Are all cloud desktop solutions that save electricity bills all wrong?

As a senior cloud computing IT person, customers often ask such questions: Does the cloud desktop save electricity?

Many people will say that the cloud desktop will definitely save electricity, but this is also wrong.

Let me tell you what this is all about.

As we know, in general, cloud desktop consists of server, cloud terminal and cloud desktop software. In this case, the cloud desktop will save more power than using a PC. The power consumption of intelligent cloud terminal is low, only 2.2W under ARM architecture, and only 25W even under X86 architecture. Together with a server of 1000W, it is calculated according to 100 users and 100 200W desktops under traditional PC.

Secondly, let's calculate the electricity bill for 100 office computers 1 year. The power consumption of traditional PC is generally around 150W. Annual electricity charge150w/1000 *10h * 250 days * 65430 days. 000 yuan. The average power consumption of cloud desktop in Ye Zhi is 6.5W (200W server, 48 virtual machines), which is 4.3% of that of traditional PC. Ye Zhi Cloud Desktop: 45,000 yuan * 4.3% = 1935 yuan. Overall, the cloud desktop is still relatively power-saving.

Of course, there is another situation, that is, if the cloud desktop is composed of server+traditional old PC+ cloud desktop software, it will not save electricity. As we know, cloud desktop not only has the characteristics of cost saving and maintenance, but also has the characteristics of using the old one, that is, using the reused PC to connect the virtual desktop of the server. All applications and data are running on the server, and the old PC only serves as a bridge to connect the server, and there is no other operation. In this case, the cloud desktop will not save electricity.

When we talk about cloud desktop power saving, we mean that in the case of using low-power products such as cloud terminals, mobile phones or PCs, if the original old PC reuse scheme is adopted, the effect of saving electricity can not be achieved.
