Who needs cloud computing companies to really enjoy SaaS without pain?

The rationale for cloud computing is to distribute computing across a large number of distributed computers, rather than on local computers or remote servers, where enterprise data centers run more like the Internet. This allows the enterprise to switch resources to the required applications and to access the computer and storage systems as needed.

At the moment, PCs are still the core tool in our day-to-day life-we use PCs to process documents, store data, and share information with others via email or u disk. If the PC hard drive is broken, we will be stranded because of data loss. In the "Cloud computing" era, the cloud will do the work of storing and computing for us. "Cloud" is the computer group, each group includes hundreds of thousands of units, and even millions of computers.

The benefit of the cloud is that the computer can be updated at any time to ensure that the cloud is immortal. Google has several such "clouds", and other IT giants, such as Microsoft, Yahoo and Amazon, have or are building such "clouds". At that time, we only need a computer to be able to access the Internet, do not need to care about the storage or calculation of which "cloud", but once necessary, we can use any equipment, such as computers, mobile phones, to quickly calculate and find this information. We don't have to worry about losing data any more.
