Recently, Wei Aisi's blog found that Alibaba Cloud's cloud computing configuration has changed from a single type of server to an entry-level and balanced performance configuration. This change left many friends unclear. So today, Lao Wei will analyze in detail what the changed cloud computing is and how to choose it.
1、 Detailed analysis
If you plan to purchase domestic ECS to build websites, projects and provide services, Alibaba Cloud Server is the first choice.
You can see that there are two types of servers: entry-level configuration and balanced performance configuration. The entry level is configured as burst performance instances (10% - 15% baseline performance), and the balanced performance is configured as shared and network enhanced instances.
The entry level configuration is divided into three different configurations: 1 core 1G, 1 core 2G, and 2 core 4G;
The balanced performance configuration is divided into 1 core 1G, 1 core 2G, 2 core 4G, and 4 core 8G. Both types are 40G system disks.
From the above introduction, we can see that only the hardware (in fact, the software is virtual) configuration type has changed. The corresponding entry-level configuration price is lower, which is used to distinguish it from the balanced performance configuration.
Other regions and bandwidth remain unchanged.
2、 How to choose?
For these two different configurations, Alibaba Cloud officially explains that the configuration is Alibaba Cloud's fourth generation ECS, in which the entry-level configuration uses burst performance t5 instances, and the performance balancing configuration uses shared and network enhanced instances, with better cost performance. Let's take a look at what is a Burstable instance.
The burst performance t5 instance is an instance that can meet the burst CPU performance requirements. Each t5 instance has a benchmark CPU computing performance, and will continuously obtain CPU credits at the specified speed according to the instance type. Once each t5 instance is started, it will start to consume points to meet the demand. When the actual working performance of the instance is higher than the benchmark CPU computing performance, it will consume more CPU credits to improve the CPU performance and meet the work requirements. The t5 instance can seamlessly improve CPU computing performance without affecting the environment or applications on the instance.
That is to say, the t5 instance is suitable for scenarios where the CPU is not constantly under high pressure, but the computing performance needs to be improved occasionally to complete the workload, such as lightweight Web servers, development and test environments, and medium and low performance databases.
Weiaisi Blog also heard some webmasters with large service volumes complain that the ECS of sudden performance instances is easy to get stuck, so it said that sudden performance instances cannot be used for applications with large load, and are suitable for running production environments with small traffic and load, such as personal websites, such as enterprise stations and personal blogs with small traffic. If your website, project and service want to operate for a long time and the traffic and load will increase in the future, you should consider the balanced performance configuration. There will be no bottleneck in CPU.
The difference between the two can also be seen from the price. In the ECS field, the performance gap caused by the price difference is still obvious. The most cost-effective AliCloud cloud server for all is the balanced performance configuration. You can buy an entry-level configuration to play with at the initial stage of training. Later, you will need to use the balanced performance configuration when you officially start a station, and you can upgrade the configuration smoothly in the future.

After the above detailed analysis and the knowledge of how to select, I believe you also understand how to select AliCloud servers after the configuration change of AliCloud national cloud computing. I hope this article can help you to select your own AliCloud servers.
