What this article shares with you is a brief introduction to cloud storage. The editor thinks it is very practical, so I hope you can get something after reading this article. Let's take a look at it with the editor.

Cloud storage is a new concept extended and developed in the concept of cloud computing in recent years.

Cloud storage is based on cloud computing concept

Cloud computing is the development of distributed processing, parallel processing and grid computing, which automatically splits huge computing programs into countless smaller subroutines through the network. then a huge system composed of multiple servers is calculated and analyzed to transmit the processing results back to the user.

The concept of cloud storage is similar to cloud computing, it refers to a large number of different types of storage devices in the network work together through application software through functions such as cluster application, grid technology or distributed file system. A system that jointly provides data storage and business access functions.

The difference between traditional storage and cloud storage

The traditional enterprise storage basically adopts centralized storage, the storage system is composed of disk array cabinet and storage network, and the disk array cabinet consists of disks and controllers, which is connected to the server through the storage network. the sharing of storage is limited to the disk array cabinets, and disk cabinets mainly play the role of backup. The small scope of storage sharing and high reliability requirements make the enterprise storage cost very high.

The storage of cloud computing is to manage the disks within each server through distributed software to form a storage resource pool, so it can be fully distributed and globally shared. that is, a server can use the storage resources on any other server in this data center to achieve the purpose of full sharing, dynamic allocation of resources, improve resource utilization, and greatly save costs.

And because of the scale of this large cluster, cloud storage can reach the level of P bytes (1000T) and E bytes (1000p), which can meet the storage requirements of "high capacity and low cost". This is why many large Internet companies adopt this model; for traditional storage to cloud computing can also use the same model, need to work on the software.

Reliability of Cloud Storage Technology

The performance and reliability of cloud storage are solved by multiple backups. Because the performance and reliability of hard disks built into servers are generally low, in order to improve performance and reliability, three copies of data are generally stored on different servers and 5 copies of critical data are stored. While improving reliability, applications can read data from different servers at the same time to improve performance.

The above is a brief introduction to cloud storage, and the editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
