Simple use experience of Hengchuang mainland China vps server

Hengchuang Technology is already deploying data centers in mainland China. The first to launch a vps server is the southwest Guizhou node that was recently launched. It uses KVM as the main virtual architecture and the configuration is also very mainstream. The bandwidth is 1Mbps higher than that of Hong Kong vps. It supports flexible configuration like Alibaba Cloud. You don't need to purchase a data disk, and you can get a system disk for free. It supports Linux and Windows systems. I opened one in early August, but it has been sitting there and not used. To be honest, I don’t know what to use it for now, and there is no business to use it. hey-hey!

Using the common solusvm control panel, there are many operating systems to choose from. There are also system packages compiled by amh in the background. For pure novices, choosing the installation package of the integrated environment can save a lot of time. After all, vps server configuration If not, it is more likely to cause problems.

Discount plan

What this site is trying is the minimum configuration above, which is a 1-core 1G memory solution. The default hard disk capacity is 30G and the default bandwidth is 3Mbps. For ordinary small sites, it can be used for a long time without upgrading after simple optimization. When long-term lag occurs, all aspects need to be upgraded.

5. Summary

In terms of compilation capabilities, the AMH4.2 free version used on this site requires compilation. I have used many cloud servers in mainland China, including Western Digital, Tencent, Alibaba, etc. The compilation time is relatively long, so overall there is no problem in building the website. Mainly It still depends on the stability and speed of the server. This is why many websites choose Tencent, Alibaba, Western Digital, etc. It does not mean how good the performance is. No matter how good the server is, it has poor stability and slow speed, and it is of no use! The IO performance of cloud servers in mainland China is just like this. For high IO performance, it is better to choose a server. After all, except for bandwidth resources, other hardware resources may be used by you alone, hehe! At present, the pricing of Hengchuang in mainland China is relatively reasonable and has a certain cost-effectiveness. After all, there are specialized technical personnel to handle it, which also requires costs.
