Alibaba Cloud Global Fourteen Node Evaluation Analysis and Server Region Selection Guide

With the continuous development of Alibaba Cloud, there were only a few dots on the picture about the data center on the homepage, but now a lot of them have been deployed at home and abroad There are so many data centers, which led to the editor, I was really miserable in order to organize this article. How can there be so many data centers!

So the question arises again, what is the difference between so many data centers? How should data center selection be considered? How to buy the best deal?

What is an Alibaba Cloud server regional node?
Generally speaking, Alibaba Cloud products are divided into regions (Regions) and availability zones (Zones). The main difference between regions is distance. The distance between different regions is relatively long. The cost of optical fiber connection is high, so the intranet between regions is also blocked. For example, East China 1 Hangzhou, North China 1 Qingdao. The second consideration is the needs of users. For example, East China 1 Hangzhou and East China 2 Shanghai are not far apart, so deploying services in one place alone will not have a great impact, but with the increase in user demand, it is necessary to set up a separate service. One East China 2 Shanghai District.

Availability zones are different data centers in the same region. Because the distance in the same city is very short, it is feasible to realize intranet connection through optical fibers. The connection between different availability zones in the same region is about 1ms. Time. Then we will introduce the regions separately. As of the time of writing, Alibaba Cloud has the following regions:


How to choose a cloud server region node
Alibaba Cloud can take all the subdivision application scenarios in many regions in China. For example, if it is For applications that are sensitive to delays such as the game industry, the domestic East China 1-Hangzhou is mainly used to serve users in Zhejiang Province, where Hangzhou is located, and even in the entire East China region. It is completely possible to use one Huadong 1 to serve the entire Chinese and even some Asian users.

For overseas regions, then it is necessary to squeeze every point of value like a sponge. For example, Southeast Asia 1-Singapore can be used to serve users in the entire Southeast Asia and South Asia, and it is better like East America 1-Virginia. That is, it can cover the whole of North America, and it can also serve Latin American countries like Brazil and Argentina, and it is not far from Europe. It can also be used to serve European users.

The second is whether the services in the region are complete. For example, if I do high-definition video rendering and want to purchase GPU machines from Alibaba Cloud to achieve fast rendering, then we must consider whether there are related services in the selected region.

In addition, it is necessary to check relevant news, whether the network in the selected region is stable, whether accidents often occur, whether the network service provider often does cutting, etc., but these are all small probability events (other clouds will also encounter network accidents), Even if there is an accident, Alibaba Cloud will still pay for it. If it is not a service that is very sensitive to SLA, it can be ignored.

Finally, consider the availability zone. Generally speaking, the larger the letters of availability zone A, B, and C, the newer the data center, the newer and better the hardware selected, and the lower the probability of the latest accident in the underlying architecture. .


How to buy products from different regions at the best price?
As a budget-conscious editor, of course, I want to tell you how to make good use of every penny, so how to buy products from different regions at the best price?
After the Yunqi Conference is over, generally speaking, during the larger Yunqi Conference (such as the Hangzhou Yunqi Conference in October), some concession policies will always be announced, and the overall price will not be too expensive.
Waiting for Double 11, Double 11, the festival of buying, buying and buying, Alibaba Cloud will not pull it down. Generally speaking, the annual payment and multi-year payment of related products on Double Eleven, and then there are still many coupons to grab. When to buy.
When the new region is open for purchase, if I remember correctly, there is a 20% discount margin when China North 3 is just launched, so waiting for a new region to launch is also full of profits!
Pay attention to the Yunqi community, developer forums, and related new media public accounts to grab vouchers, and participate in more community and new media activities. At present, there are relatively few people participating in the interaction in the developer forums in the three blocks, and the vouchers in the prizes are really too much. It's easy to take, it's real money, this welfare editor generally doesn't tell others.

Alibaba Cloud Server Data Center Evaluation
This evaluation only represents personal test results, which may be affected by many factors, such as network service providers, new optical fibers to improve the network, routing switching and cutting, and line fluctuations caused by the peak network bandwidth. Time-sensitive users are best to test by themselves to avoid misleading. Alibaba Cloud ECS Server Region Selection Evaluation: North China 1
