What is the underlying technology and core of cloud computing

What is the foundation of cloud computing?

Cloud computing is about high-level programming languages, database management techniques, and knowledge of system architecture. Cloud computing is a kind of distributed computing, refers to the network “cloud” will be a huge data processing program is broken down into countless small programs, and then, through the system composed of multiple servers to process and analyze these small programs to get the results and return to the user.

With the continuous expansion of the cloud computing market, the cloud computing application scenarios are now in constant enrichment, with cloud computing skills are also many companies are highly paid talents, many people want to switch to learning cloud computing, because they are zero basis do not know to learn the cloud computing need to have what foundation? Cloud computing is different from other IT positions zero basis can also be self-taught very well, cloud computing involves more knowledge.  

1. Learning the foundations of cloud computing

From the cloud itself, the core technologies of cloud computing, including programming models, massive data distribution and storage technology, massive data management technology, virtualization technology, as well as cloud computing platform management technology; from the perspective of recruiting, the majority of companies for the development of cloud computing talent job requirements: familiar with the mainstream languages such as Java / Python, etc., the need for a good knowledge of cloud computing. Python and other mainstream languages in at least one, master the common data structure algorithms, with the cloud computing field or operation and maintenance, operation and management platforms, mainstream cloud computing product architecture design experience, leading the product or platform version of the maintainability design. It can be seen, you want to learn cloud computing and meet the needs of enterprises from a zero base, you must master a programming language, master Linux operation and maintenance or Python operation and maintenance, familiar with the public cloud and private cloud platform applications.

2. Systematic study of cloud computing

The above is the introduction of the foundation for learning cloud computing, you can see that you want to learn cloud computing or need to have a certain foundation in the IT industry, otherwise it is still very difficult to learn.

What are the core technologies in cloud computing?

Cloud computing data center operating system is the key technology of large-scale system software, and is also the basic core technology of cloud computing. The essence of cloud computing is to aggregate the dispersed resources scheduling, in the form of services provided to the audience. Cloud data center operating system is the cloud computing background resources for fusion, intelligent scheduling, elasticity and scalability of large-scale system software, in the process of conversion of resources to services to play a core role in cloud computing, cloud computing “nervous system,” said the cloud computing is the core of basic software technology. I know this from IT Extra.

What are the key technologies included in cloud computing?

Virtualization and resource management technologies are the most important core technologies for cloud computing.

It provides infrastructure-level support for cloud computing services, and is the most important driver for ICT services to move rapidly towards cloud computing. Many people have misconceptions about cloud computing and virtualization, thinking that cloud computing is virtualization. But in fact, virtualization is only an important part of cloud computing, but can not represent all the cloud computing. The biggest benefit of virtualization is to enhance the elasticity and flexibility of the system, reduce costs, improve services, and increase the efficiency of resource utilization.

Distributed data storage technology, by storing data in different physical devices, can realize dynamic load balancing, automatic takeover of faulty nodes, with high reliability, high availability and high scalability. Because in a multi-node concurrent execution environment, the state of each node needs to be synchronized, and in the event of a single node failure, the system needs an effective mechanism to ensure that other nodes are not affected.

Resource management techniques. Cloud computing needs to process and analyze 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 system needs to have the ability to efficiently deploy a large number of server resources to make them work better together.

The core technology of cloud computing

1, virtualization technology

Virtualization is one of the most important core technologies of cloud computing, which provides infrastructure level support for cloud computing services, is the most important driving force for ICT services to rapidly move towards cloud computing. It can be said that without virtualization technology there is no cloud computing services landing and success.

2, distributed data storage technology

Another major advantage of cloud computing is the ability to quickly and efficiently deal with massive amounts of data. In today’s data explosion, this is critical. In order to ensure high reliability of data, cloud computing usually uses distributed storage technology to store data in different physical devices. 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.

3, programming model

In essence, cloud computing is a multi-user, multi-tasking, concurrent processing support system. Efficient, simple and fast is its core concept, which aims to conveniently distribute powerful server computing resources to end users through the network, while ensuring low cost and good user experience. The choice of programming model is crucial in this process.

4. Large-scale data management

Dealing with massive amounts of data is a major advantage of cloud computing. Then how to deal with it involves many levels, so efficient data processing technology is also one of the indispensable core technologies of cloud computing. For cloud computing, data management faces huge challenges. Cloud computing should not only ensure data storage and access, but also be able to carry out specific retrieval and analysis of massive data.

5. Distributed Resource Management

Cloud computing uses distributed storage technology to store data, so it is natural to introduce distributed resource management technology. In a multi-node concurrent execution environment, the state 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. A distributed resource management system is just such a technology, and it is the key to ensuring the state of the system.

6, information security

Survey data show that security has become one of the most important reasons to hinder the development of cloud computing. The data shows that ICT management in 32% of organizations already using cloud computing and 45% of organizations not yet using cloud computing cited cloud security as the biggest obstacle to further cloud deployment. Therefore, security is the number one issue that needs to be addressed to ensure that cloud computing can grow steadily and rapidly over the long term.

7. Cloud computing platform management

Cloud computing resources are huge in scale, with a large number of servers and distributed in different locations, running hundreds of applications at the same time, how to effectively manage these servers to ensure that the whole system provides uninterrupted service is a huge challenge. The platform management technology of cloud computing system needs to have the ability to efficiently deploy a large number of server resources to make them work better together.

8, green energy-saving technology

Energy saving and environmental protection is the global theme of the entire era. Cloud computing is also known for its low cost and high efficiency. Cloud computing has huge economies of scale and saves a lot of energy while improving the efficiency of resource utilization. Green energy-saving technology has become an essential technology for cloud computing, and more and more energy-saving technologies will be introduced into cloud computing in the future.
