This article will explain in detail what to choose for CVM images, and the content of the article is of high quality, so the editor will share it with you for reference. I hope you will have some understanding of the relevant knowledge after reading this article.

An image is a template for CVM software configuration (operating system, pre-installation programs, etc.). The template includes a specific operating system and running environment, and sometimes additional pre-installed applications. Therefore, if you choose to enable the image, you can obtain a system environment or software consistent with the instance, so as to avoid complex cloud configuration problems.

Cloud Mirror is a technology for business continuity, disaster recovery and backup, that is, copies of server data created in the cloud, mainly used to create a fault-tolerant and redundant server computing infrastructure.

Take a CVM image as an example. In addition to backup and disaster recovery, a cloud image can also be used for load balancing by providing the same data for quick download to remotely connected users.

In practical application, because the cloud image integrates the server instance system environment and various pre-installed software functions, and the cloud image is used with the server, users only need to carry out a simple operation to easily realize the business on the cloud. Typical application scenarios of cloud images, such as native system installation, software packaging and deployment, service batch customization, and so on.

Currently, all CVM products support custom image feature, which allows users to make images of existing CVMs and use them when business expansion needs to purchase new hosts, thus avoiding the hassle of repeatedly configuring the host environment.

After the custom image is successful, the user will automatically become one of the options for the operating system list interface when purchasing a new host or reinstalling the system. Currently, cloud images are not supported for use across data centers and clusters. If you need them, you can copy them through the image copy feature (because the image files are usually large, the replication time may be relatively long, depending on the data size).

So much for sharing about what to choose for CVM images. I hope the above content can be helpful to you and learn more. If you think the article is good, you can share it for more people to see.
