Cloud computing is superior to terminal computing and centralized computing

In today's working life, we face three computing models, personal computing, centralized computing, and cloud computing. If you are running software on your own laptop or workstation, it is personal terminal computing; centralized computing is provided by your business's data center or computer room to provide computing resources; now everyone is talking about cloud computing, which is entirely provided by third parties to compute resources. Three computing modes for network connectivity requirements are also very different, in comparison, cloud computing network connectivity requirements of the highest performance, centralized computing second, personal terminal computing again. These three models also have advantages and disadvantages, the key to see who.

Personal Terminal Computing is the use of your own resources to run applications, network connection to the local hardware, the advantage of this calculation is that the resources are your own, as long as you pay a certain fee, you can run for a long time, and because everything is running locally, so the requirements of the network link is not high. The inconvenient part is that you have to use it in front of your computer, which is a huge limitation for people with a strong mobility.

Centralized computing is where your IT department runs your application with resources such as computing and disk, and is connected to the company's data center via a LAN, such as a Microsoft Exchange Server in a corporate data center. This way, the application is run by the IT department, and you don't have to know much about it, but at the same time you're missing more choices, and it's just what you're applying to the IT department.

The industry is now widely concerned about cloud computing and personal terminal computing and centralized computing is a big difference, it is completely unrelated to the third party with the use of shared resources for you to run the application, through the Internet to link to a place, you do not have to care about where this place. For example, if you use Gmail via the Internet, your message is placed in a Google data center that you don't know anything about. The advantage of cloud computing is that you just need to know how to use the application, without having to know everything about it and not being bound by the computer, whether you're using a laptop, a cell phone, or any other Internet-connected device, you can always use the application you want. However, these data storage, computing, connectivity, disaster preparedness, etc., are outsourced to a third party, so strong network connectivity is extremely important.

Thus, through the comparison of three kinds of computing models, cloud computing is really good, is indeed a problem of the beholder. Whether you want to use cloud computing, the key to see if it can really improve your productivity. For example, for a large company with its own complete and efficient data center, the use of outsourced cloud services may not only improve efficiency, but will reduce your productivity, but for many small and medium-sized enterprises, the sharing of cloud computing resources with other companies brings high efficiency. In addition, cloud computing providers offer different services and measure different metrics. If a cloud service provider simply provides simple networked storage, it is simpler, and if it is a product for enterprise applications, the data center requirements for delivering cloud computing are high, with high reliability, fault tolerance, and availability.
