The following brings you what is the difference between cloud disk and cloud server system disk. I hope it can give you some help in practical application. Cloud disk involves more things, there are not many theories, and there are many books on the Internet. Today, we will use the accumulated experience in the industry to do an answer.

What is the difference between a cloud disk and a CVM system disk? The system disk of the server is used by the installation system, and the data is cleaned each time the system is reinstalled. In general, it is best not to put the daily data storage on the system disk.

Cloud disks are used to make data disks. They are plug-in independent cloud disks. After the server reinstalls the system, the data on the cloud disk will not be emptied. Usually, the system disk uses the local hard disk, and the data disk uses the cloud disk to expand the capacity, which is convenient for expansion.

Cloud disk is a highly available, reliable, low-cost, customizable network block device that can be used as an independent scalable hard disk of a CVM. It provides block-level data storage and adopts three-copy distributed mechanism to provide data reliability guarantee for cloud servers.

Generally speaking, cloud disks of cloud service providers provide several types of SSD disks, high-performance cloud disks and ordinary cloud disks. Different disk types, performance, features and prices are different. Users can choose according to the requirements of the deployed application.

SSD hard disk: provides high performance storage with low latency, high random IOPS, high throughput and high data security. SSD hard drives are suitable for scenarios that require high performance.

High-performance cloud disk: suitable for small and medium-sized applications with high data reliability and medium performance requirements, as well as small and medium-sized relational database applications such as MySQL, SQL Server, PostgreSQL, etc.

Ordinary cloud disk: suitable for business scenarios with low Imax O load where data is accessed infrequently. The magnetic medium is used as the storage medium, and the three-copy distributed mechanism is adopted to realize high reliable data storage.

SSD disks are more suitable for intensive Igambo scenarios, such as medium and large databases, big data analysis, etc. High-performance cloud disks are mainly used in small and medium-sized databases, Web servers, enterprise office business, log services, and so on, to provide long-term stable IAccord O performance output.

The above is an introduction to the difference between cloud disks and server system disks.
