"Cloud" fog in the most popular words to let you understand cloud computing

The sky edge out of Chi Yun, Europe and China and new push 4g cloud navigation, more and more "cloud" appears in our vision, ask what is "cloud", may get such answer: cloud computing. Oh, cloud computing, I've heard of it. Then ask, what is cloud computing? A professional answer to this question must be a long speech, perhaps not finished it has been "foggy." Is there a popular explanation? Why use cloud computing? Small part of this has a little understanding, as far as possible with the popular words written out, the right to be a trigger.

What is cloud computing

In terms of academic definition, cloud computing (cloudcomputing, Taiwan Translation Cloud computing) is a dynamic and scalable resource computing method that typically provides virtualization via the Internet, with no need for users to understand the details inside the cloud, or to have expertise within the cloud, or to control the infrastructure directly. Narrow cloud computing refers to the delivery and usage patterns of IT infrastructure, which means acquiring the required resources (hardware, platform, software) on an as-needed and extensible basis over the network. A network that provides resources is called a "cloud." The resources in the cloud can be extended indefinitely by the user, and can be obtained at any time, on demand, at any time, and paid for by use.

If you think the above definition is too obscure, one of the predecessors of the statement is very straightforward: cloud computing is the Internet as a large resource pool, our local apart from the basic terminal equipment (not limited to the type, may be the PC, mobile phone, television, even refrigerator washing machines, etc.) and these terminals have only basic functions (visual, can be input, audible, power, other than the ability to directly from the Internet to get, remember! We get just the part we need, and we only pay for that part (luck may be free).

This is the easiest to understand, the most popular commentary. To put it simply, cloud computing is a way to get resources on demand.

The advantages of cloud computing

If you can't imagine the advantages of cloud computing from the commentary, I'll simply say it. The first is flexibility, and it's important to take as much as you need. For example, buy an apple, I want to eat and eat only one and a half, but the boss certainly can't sell a half to me, I either buy a will, or buy two waste half. But in the "cloud computing" way, I can buy only one and a half apples.

The second is unlimited, or not reduced, this can imagine the online video, you see this video even downloaded, as long as the video has not been deleted, it is still there and will always be there, it has not diminished. The same is true of the resources in the cloud, not because you have acquired a part of it. But unlike the video site, the cloud is a broader and even limitless space where you can place everything without worrying about the lack of space.

One big advantage of cloud computing is the low demand for local devices. That means your device can have no player, no Office software, no image processing tools, all of which are available on the Internet via cloud computing.

The current situation of cloud computing

Look at these, do you still feel a little foggy? That's normal. Because it is not easy to fall into the cloud, more is still at the conceptual level. Cloud computing's power is destined to require a lot of equipment and unlimited storage space, but also requires strong computing power, and now can fully meet these requirements of enterprises and even groups are not many. In addition, to achieve cloud computing also requires high-speed broadband access, although now many coastal cities to reach the 10M or even 20M broadband but I think this speed is far from enough.

Like real-time traffic on the Internet, we all know that it's important and good, but it's not something that all businesses can do, and even the companies that claim to land are far from meeting expectations.

One of the pitfalls of cloud computing is security. Some people regard security as an advantage of cloud computing, but it is clear that cloud computing still relies on the internet, even though the firewall is still hard to prevent hackers, and this is the use of cloud computing users have to face the problem.

Small Editor's message: Cloud computing is a more advanced way of resource acquisition, to fully realize cloud computing is not so easy, to really completely understand cloud computing is not a small series of these words can be done, small series of knowledge is limited, only the most basic things present to everyone, a good idea.
