Can anyone tell me when the era of cloud computing began? Why is it called cloud computing?

The problem of cloud computing is not a historical problem, is it?

Cloud computing is a computing method that the calculation of data is completed in the cloud, not at the end of the period you use, like our mobile phone, which belongs to the computing terminal. Its important thing is that it can change the way we live, and it is also the core technology of today's technology!

Just like mobile online shopping apps, it is Alibaba Cloud that provides cloud computing that allows us to have a better user experience. Just imagine, when we search for a keyword in a mobile online shopping app, a large number of search results will immediately appear, allowing us to choose products as we like, which is the result of the computer calculating a large amount of data. If these data are calculated on the terminal, our mobile phones cannot bear such a large amount of calculation, and even if the calculation is completed, it will take a lot of time, which will affect our experience of using the app.

However, these data can be quickly completed under the calculation of a large computer in the cloud, and then the results of the calculation can be transmitted to the terminal through the network, so that our mobile phone is just a device for sending and receiving.

With cloud computing, our terminal is just a transceiver device, a large amount of data is done in the cloud, and our terminal only processes a small amount of data.

In the future, our computers may only need a very simple configuration to complete a large amount of data processing. Maybe we only need a device the size of a USB flash drive to beat today's high-end computers. In terms of gaming, in the future, we will only need simple configurations, and we will not need expensive graphics cards to play large 3D games, because a large amount of data computing is done in the cloud.

We can simply understand cloud computing as a mode of computing:

IT resources, data, and applications are provided to users over the network as services. In this model, the end user does not need to know the details of the infrastructure in the cloud, nor does it need to have the corresponding expertise, but only need to focus on what resources are needed and how to get the corresponding services through the network. Think of the cloud servers, cloud databases, and load balancers provided by Little Bird Cloud, which are all cloud products that should be produced by using cloud computing technology slowly.

Cloud computing services provide businesses with flexibility in their work. As we enter a new era of technology, cloud computing will play an important role. With cloud computing, people can save themselves the expense of purchasing hardware and software and setting up an on-site data center.

Cloud computing is a noisy new and useful tool for upgrading, and it will play an increasingly important role in the technology world.

Cloud computing is to connect all the large and small volumes of servers into one, after the overall calculation, and then divided into multiple small programs to distribute to users, because cloud computing is particularly fast, the ability to deal with rotten states is particularly strong, covering life, work, etc., so he is very important to us.

Cloud computing is a kind of network computing, cloud computing is currently widely used in computer technology, we basically come into contact with cloud computing every day, such as we use mobile phones to surf the Internet, shopping, online payment transactions, etc., these are achieved through cloud computing, the application scope of cloud computing is expanding day by day, and its potential is immeasurable.

In fact, the cloud represents the Internet (Internet), through the computing power of the network, instead of using the software you originally installed on your own computer, or replacing the original action of storing the data on your own hard disk, you turn to the network to carry out various work, and store the archives on the network, that is, the huge virtual space. We use the web services we use, store the data in a server on the network, browse the web pages of these services through the browser, and use the above interface to perform various calculations and work.

Cloud computing will be the next big thing in networking.

Cloud computing technology is a computing mode that provides dynamically scalable virtualized resources through the network as a service.

The face of the explanation zhi release dao is clear enough to answer.

Definition: Cloud computing is an emerging business computing model. It distributes computing tasks across a pool of resources composed of a large number of computers, enabling various application systems to obtain computing power, storage space, and various software services as needed.

Description: This pool of resources is called a cloud. A "cloud" is a set of virtual computing resources that can be self-maintained and managed, usually a cluster of large servers, including computing servers, storage servers, broadband resources, and so on.

Cloud computing centralizes all computing resources and is automatically managed by software without human involvement. This allows application providers to focus more on their business without worrying about tedious details, which is conducive to innovation and cost reduction.

Some people have made an analogy: it is like moving from the old single generator model to the centralized power supply model of the power plant. It means that computing power can also be circulated as a commodity, just like gas, water and electricity, which is easy to access and inexpensive.

