Is Cloud computing superior to terminal computing and centralized computing?

In today's work and life, we are faced with three computing modes: Personal terminal computing, centralized computing, and cloud computing. If you run software on your laptop or workstation, it is personal terminal computing. centralized computing is provided by your enterprise's data center or data center; the cloud computing that everyone is talking about now is completely provided by a third party for computing resources. The three computing modes have different requirements on network connections. In comparison, cloud computing has the highest requirement on network connection performance, followed by centralized computing, and computing on individual terminals. The three computing modes have their own advantages and disadvantages. The key is who it is.

In personal terminal computing, you use your own resources to run applications and connect networks to local hardware. The advantage of this computing is that resources belong to you, as long as you pay a certain fee, it can run for a long time, and because everything is running locally, the network connection requirements are not high. The inconvenience is that you must use it in front of your own computer. This is undoubtedly a huge limit for people with strong mobility.

Centralized computing is used by your IT department to run applications for you using computing and disk resources. It is connected to the company's data center through a LAN, for example, placed in the company's data center.MicrosoftExchangeServer. In this way, all applications are run by the IT department, so you don't have to know much about them, but at the same time you lack more options. You can only apply what the IT department gives you.

Cloud computing, which is currently widely used in the industry, is very different from personal terminal computing and centralized computing. It allows third parties that are completely irrelevant to you to use shared resources to run applications for you, you do not have to worry about the connection between the Internet and a place. For example, if you use Gmail over the Internet, your information is stored in a Google data center that you do not know. The advantage of cloud computing is that you only need to know how to use the application, and you do not have to know everything about it, nor are you subject to computer restrictions, whether you are using a laptop or mobile phone, or any other device that can access the Internet can use the applications you need at any time. However, the dataStorage, Computing, connection, disaster recovery, and so on are outsourced to third parties, so powerful network connections are extremely important.

Therefore, by comparing the three computing modes, whether cloud computing is good or not is indeed a matter of benevolence and wisdom. Whether to choose cloud computing depends on whether it can actually improve your work efficiency. For example, if a large company has its own complete and efficient data center, the use of outsourcing cloud services may not only improve efficiency, but also reduce your work efficiency; however, for many small and medium-sized enterprises, sharing cloud computing resources with other enterprises brings high efficiency. In addition, cloud computing vendors provide different services and have different metrics. If a cloud service provider only provides simple network storage, it is relatively simple. If it is a product for enterprise-level applications, it is very demanding to provide cloud computing data centers, high reliability, fault tolerance, and availability are required.
