4. Virtualization technology 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 driving force for ICT services to rapidly move toward cloud computing. It can be said that without virtualization technology, there would be no implementation and success of cloud computing services.

5. The core idea of ​​cloud computing is to uniformly manage and schedule a large number of computing resources connected by the network to form a computing resource pool to provide on-demand services to users. "Cloud" is a network that provides resources.

What technologies are there in cloud computing?

1. The key technologies of Google cloud computing mainly include: Google file system GFS, distributed computing programming model MapReduce, distributed lock service Chubby and distributed structure Globalized data storage system BigTable, etc.

2. As of 2018, the main application technologies of cloud computing are as follows: Cloud security is a new term evolved from "cloud computing".

3. Resource management technology. Cloud computing requires the processing and analysis of distributed and massive data. Therefore, data management technology must be able to efficiently manage large amounts of data. The platform management technology of cloud computing systems requires the ability to efficiently allocate a large number of server resources so that they can work better together. Energy management technology.

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

What are the core technologies of cloud computing?

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

The core technology of cloud computing system: parallel computing. Parallel Computing refers to the process of using multiple computing resources to solve computing problems at the same time. It is an effective means to improve the computing speed and processing power of computer systems.

For example, if you plan to work in the field of big data and nosql, you need to master Hadoop, Hbase, Cassandra and some theories (CAP, Base, etc.); if you want to work on cloud platforms (Iaas, Paas) , you can study virtualization technology (kvm, hyper-v, etc.), OpenStack, esxi and other technologies.

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

Resource management technology. Cloud computing requires the processing and analysis of distributed and massive data. Therefore, data management technology must be able to efficiently manage large amounts of data. The platform management technology of cloud computing systems requires the ability to efficiently allocate a large number of server resources so that they can work better together. Energy management technology.

The key technologies of cloud computing include the following directions: Virtual machine technology Virtual machine, that is, server virtualization, is an important cornerstone of the underlying architecture of cloud computing.

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

Function: Relatively simple cloud computing technology has been widely used in today's Internet services. The most common ones are online search engines and web mailboxes. Search engine At any time, as long as you use a mobile terminal, you can search for any resources you want on the search engine, and share data resources through the cloud.

The key technologies of CloudComputing are: FO software development method. This is a software development method that is further abstracted on top of "object-oriented". Its purpose is to solve the more serious software crisis problem faced by CloudComputing software system.

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, using 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.

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.
