Alibaba Cloud t5 instance with burst performance should be carefully used for long-term site establishment and Windows remote desktop

AliCloud cloud computing for all Currently includes entry-level configuration（ Burst performance t5 instance ）And performance balancing configuration (shared n4 instances and computing network enhanced instances). The price difference between the minimum entry-level configuration and the minimum performance balancing configuration is about 100 yuan. For ECS, this gap is large, which means that there is also such a gap in performance. After Weiaisi Blog's own trial and netizens' actual use experience, if you plan to build a website or do a project for a long time, Lao Wei does not recommend that you buy the entry-level configuration of AliCloud cloud computing for all.

My friend, who works in eBay and Amazon e-commerce, is a novice to ECS for the first time. Because he doesn't understand the performance and is greedy for bargains, he bought an Alibaba Cloud cloud computing entry-level configuration server, and opened an IE browser during use, Internet Explorer will get stuck when it opens two more pages. In serious cases, it will frequently crash when it opens four pages. After a period of use, I feel I can't stand this kind of crash. I come to ask Old Wei what the situation is and whether he can continue to use it. After searching Alibaba Cloud related information, Lao Wei found out why.

The entry level minimum configuration 1-core 1G 40G system disk is 293 yuan/year, and the performance balanced minimum configuration 1-core 1G 40G system disk is 394 yuan/year. The hardware configuration is exactly the same, but the 30% price difference is that the former limits the CPU utilization ratio of 10%~15%. The burst performance t5 instance (entry level configuration) is based on the benchmark CPU computing performance, The integral value is obtained by the cumulative weight of the difference between the actual CPU utilization rate and the benchmark CPU utilization rate.

To do eBay and Amazon online, you need to add goods and reply to messages in the Windows server. Every day, you have to work with the remote desktop and the Internet Explorer web page open. After the Windows system is powered on, the system itself will occupy at least 20% of the CPU resources. At this time, you can open Internet Explorer and open several more windows at the same time, The CPU utilization rate is naturally high. The newly purchased t5 instance with burst performance will give a certain amount of CPU points by default. In the initial period of time, the remaining CPU points can be used normally. Soon, when the CPU points are exhausted, the CPU performance will be limited to the benchmark (no more than 10%~15% of the CPU utilization rate), which will naturally cause a jam, serious panic and other situations.

Therefore, the t5 instance is suitable for scenarios where the CPU is not used under continuous 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. Remote desktop operations such as ebay and amazon are not suitable for this type of host.

I also heard from another friend that he bought a 2-core 4G burst performance t5 instance and used the CentOS system to bind a total of six enterprise websites, one of which is the avada template (at the beginning, two avada template websites were bound, but later, when there was a jam, only one was left). Because the enterprise website itself does not have much traffic and resource consumption, it can still operate normally.

In order to ensure the normal operation of the production environment and business, which type of ECS should be selected? Lao Wei recommends selecting a performance balanced configuration, which is matched with Alibaba Cloud 1000 yuan voucher exclusive to this blog when purchasing Click me to get it A hundred products worth 50 yuan. Or it is recommended to use high-performance cloud servers such as general-purpose g5 and computational c5.

The shared n4 instance and the computing network enhanced instance in the performance balancing configuration can fully meet the needs of the conventional production environment. There is no limit on CPU utilization, and all the normal performance of the CPU is fully exerted. There will be no more stuck, dead, etc.

After listening to Old Wei's analysis, my friend also understood the difference between the two configurations and immediately applied for a refund. Alibaba Cloud calculates the refund fee by day based on the service time, so that part of the amount can be recovered, and the balanced performance configuration can be repurchased for use in the production environment.

I remember that when the nationwide cloud computing just launched these two configurations, Lao Wei wrote an article recording Detailed analysis and selection of Alibaba Cloud national cloud computing changes to entry-level and balanced performance configuration Many friends may not see or understand the difference in the production environment after reading this article. I hope friends in need can read this article again and write it clearly.

After solving this problem, Lao Wei recorded the whole process. Usually, netizens and Lao Wei complained about the slow speed of Alibaba Cloud servers and their problems. Later, they consulted several friends who had purchased and used the entry-level configuration of Alibaba Cloud cloud computing for all people (not just because of greed), I hope it can help you find a suitable host for your own use in how to choose different configurations of AliCloud cloud computing.
