What is the biggest headache problem you have when you use your PC? The answer is probably "the computer itself." System crashes, data loss, hard drive failures, and so on. Now there is a new trend in the technology industry, which is expected to eliminate many of these thorny issues, that is, "cloud computing."

Many people have heard the hype, but there is still a question: What is cloud computing and what does it mean for our future? This article gives some answers.

Q: What is cloud computing?

A: In fact, cloud computing refers to a pattern: the applications you use and the saved files are stored on a remote server. You can access these applications and files using your own PC over the network (in many cases the Internet). Cloud computing is not really a new concept, and the old concept is once again a concern, thanks to the growing popularity of computer networks, especially the Internet, and the growing availability of "ready to connect" broadband connections.

Q: What are the advantages of cloud computing?

A: A lot of advantages. As a computer user, you will no longer rely on a particular computer to come and ask for data processing. As long as you can connect to your data over the network, whether it's a LAN or the Internet, you can retrieve your own files and continue to work on the last unfinished job. This convenience is becoming increasingly important because people crave greater mobility and often use more than one computer a day.

You don't have to worry about maintaining your own applications or files, or worrying about the health of your local hardware as you used to. In the cloud computing model, the security of your data is not dependent on the health of your computer hardware: For example, if your laptop crashes, it's a big deal to buy a new hard drive instead of worrying about losing a paper that you've been working on for weeks.

If your computer is in a cloud computing environment, the computer itself becomes smaller and lighter. You no longer need to buy a lot of local storage, because many of the heavy work that runs the application will be done over the network; You may not need the fastest processor or large capacity memory. Smaller, lighter computers can also reduce energy consumption. For many companies, energy efficiency alone is expected to achieve significant benefits.

Cloud computing also brings new opportunities for many people to collaborate. Because of file Remote Storage and because of the right software, multiple users can access these files, so you can share your work with multiple authors.

For many companies, cloud computing offers the opportunity to centralize the data that employees create and secure them. The most common computing pattern today is that employees carry data with them on laptops, but laptops are extremely vulnerable to all kinds of dangers and disasters. Cloud computing is expected to change the situation.

Q: What are the drawbacks of cloud computing?

A: If you put your applications and data on a network, but you cannot access and access the network reliably and securely, cloud computing will not interest you. If you think about storing your data far away and your application is not installed on your computer, you lose too much control, and cloud computing may simply not be able to afford your appetite. This pattern undoubtedly requires computer users to change their mind, and it takes a while to get used to it.

But beyond that, there are some big concerns about data security in the area of cloud computing. Large numbers of data are stored in remote, large-scale "data centers", which are tempting targets for hackers and others who think they have the power to hold information. Companies need to be sure that their data is truly secure.

In addition, reliability is still a problem. If the network is paralyzed or if the connection to the network is paralyzed, you will not be able to access your data unless the problem is resolved. In addition, if the data center that stores your applications and data is faulted or closed, you can only blame yourself for being unlucky unless the problem is resolved.

In addition, while cloud computing is theoretically more environmentally friendly from a user's point of view, all of that data and applications must be stored on a machine somewhere, but these machines are running at any time and thus consume considerable energy.

Q: What are some examples of cloud computing applications?

A: Over the years you may have been slowly moving closer to the cloud computing environment, just not realizing it. For example, if you have an Internet email account, you can say that you are adding cloud computing trends. For example, most Yahoo or Gmail users retrieve, read, and write emails via the internet. Without cloud computing, they would not be able to use e-mail applications or access the e-mail itself. Google Docs has a very powerful and free online word processor, spreadsheet program, and documentation demo program, which is an example of how traditional Office applications are used in cloud computing mode. Microsoft has also announced plans to provide an office productivity tool kit on the Web, in a cloud computing environment. From popular financial app makers to game developers, other app makers are doing the same.

Q: Can i buy a cloud computer?

A: Yes. Some laptops today are actually cloud computers. Asus ' Eee PC and Dell's Inspiron Mini are two examples of laptops that were designed primarily to take into account network connectivity. This first generation of "cloud computing" has little local storage capacity, indicating the future direction: the heavy work of data and application storage and management is being handled far and away.
