Tengxun cloud account purchase: how to choose the region and available area to make the website visit the fastest in China!
For any webmaster, developer, or corporate IT leader, the website's
Access speed
Is the lifeline.
The data shows that every 1 second delay in web page opening time will lose a large number of potential users. Among all the underlying factors that affect the speed of the website, the most core and the most impossible to change through later software optimization is the "region (Region)" of the server"
with
Zone ".
Whether you're just finished

Whether you plan to do a big job or do a multi-cloud backup architecture, as long as your target users are in China, how to choose the location of the computer room is an absolute technical job.
Today's in-depth tutorial is completely disassembled in vernacular:
How to choose the region and available area of tengxunyun in order to make the website visit the fastest in China?
1. Core Concepts: What Are Regions and Availability Zones?
Before choosing the computer room, let's understand these two high-frequency words in one minute, and don't be blind as soon as we come up.
Region: refers to the city where the physical data center of the server is located. For example, Tengxunyun's "Guangzhou", "Beijing", "Shanghai" and "Hong Kong, China". The region is completely independent, the farther the distance, the higher the delay of the network optical fiber transmission data.
Zone: refers to a group of computer rooms with independent power and network in the same city. For example, "Guangzhou District 1" and "Guangzhou District 2". The purpose of introducing the availability zone is mainly to prevent disasters (for example, if the first zone is powered off, the second zone can still be topped).
A big vernacular analogy:> choosing "region" is like choosing which city you open a physical store (Beijing or Guangzhou); Choosing "usable area" is like choosing which street in the city to open a branch. It is the city (region) that determines the speed of users entering the store, while it is the street (usable area) that determines whether the store is safe or not and whether there will be power outages at the same time.
2. tengxunyun's domestic mainstream regional depth evaluation: where your users are, buy the server
The only golden iron law for choosing a territory is:
The closer the geographical distance, the lower the network latency and the faster the speed.
China's vast territory, Tencent Cloud in the core backbone network nodes are heavily deployed. Let's take a look at the distribution and applicable objects of the domestic mainstream region:
1. East China (Shanghai, Nanjing)
Coverage: Jiangsu, Zhejiang, Shanghai, Anhui and other core economic circles.
Speed characteristics: the backbone network of the three networks (telecom, Unicom, mobile) is directly connected, which has a strong radiation capacity for the backbone network in East China and Central China.
Suitable for: e-commerce websites, corporate official websites, and applications for users in Jiangsu, Zhejiang and Shanghai postal service areas.
2. South China (Guangzhou, Qingyuan)
Coverage: Guangdong, Guangxi, Fujian, Hainan and Hong Kong, Macao and Taiwan regions.
Speed characteristics: South China is the core hub of domestic Internet going to sea and internal radiation. The access speed of southern telecom users can basically pull to a very low latency within 10%.
Suitable for: game back end, social
Hand in App, South China Local Life Service Website.
3. North China (Beijing, Tianjin)
Coverage: Beijing, Tianjin, Hebei, Shandong, Northeast three provinces.
Speed characteristics: North users are mainly Unicom users in the world. Beijing computer room has a very good optimization of North Unicom with extremely low delay.
Suitable for: government and enterprise customers, for the north and northeast users of the business.
4. Southwest China (Chengdu, Chongqing)
Coverage: Sichuan, Chongqing, Yunnan, Guizhou, Tibet, Shaanxi and other central and western regions.
Speed characteristics: In the past, the delay of users visiting coastal computer rooms in the central and western regions was relatively high. With the construction of Chengdu-Chongqing backbone network, the southwest computer room has become a natural acceleration station for users in the central and western regions.
Suitable for: Southwest local business, video streaming media, disaster recovery backup for coastal computer rooms.
3. Practical Exercise: The Fastest Selection Strategy for Websites in Different Scenarios
Having defined the geographical distribution, how do we make decisions when we actually buy servers in different business scenarios? Complete
Purchase a Tencent Cloud account
After that, how to choose the region and available area of Tencent cloud to make the website visit the fastest in China? The following is the specific strategy:
Scenario 1: Users are all over the country, and there is no obvious geographical concentration.
If your website is an information station, tool station or national e-commerce for national netizens, should you place the server in Beijing, Shanghai or Guangzhou?
Optimal solution: East China (Shanghai) or North China (Beijing) is preferred.
Reason analysis: From the geographical center of China map and network backbone topology, Shanghai and Beijing are in equilibrium. If the server is placed in Guangzhou, the user access delay in Heilongjiang and Xinjiang in the north may soar to more than 80ms. However, in Shanghai, whether it is going south to Guangzhou, north to Beijing, or west to Chengdu, the delay can be smoothly controlled at about 30-40ms, with the most balanced access speed in the country.
