云计算技术实现需要哪些(云计算包括哪些技术方面)

The core technologies of cloud computing include: virtualization, distributed file system, distributed database, resource management technology, energy consumption management technology, information security, etc.

Virtualization is one of the most important core technologies of cloud computing. It provides infrastructure-level support for cloud computing services and is the main driver for ICT services to rapidly move towards cloud computing. force. Many people have misunderstandings about cloud computing and virtualization, thinking that cloud computing is virtualization.

But in fact, virtualization is only an important part of cloud computing, but it cannot represent all cloud computing. The biggest benefit of virtualization is to enhance the elasticity and flexibility of the system, reduce costs, improve services, and improve resource utilization efficiency. From a performance perspective, virtualization is divided into two application modes.

The first is to virtualize a powerful server into multiple independent small servers to serve different users. The second is to virtualize multiple servers into a powerful server to complete specific functions. The core of both models is unified management, dynamic allocation of resources, and improved resource utilization. In cloud computing, these two models have many applications.

Distributed data storage technology, by storing data in different physical devices, can achieve dynamic load balancing, automatic takeover of failed nodes, high reliability, high availability, Highly scalable.

Because in a multi-node concurrent execution environment, the status of each node needs to be synchronized, and when a single node fails, the system needs an effective mechanism to ensure that other nodes are not affected. This model not only gets rid of the limitations of hardware devices, but also has better scalability and can quickly respond to changes in user needs.

Using multiple storage servers to share the storage load and using location servers to locate storage information not only improves the reliability, availability and access efficiency of the system, but is also easy to expand.

In recent years, various technologies and products such as virtualization, distributed data storage, data management, and information security have developed vigorously, promoting cloud computing technology innovation. It not only monopolizes the delivery model of traditional ICT systems, but also changes the way information is provided. The traditional business model is quietly changing. So, what is the core technology of cloud computing?

Virtualization technology: one of the most important core technologies. Providing infrastructure-level support for cloud computing services is the main driving force for ICT services to rapidly move towards cloud computing.

Distributed data storage technology: Store data in different physical devices, getting rid of the reality of hardware devices. At the same time, it has better scalability, can process large amounts of data faster and more effectively, and better handle changes in user needs.

Large-scale data management: Cloud computing must not only ensure the storage and access of data, but also perform specific retrieval and analysis of large-scale data. Data management technology must be able to effectively manage large amounts of data.

< p>Programming mode: Cloud computing aims to simply distribute powerful server computing resources to end users through the network, while ensuring an efficient, simple, and fast user experience. In this process, the choice of programming mode is very important.

Information security: In cloud computing systems, security involves network security, server security, software security, system security and other levels.

Cloud computing platform management: requires efficient allocation of a large number of server resources , has better cooperation capabilities, facilitates the deployment and opening of new services, quickly discovers and recovers system failures, and achieves reliable operation of large-scale systems through automated and intelligent means.

The five key technologies of cloud computing are as follows: cloud computing platform management technology, distributed computing programming model, distributed massive data storage, massive data management technology, and virtualization technology.

1. Cloud computing platform management technology: The platform management technology of cloud computing systems can enable a large number of servers to work together, facilitate business deployment and activation, and quickly discover and recover system failures.

2. Distributed computing programming model: Cloud computing adopts a simple distributed parallel programming model Map-Reduce. Map-Reduce is a programming model and task scheduling model. It is mainly used for parallel operations of data sets and scheduling of parallel tasks.

3. Distributed massive data storage: Cloud computing systems use distributed storage to store data and use redundant storage to ensure data reliability. The redundant method ensures low cost through task decomposition and clustering, and uses low-end machines to replace the performance of supercomputers. This method ensures the high availability, high reliability and economy of distributed data, that is, storing multiple copies of the same data. .

4. Massive data management technology: The data management technology in cloud computing systems is mainly Google's BTsT~lO data management technology and the open source data management module HBase developed by the Hadoop team.

5. Virtualization technology: refers to the fact that computing components run on a virtual basis rather than a real basis. It can expand the capacity of hardware, simplify the software reconfiguration process, and reduce the overhead and related costs of software virtual machines. Support a wider range of operating systems.
