contacts, they must reinstall very laborious. Now it has Google, Apple, Microsoft and BlackBerry worry about your contacts. Each time you add a new number, contacts will be synchronized to the "cloud" and contains. In case you switch to a different phone, contacts can be downloaded quickly. No more frequent backups, no need to copy files manually.
For now, they began to move the application or your software to the cloud. Need accounting software? Just go to your browser, click a few click, done. You do not need to care about the software that is installed was, installed on a server with an IP address is how much, when it also automatically update as always. Just open it up and use it. Want to expand? Ease ẹc, pay extra to have more users. Want to run 24/7 without having to think of electricity for air conditioning to cool? Also always.
