Alibaba Cloud servers are divided intoAlibaba Cloud entry-level serverandAlibaba Cloud Enterprise ServerThere are two different categories. The so-called entry-level server mainly refers to the entry-level server of burst performance instance T5;Enterprise class servers, mainly computing servers and exclusive servers above.Faced with these two servers with different configurations, I don't know how to choose them. If I choose the wrong server, I can't meet the demand or I waste money.Weiaisi Blog explains in detail the difference between Alibaba Cloud entry-level servers and enterprise level servers and how to choose them through this article.
1、 The difference between entry-level and enterprise level servers
1. Alibaba Cloud entry-level server
It mainly refers to the burst performance instance 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.
At present, starting from Alibaba Cloud computing servers, 2-core 4G memory configurations 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.

The entry-level server has CPU performance limitations while the enterprise server does not. It can fully enjoy all the resources of the system.Stable and fast means enterprise class servers.Not only enterprise users can use it, but also individual users can use it. You don't need enterprise authentication, and you can pay for it.The preferential prices in the above table are for new users to purchase Alibaba Cloud products for the first time.The 2-core 4G memory configuration can cope with the business with tens of thousands of PV of daily access, and has a high cost performance ratio.
If you are limited to testing code and business, beginners can learn server knowledge and occasionally engage in an activity. For lightweight business, you can consider entry-level servers, which are cheap and easy to use.If you plan to operate business 24 hours * 365 days, you should choose enterprise class servers.Stability and speed are the foundation of enterprise class servers.
In general, the difference between entry-level servers and enterprise level servers is obvious. The selection reference factors are mainly based on business needs and prices.For example, the network business of small and medium-sized enterprises must choose enterprise class servers. At this time, you can't care too much about the cost.However, if you want to build a personal blog or small website and don't want to spend a lot of money to buy an enterprise class server, it is also good to consider sharing servers.
If you are just starting a personal blog, you can try to share basic instances with Alibaba Cloud. The configuration, price and purchase links of shared instances are for your reference.The characteristic of shared server is that multiple chickens share the system resources of hens, and there is resource contention among them.In plain English, it is better than the burst performance instance t5, but not as good as the enterprise class server.
