This article will explain in detail how to expand the virtual host database when it is not enough, 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 a certain understanding of the relevant knowledge after reading this article.

As we all know, when the number of users reaches a certain level, the website will encounter database pressure. You know, if the performance of the database is affected, the user experience will be greatly reduced. Especially now there are most dynamic websites, about 20% of the data accessed by a business will interact directly with the database.

If you do not expand the capacity of the virtual host database, it is recommended to migrate to the CVM. CVM generally uses distributed storage, and the resources can be expanded flexibly.

For example, a platform has a large V, if it produces interaction, it will read a small part of the data first, which will reduce the pressure on the database and improve the access speed of the whole site. In the way of using cache, distributed cache server is generally used, while remote distribution uses cluster server to cache data, which can be expanded dynamically even if there is not enough memory.

When data access is mitigated, the application request connection needs to be optimized. In general, during the peak period of website access, the application server will become a bottleneck. For the website, it can increase the load pressure on the server, and it can also continuously improve the server performance in the same way, thus making the system more scalable.

According to different needs, users of CVM can freely choose vCPU, memory, data disk, bandwidth and other configurations, and can also downtime and upgrade vCPU and memory within 1 minute to support the continuous development of the business. A CVM can be mounted to a cloud disk. A CVM can mount up to 10 cloud disks and accumulate 40TB to meet the storage needs of user big data.

About the virtual host database is not enough how to expand the capacity to share here, I hope the above content can be of some help to you, can learn more knowledge. If you think the article is good, you can share it for more people to see.
