About the meaning of cloud computing and cloud storage

1. Cloud computing is the increase, use and delivery model of Internet-based related services, which usually involves providing dynamic and easily scalable and often virtualized services through the Internet. The resources of the Internet are a metaphor for the network and the Internet.
2. Cloud storage is a new concept extended and developed from the concept of cloud computing. It refers to the use of cluster applications, grid technology or distributed file systems and other functions to integrate a large number of data in the network. A system in which various types of storage devices jointly provide data storage and business access functions to the outside world.
3. Cloud computing consists of a series of resources that can be dynamically upgraded and virtualized. These resources are shared by all cloud computing users and can be easily accessed through the network. Users do not need to master cloud computing. Technology only requires renting cloud computing resources according to the needs of individuals or groups.
4. Cloud storage is a new concept that is an extension and derivative of the concept of cloud computing. Cloud computing is the development of distributed processing, which automatically processes huge computing processes through the network. It is split into countless smaller subroutines, and then handed over to a huge system composed of multiple servers. After calculation and analysis, the processing results are returned to the user.

What are the key technologies of cloud computing_What are the key technologies of cloud computing

The key technologies of cloud computing mainly include data storage technology, data management technology and programming model.

Data storage technology

Cloud computing generally uses distributed storage to store data. At the same time, with the support of redundant storage, it can improve the reliability of data storage. This allows data to be stored in multiple copies at the same time, further improving data security. In the existing cloud computing data storage, data is mainly stored through two technologies, namely Google Filesystem (non-open source GFS) and Had00pDistributedFileSystem (open source HDFS). The above technology is essentially a large-scale distributed file system that provides required services to customers with the support of computer groups.

Data management technology

Since the cloud platform carries a large amount of user information, it places high requirements on the data management function of the cloud platform. With the support of cloud computing, cloud platforms can also perform large-scale data calculation and analysis while storing large amounts of data. Its representative technology is BigTable data management technology, which manages user data through column storage.

Programming mode

In existing cloud computing, programming is mainly performed through the Map-Rece programming mode. Programs written in the Map-Rece programming mode have good compatibility and strong fault tolerance. Once there is a problem with the server working node, the problematic node can be directly shielded and the running program can be transferred to Run on other servers, so as to ensure the normal progress of data processing.

Cloud computing is a new computing model. Its main feature is to perform calculations through dynamically scalable virtualized resources based on the existence of the Internet. With the rise of cloud computing, world-famous IT companies such as Microsoft and Google have joined in the development of cloud computing, which has significantly promoted the development of cloud computing. In recent years, our country has also paid more and more attention to the development of cloud computing technology. For example, Tsinghua University and Google have cooperated to propose a cloud computing academic cooperation plan. This plan will bring a greater scope of use to cloud computing. At the same time, It also promotes the development of cloud computing technology in our country. According to relevant data, cloud computing will account for more than 30% of IT costs in the future. With the vigorous promotion of major IT companies, cloud computing will have a broader space for development.

Cloud computing technology is still in the development stage, and continuous improvement on the existing basis will provide it with a broader development space. Of course, there are still some problems with current cloud computing technology. In particular, due to the large scale of data processing in cloud computing data centers, it is easy to cause equipment to heat up and have a certain impact on the equipment. In addition, there are also different standards for cloud computing interfaces. Further unification is needed. In short, cloud computing technology has brought great convenience to our lives and provided good technical support to all walks of life. The development of cloud computing technology will become the mainstream trend of IT information technology.