Scenario 2: Specific local business
If your business is a "Shenzhen city water small program" or "Beijing local rental network".
Optimal solution: directly choose the local or the nearest city (Shenzhen choose Guangzhou, Beijing choose Beijing).
Reason analysis: close is justice. Local users in South China usually have a delay of less than 10ms when visiting the Guangzhou computer room. This "second-on" silky experience can greatly improve the conversion rate of users.
Scene 3: The website does not want to record, but requires the fastest domestic access
In China, the purchase of servers in mainland China to build websites must go through a compliant domain name filing. If you are urgent or want to save the cumbersome filing process, the server must be bought outside mainland China.
The optimal solution: the decisive choice of "Hong Kong, China" region.
Reason Analysis: Tengxun Cloud's Hong Kong, China Computer Room is equipped with extremely high CN2 GIA (China Telecom's Next Generation Carrier Network) direct connection for domestic users. This means that although the server is overseas, the delay for Guangdong users to access the Hong Kong server is even lower than that for Beijing servers! The delay of users in East China and Central China can also be maintained at about 40ms, almost equal to that of China.
The speed of the internal double-line computer room is the absolute first choice for free filing websites.
How to choose a 4. zone?
Select the region, the next system will let you choose "available area one", "available area two"... a lot of people here just random point. In fact, the choice of availability zone is directly related to your
Access stability
and
Intranet transmission speed
.
Rule 1: Single machine deployment, choose casually, speed is no difference
If you just buy a server, build a personal blog or small business website with hundreds of IP per day. Then the availability zone 1 or the availability zone 2, the access speed to the user's external network is
Exactly the same
Of it. Because they are all in the same city, the fiber delay within the city is negligible. It is recommended to directly select the default recommendation.
Rule 2: Multi-machine deployment, pursue intranet speed and select "same available area"
If your website architecture includes a lightweight application server/cloud server and a cloud database (CDB):
Core principle: The server and database must be selected in the same Availability Zone.
Reason: If your server is in "Shanghai District 1" and your database is in "Shanghai District 2", although they are all in Shanghai, every time the web page is loaded to the database to read data, the traffic will run across the computer room, which will increase the internal network delay by a few milliseconds for no reason. Put them in the same availability zone, intranet transmission is almost zero latency.
Rule 3: Pursue high availability and select "cross-zone disaster recovery"
If your website is a large e-commerce, or a core enterprise business that does not allow a minute of downtime:
Core principle: Buy two servers, place them in "Availability Zone 1" and "Availability Zone 2" respectively, and mount a load balancing (CLB) in front.
Reason: In this way, even if an extreme lightning strike or power failure occurs in the computer room in Zone 1 one day, the load balancing will instantly cut all traffic to Zone 2, and the website can still be opened in seconds to ensure that the business will never drop.
How to test which region is the fastest before a novice 5. buys a server?
Talk on paper and finally feel shallow. Before paying, is there any way to measure the real speed of your local or target users to each computer room of Tengxun Cloud?
In fact, complete.
Purchase a Tencent Cloud account
After that, we can directly use the ping tool of the system to measure the speed.
Open the command line terminal of the computer (Windows the shortcut key Win R to enter cmd,Mac to open the Terminal).
Enter the test command to view the delay. For example, to test the Hong Kong region, ping linstat.cloud.tencent.com (or use the public speed measurement IP address of each region).
Look at the returned time = XXms. The smaller the number of XX, the faster the speed.
The usual delay comparison table is as follows:
<20ms: extremely silky, basically directly connected to the same province or backbone network.
20ms - 50ms: excellent, normal speed of domestic inter-provincial visits.
50ms - 100ms: generally, there will be zero when the website is opened.
A few seconds of tiny naked eye perception.
> 150ms: compared with the card, if the domestic visit is delayed, you have chosen the wrong overseas region.
Summary: Pit Avoidance List for Speed Pull-up
Want to make your website domestic access speed fly, complete
Purchase a Tencent Cloud account
After that, how to choose the region and available area of Tencent Cloud to make the website visit the fastest in China? Please accept this final selection list:
National access to East China (Shanghai) or North China (Beijing), not the most balanced network.
The local business chooses the nearest city, and the delay within 10ms can make the website really open in seconds.
If you don't want to file, you must choose Hong Kong, China. CN2 direct connection speed will hit other overseas computer rooms.
The server and database of the same website must be in the same available area to avoid the delay across the data center of the intranet.
Understanding the region and the doorway of the available area can not only make you spend every penny on the cutting edge, but also make your website naturally ahead of peers in speed. Hurry up and go to the console to test your optimal region!
