The branch of cloud computing closest to the crowd - personal cloud storage

Cloud computing is one of the hottest concepts in recent years, and one of the most popular branches of the concept by far is the personal cloud storage. From the world-famous dropbox to the innumerable "network disk" products in China, more and more Internet users have begun to move their data from the computer hard disk to the cloud.

When we look back at history, we can understand that in fact, "the need to keep documents anywhere (such as online) and then access them anywhere" has always existed.

Many years ago, when we were still using the DOS6.22 era, then the popular way is to use a floppy disk. Just copy the files you want to use to a floppy disk, and you can bring the floppy disk to you. Anytime, anywhere, as long as there is a floppy drive installed on the computer, you can use the floppy disk files.

Later, a floppy disk 1.44MB capacity began to be unable to meet the needs of more and more people, and due to technical constraints, the floppy drive read speed is too slow, coupled with the emergence of USB, U disk came into being. This mobile storage device not only smaller than the floppy disk, faster than the floppy disk, not easy to damage, it is important that its capacity can be much larger than a floppy disk.

Later, the Internet started to popularize, but at that time, there was not a very convenient file storage service for ordinary Internet users on the Internet at that time. So everyone "development" out of a unique way: many friends log in their own mailbox, and then send myself an e-mail, with attachments. In this way, the files in the attachment can be permanently stored in the mailbox, which can be used on any computer with Internet access. Operating the browser is much easier than plugging and unplugging U disk (especially, there are some assembled chassis, the front USB interface is not enough power supply. We often need to climb to the back of the chassis ...), more importantly, many mailboxes can Free application, even the money to buy storage devices are saved.

In recent years, we have found a problem, that is, the general upper limit of about 20MB attachment mailbox started not enough. Because everyone starts to store more and larger files. There are some mailbox services continue to upgrade the mailbox capacity, but the attachment capacity has not changed, did not solve this part of the user's needs. QQ mailbox was found this pain point, introduced a "large attachment" function, successfully alleviated this part of the demand. However, perhaps due to cost constraints, "oversized attachments" are generally deadline-for example, only seven days. Although every seven days you can go manually click on the "renewal." But when once forgotten, it tragedy.

On the other hand, many people start to have more than two computers, and are using smartphones, iPads and other devices at the same time. In this environment, it is natural that there is a need to "share (synchronize) information on all devices." Dropbox found this requirement, but the team at the time was not yet sure how big the demand was. So the smart dropbox team created a video called "What is Dropbox," telling users a tool called "dropbox" that not only saves your files, but also automatically syncs them to all your devices. This video got a very high clickthrough rate on YouTube. So they expanded the team, started really developing this product, and succeeded.
