AliCloud server 4-core 8g Memory configuration performance price list and how to choose? Alibaba Cloud 4-core 8G memory It is a very common ECS configuration and a commonly used configuration model in business. In order to facilitate your selection, Weiaisi Blog intends to explain its detailed configuration, performance, price list and how to choose in this article.
1、 Alibaba Cloud server 4-core 8g configuration performance
The table shows all Alibaba Cloud 4-core 8g models. At present, there are five different models on sale, and the first four models are commonly used models.
The CPU of the burst performance instance is limited to 10%~15% at most;
The shared computing type is called "sharing", which means that there is competition between multiple instances, which will compete for the resources of the hardware host;
Both the enhanced computing network and the computing model are "exclusive" hosts, which enjoy 100% of the system resources without sharing behavior. Compared with the above two models, the performance is more powerful.
2、 How to choose?
The burst performance instance has too many CPU restrictions, which is suitable for services that cannot occupy all CPU resources for a long time. In other words, if you don't know much about it, you'd better not be greedy;
Shared computing has performance competition, but it can also run most common businesses, so it is cost-effective. The same shared instances are not suitable for businesses that occupy a large amount of system resources for a long time;
The computing network enhanced and computing models have strong performance because they can be exclusive. Enterprise level businesses and businesses that occupy a large amount of system resources for a long time can be used without being stuck or unstable. Network enhancement means that it has the ability to receive and send packets of ultra-high network PPS, and the computing type means that the computing performance is stable;
If your business is a common website, blog and the like on the market, the shared computing type can already be satisfied; If the website consumes a lot of CPU, you should choose the computing type. If the website consumes a lot of network, you should choose the computing network enhanced type. Occasionally, there will be a burst like voting, and consider the burst performance instance that is not normally used.
High frequency computing instance I/O optimization, high CPU frequency and computing performance, suitable for high-performance business use.
