How to choose the Tencent Cloud CVM server region? What is an availability zone?

What are the differences between Tencent Cloud server regions? What is the better choice? The principle of choosing a region is that the closer it is to the region, the lower the network latency and the faster the speed. There are many factors regarding the choice of region. The selection of regional nodes also takes into account the network delay speed, intranet connection, whether registration is required, and price factors in different regions. The availability zone also takes into account factors such as high disaster tolerance and high availability. Tencent Cloud Server Network will explain in detail what cloud server region? What is an availability zone? As well as several factors to consider when selecting regions and availability zones:

Tencent Cloud server region and availability zone

Tencent Cloud region is the regional city where the cloud server data center is located. The closer the user is to the regional node, the lower the network latency and the faster the speed; the availability zone refers to the area where power and network are independent of each other in the same region. Availability zones can be To fault isolation, the significance of the existence of availability zones is to build a high disaster tolerance and high availability architecture.

Note: You should be careful when choosing the Tencent Cloud server region and availability zone, because once the cloud server is created, it cannot be changed. If you buy the wrong region, you can only apply for a refund first and then buy it again. It is too troublesome and you may accidentally return it.

Cloud Server Let’s talk about the four considerations in Tencent Cloud region selection and the three reasons for availability zone selection in detail:

Four major considerations when choosing a cloud server region

The geographical selection of Tencent Cloud servers is mainly based on network delay speed factors, whether registration is required, multi-product intranet interoperability and price:

Factor 1 for regional selection: Consideration of network delay speed

Theoretically, the closer the user is to the data center city where the cloud server is located, the lower the network latency and the faster the speed. Therefore, Tencent Cloud server region selection can follow the proximity principle and select the region closest to the location of the user group.

For users concentrated in North China, choose the Beijing region; for visitors concentrated in South China, choose the Guangzhou region; for users across the country, choose the Shanghai region. In mainland China, with the support of BGP high-speed network, the speed difference is actually so small that users can hardly notice it. However, overseas regions should be carefully considered. There is a huge gap in network latency between international broadband regions. For the Northeastern Asia-Pacific region, Seoul and Tokyo are the first choices; for Europe, Frankfurt and Moscow are the best choices; for the Southeast Asia-Pacific region, Singapore, Bangkok, and Jakarta are the best choices; for the Western United States, Silicon Valley is the best choice, and for the Eastern United States, Virginia is the best choice.

Factor 2 of geographical selection: whether filing is required

Mainland China regions such as Beijing, Shanghai, Guangzhou and other regions require registration. If you do not want to register, you can choose non-mainland China regions such as Hong Kong, the United States, Japan and Singapore.

Factor 3 for regional selection: Intranet interoperability of multi-cloud products

If your application requires multiple cloud servers , cloud databases , load balancing , object storage COS and other cloud products, you must also consider the issue of intranet interoperability. Only cloud products in the same region can use intranet connections. Intranet The connection is low-latency, fast, secure and free.

Regional factor four: price differences in different regions

Tencent Cloud will launch some discounts in newly launched regions. For example, there are currently discounts in Nanjing.

How much is the price difference? Different cloud server configurations have different prices. You can test it to see if it is cost-effective.

The above are the four major considerations shared by Cloud Server Bar regarding the geographical selection of Tencent Cloud Server. Let’s talk about the selection strategy of available zones in detail:

Tencent Cloud Server Availability Zone Selection Guide

Availability zones refer to physical data centers with independent power and network in the same region. Fault isolation can be achieved between availability zones. To put it simply, if availability zone one fails, availability zone two can still run normally. Therefore, the availability zone is designed for high-reliability and high-disaster-tolerant applications.

Instances in the same availability zone have the lowest network latency, and cross-availability zones have higher disaster tolerance. Therefore, whether multiple cloud servers and other instances should be deployed in the same availability zone or in different availability zones, a trade-off must be made between high business disaster tolerance and low network latency.

Tencent Cloud server availability zone selection mainly considers five aspects: single-instance application, disaster recovery considerations, low network latency, price factors, and whether the availability zone is old or new:

Availability Zone Consideration 1: Single Instance Application

Cloud Server Bar encounters users who just purchase a single instance application of a cloud server. In this case, there is no need to worry about the availability zone, just a random availability zone.

Availability Zone Consideration 2: High Disaster Tolerance Considerations

If the business requires high disaster tolerance, then Cloud Server Bar recommends deploying applications in different availability zones. In this way, business failure in one availability zone due to network or power outage will not affect the stable operation of another availability zone.

Availability zone considerations three: business low latency considerations

If it is a business that is sensitive to network latency, it is recommended to deploy the application in the same availability zone because the network latency before instances in the availability zone is lower than that in different availability zones.

Availability Zone Consideration Four: Consideration of New and Old Availability Zone Hardware

The cloud server bar takes the Guangzhou region as an example. The availability zones in the Guangzhou region are named: Guangzhou District 3, Guangzhou District 4, Guangzhou District 6, Guangzhou District 7, etc. According to the naming rules, the later the availability zones are, the newer they may be. The hardware is also getting newer. This is purely a guess of the cloud server. You should have fun listening to it.

Availability Zone Consideration Factor 5: Different Availability Zone Discounts

At present, Nanjing District 1, Nanjing District 2 and Nanjing District 3 under the Nanjing region have discounts. You can choose the cloud server configuration and compare the price differences in person. If the price/performance ratio is high, you can give priority to availability zones with discounts.

The above are factors shared by Tencent Cloud Server Network regarding the selection of Tencent Cloud server region and availability zone. The region is mainly selected from four factors: low network latency, fast speed, proximity, whether registration is required, price factors, and intranet interconnection of multi-cloud products; availability zone Choose from five aspects: high disaster tolerance, low network latency, old and new availability zones, single-instance applications, and preferential prices in availability zones.
