Relationship between cloud computing and cloud storage

In the "deep analysis of cloud storage" blog, I introduced in detail the architecture and technical features of the cloud storage system, as well as cloud computing. So what is the relationship between cloud storage and cloud computing? What is the difference between the two.

Cloud computing is the development of distributed processing (Distributed Computing), parallel processing (Parallel Computing), and grid computing, it is to automatically split a large computing processing program into countless smaller subprograms through the network, and then deliver the processing result to the user after computation and analysis by a large system composed of multiple servers. With cloud computing technology, network service providers can process tens of millions or even hundreds of millions of pieces of information within several seconds to achieve the same powerful network services as "supercomputer. For example:

 

 

The purpose of building a cloud computing system is to migrate independent and personalized operations running on a PC or a single server to a large number of servers "Cloud, the cloud system is responsible for processing user requests and outputting results. It is a system centered on Data calculation and processing.

Cloud storage is a new concept that extends and develops in the cloud computing concept. It refers to the use of cluster applications, grid technology, distributed file systems, and other functions, A system that integrates a large number of different types of storage devices in the network through application software to jointly provide data storage and business access functions. When the core of computing and processing in a cloud computing system is the storage and management of a large amount of data, a large number of storage devices need to be configured in the cloud computing system. Then, the cloud computing system becomes a cloud storage system, therefore, cloud storage is a cloud computing system centered on data storage and management.

Compared with cloud computing systems, cloud storage can be considered as a cloud computing system with large storage capacity. Comparison between cloud computing and cloud storage architecture models:

 

 

From the perspective of the architecture model, the cloud storage system has an additional storage layer than the cloud computing system. At the same time, there are many more basic management functions related to data management and data security, the two are identical in the access layer and application interface layer.
