1. Keep your needs in mind

In the final analysis, CVM is for your business, so first of all, you need to identify your needs for CVM, compare and evaluate various features, such as virtualization features, network isolation and root permission isolation. Pay attention to managing and monitoring resource management functions such as processor, memory, disk Imax O performance, storage limits, and so on. After determining that a platform can meet the specific criteria of your business, evaluate the cost.

2. Network line selection

According to the network line connected to the data center, domestic CVM provides single-line / dual-line bandwidth such as China Telecom and China Unicom. It is recommended to choose dual-line. This is true even if your business is mainly aimed at the local customer base. Because the broadband usage of local customers is not uniform, even in northern China, there are a large number of telecom users. In order to meet the access needs of customers of different network operators, it is recommended to choose dual-line, double-IP or multi-line.

3. Hong Kong node is recommended

According to the difference of deployment area, many service providers provide a variety of nodes for you to choose from, such as China, Hong Kong, South Korea, the United States and so on. Domestic nodes must be registered. American CVM is slow to connect to China, so if your business is aimed at customers in the Asia-Pacific region, you personally recommend Hong Kong nodes.

The Hong Kong node, which generally adopts BGP international multiline, supports high-speed visits to Chinese mainland and the Asia-Pacific region, and enjoys highways in both the north and south of the mainland. More importantly, Hong Kong CVM is record-free and ready to use, and your business can be launched as quickly as possible to take advantage of the market. If your customer base is mainly distributed in North America and Europe, it is recommended to use a US CVM.

4. Performance test of CVM

Before purchasing a CVM, it is recommended to perceive the performance of the CVM through performance testing (in general, many cloud service providers provide test models, free trials, 3-day unconditional refunds, etc., all of which can be used for performance testing).

You can initially grasp the network connection speed and quality of the CVM by performing ping, Tracert route tracking and website speed measurement tools on the test IP. Test disk performance by HD Tune and other tools.

In short, we need to test the stability, network stability and software compatibility of the CVM, including whether the CVM is down, whether it can recover damaged data, whether it has * * protection, network delay and packet loss rate, whether the software installation and operation is normal, and whether the software data is compatible.

Finally, we would like to remind CVM users that although CVM has mechanisms such as multiple data copies and snapshot backups, we cannot discard the traditional regular local backup habits.

Because no matter how stable the cloud platform is, there is no guarantee that it will be 100% fault-free. Once the infrastructure of the cloud platform fails, the consequences may be devastating. It is our duty to protect the results of our efforts and the last line of defense to prevent the loss of critical business data by backing up our own website data and downloading it to the local storage.