The biggest difference is that it is transmitted over the internet.

Cloud computing is the development of parallel computing, distributed computing, and grid computing, or the commercial implementation of these computer science concepts. Cloud computing is the result of a hybrid evolution of concepts such as virtualization, utility computing, IaaS, PaaS, and SaaS.

As early as 2002, Liu Peng proposed the concept of computing pool in view of the impracticality of traditional grid computing ideas: "It connects high-performance computers scattered in various places with high-speed networks, organically glues them together with specially designed middleware software, accepts computing requests from scientists around the world with a web interface, and assigns them to suitable nodes for operation." Compute pooling can greatly improve the service quality and utilization of resources, while avoiding the inefficiency and complexity caused by dividing applications across nodes, and can meet the practical requirements under the current conditions.

If the "high-performance computers" in the article are replaced with "server clusters", and the "scientists" are replaced by "business users", it is very close to the current cloud computing.

In 1983, Sun Microsystems proposed "the network is the computer", and in March 2006, Amazon launched the elastic compute cloud; EC2).

Cloud computing is the distribution of computing across a large number of distributed computers, rather than local computers or remote servers, and enterprise data centers will run more slowly than the Internet. This enables enterprises to switch resources to the applications they need, accessing computers and storage systems on demand.

Cloud computing is the model for the addition, use, and delivery of Internet-based services, typically involving the provision of dynamically scalable and often virtualized resources over the Internet.

Cloud computing has several main characteristics:

Dynamic resource allocation. Dynamically divide or release different physical and virtual resources according to consumer needs, and when a demand is added, it can be matched by increasing the available resources to achieve rapid and elastic provision of resources.

Self-service of demand services. Cloud computing provides customers with self-service resource services, and users can automatically obtain self-service computing resource capabilities without interacting with the provider. At the same time, the cloud system provides customers with a certain application service catalog, and customers can choose the service items and content that meet their own needs in a self-service way.

Network-centric. The components and overall architecture of cloud computing are connected by a network and exist in the network, while providing services to users through the network. With the help of different terminal devices, customers can access the network through standard applications, so that cloud computing services are ubiquitous.

Services are measurable. In the process of providing cloud services, according to the different service types of customers, the resource allocation is automatically controlled and optimized through metering. That is, the use of resources can be monitored and controlled, and it is a pay-as-you-go service model.

Pooling and transparency of resources.

What is cloud computing may be a question for many friends.

The Internet promotes the continuous development of society, and the Internet industry has brought great changes to everyone's life since it entered the public eye.

The main role of cloud computing is to provide massive data computing power, public cloud, private cloud and public-private hybrid cloud and other cloud computing related technologies have been applied in real time into production and life, as an emerging hot industry, the talent gap of cloud computing positions is very large, and many well-known enterprises have been studying cloud computing technology that can bring better development prospects for the company.

Cloud computing can increase the utilization rate of each server, so as to achieve open source and reduce expenditure.

Uses of Cloud Computing:1. Cloud servers are required for building ** applications;

2. Internet + medical care, Internet + tourism, etc., with the help of it, it can open source and reduce expenditure;

3. The Internet of Everything is inseparable from it;

4. Big data can help enterprises grow better.

To learn IT technology, you must lay a good foundation and learn systematically under the guidance and planning of professional teachers.

Network foundation and Linux system management

Optimization technology of the system

The establishment of virtualization and cloud platform can actually contact enterprise projects to realize capability monetization.

Also known as instances, public clouds are also known as ECS, cloud hosts, cloud servers, etc.; VPC: Virtual Private Cloud, a logical isolated area allocated in a cloud resource pool, in which customers can launch resources in their own defined virtual network, and can fully control the virtual networking environment, including choosing their own.

IP address ranges, creating subnets, configuring routing tables and gateways, etc. (VPC concepts vary slightly from vendor to vendor); Virtualization: Virtualizes physical resources into logical resources that are provided on demand.
