For novices, the name of the server type has always been a "mystery", a puzzle.When Weiaisi Blog first came into contact with Alibaba Cloud, when faced with so many different types of server names, it was a crash in my heart.I am just a little white. You gave me so many names, not to mention the difference. You also need to match different business scenarios with these instance types one by one. As a budding new person, Old Wei's heart was saying no.However, with the rapid development of cloud computing, more and more people have begun to contact and use ECS. As a veteran, Lao Wei has the obligation to share the details of the summary differences and selection of different host instance types of Alibaba Cloud Server.
Alibaba Cloud servers are divided into entry-level, general-purpose, computing, memory, big data, local SSD, high frequency computing, GPU, FPGA, elastic bare metal and other types.Today, what Lao Wei wants to talk about in detail is the entry-level, general purpose and computational models that are applicable to most businesses.The other types of hosts are relatively less common.
1、 Entry level includes burst performance instance t5 instance and shared instance
1. Burst performance example t5.Low performance, cheap price.
Performance: CPU availability is limited to 5%~10%.That is to say, whenever the CPU utilization reaches this figure, it is also the highest peak, and can no longer increase.At this time, the business needs are constantly requesting more CPU resources. What we see at the front desk is that the business will continue to get stuck and there will be no response for half a day.
Price: Compared with the enterprise level, the entry-level burst performance instance t5 is very cheap, and it will be exciting to see.
Scope of application: lightweight business, personal blogs with low traffic, small websites, unexpected activities and promotion levels, and other appropriate business scope.
There is a maximum limit of 10% - 15% performance baseline for CPU, and the price is better.New and old users can buy it. One order is limited, and the original price will be restored from the second order;The longer the time is, the more favorable the price is. New users can buy 3 sets.
Lao Wei has written a lot of explanations, research and explanations for this model before. For interested students, please see the following related articles:
Including computing network enhanced and general-purpose servers
1. Look at the picture above, there is a computing network enhanced instance, which is also a kind of computing server. The network performance is relatively strong.It is also the main model of Alibaba Cloud.If your business requires high stability and speed, this model is highly recommended.
Performance balancing configuration, unlimited CPU performance, higher cost performance

Universal servers appear in Alibaba Cloud enterprise server promotions.Starting from Alibaba Cloud computing servers, the configurations of 2-core 4G memory and exclusive models are available for enterprise servers.
Performance: CPU can operate under 100% long-term full load.Because you can enjoy 100% of the system resources exclusively, there is no such situation as stuck.
Price: It is a little expensive compared with the sudden performance instance.
Scope of application: small and medium-sized individuals, industry websites, small and medium-sized enterprise websites, etc.

1. The entry-level burst performance instance t5 and shared instance are applicable to those personal blogs and small websites.Among them, the burst performance instance has a CPU peak limit of 10%, so Lao Wei does not recommend selecting it.Unless you know how to optimize or meet business needs.Generally speaking, it is appropriate to start from shared instances.
2. If you use the Avada theme, The 7 theme, and the newspaper theme, Mr. Wei strongly recommends that you purchase the computing network enhanced and universal instances.This kind of theme itself consumes memory and system resources, so using these two models will not get stuck.
Enterprise level websites require high stability and are easy to use;
Medium and large websites with large daily traffic also need to use these two models to meet business needs.
3. After talking about the model, I talked about the configuration.Just starting blogs and small websites can use 1 core 2G, but they can be upgraded later if they are not enough;For enterprise level websites and the topics mentioned above, it is appropriate to use a 2-core 4G configuration.
In short, you can choose your own match if you understand it. If you really don't know how to choose, you can also ask Lao Wei on the right side.
