Cloud storage is a cloud computing system with data storage and management as its core. Its structural model generally consists of four layers: storage layer, basic management, application interface and access layer.

Characteristics of cloud storage:

1. Ultra-large scale

Cloud storage has a considerable scale, and the data stored in a single system can reach hundreds of billions. , even trillions.

2. High scalability

First, the system itself can easily dynamically increase server resources to cope with data growth; second, system operation and maintenance is scalable, which means that as the system scales The increase does not require the addition of too many operation and maintenance personnel.

3. High availability and usability

Through technologies such as multi-copy replication and automatic fault tolerance of node failures, cloud storage provides high availability and reliability.

4. Security

Cloud storage internally ensures security through user authentication, access permission control, secure communication (HTTPS, TLS protocols) and other methods.

5. Transparent service

Cloud storage provides services in the form of a unified interface, such as RESTFUL interface. Changes in back-end storage nodes, such as adding nodes and node failures, are transparent to users.

Extended information:

Low cost is an important goal of cloud storage. The automatic fault tolerance of cloud storage allows it to be built using ordinary PC servers; the versatility of cloud storage greatly improves resource utilization; the automated management of cloud storage greatly reduces operation and maintenance costs; the data center where cloud storage is located can be built on the power grid. resource-rich areas, thereby significantly reducing energy costs.
