Now we all know that cloud computing is really hot in society, but it is also very vague. Some people buy cloud TV, but they don't need it after buying it. Cloud can be seen everywhere. So, what is the concept of cloud and what stage is cloud computing in? What is our understanding of cloud computing at this stage? Today, Micronet will come to have an in-depth communication with you.
First of all, Micronet believes that cloud computing is really important. It is a very important technology in today's era and will have a profound impact on cloud computing in the future. However, the current business concept of cloud computing, such as cloud TV and cloud mobile phone, has made the cloud very popular. In this case, it is difficult for users to know what is cloud and what is not. This is a business concept.
The second is the form of service. We all know that there are three types: IAAS, PAAS and SAAS. The three existing services actually fully reflect the IT resource services.
In addition, cloud computing is also an actual implementation technology. We know that there are many IT resources. For example, we now have storage resources, computing resources, computers, software, and platforms. Then there are three forms of IT resources: centralized, decentralized, and distributed. In the IT data center, our IT resources exist in a decentralized way, that is, there is no connection between devices. So the cloud is actually a distributed system that connects distributed devices together through the network.
So there are some basic definitions of cloud here. We have sinicized the American definition. First of all, what is cloud? Like clouds in the sky, it is composed of many small sources, which is equivalent to that clouds are composed of objects. So clouds are indeed composed of units. So we call them cloud units. There is also the word cloud unit abroad. In this regard, we refer to the basic concept that constitutes the cloud as the cloud unit. Both units require high-speed network connections. Thirdly, these cloud units are organized and managed through algorithms to form a shared and configurable resource library. The fourth is to use virtualization technology for segmentation and provide it to users according to their needs.
Cloud has five characteristics. The definition of cloud is as follows. Cloud has five basic characteristics. The first one is composed of cloud elements. People come from different industries and different aspects. Some may be manufactured. You can know that there are many things that can be done inside cloud units at present. Secondly, cloud units need to be connected through broadband networks, so broadband networks are the foundation of the cloud. The third feature of cloud is distributed system, the fourth feature is the use of virtualization technology, and the fifth feature is to ensure security. Cloud computing has five characteristics.
What types of services does cloud computing provide? The first is IAAS, which is a service mode. For example, virtual machines, storage, and computing power are IT resources, which are IAAS. However, Jiang Lintao said that he was not very in favor of infrastructure construction.
The other method is PAAS, the running software platform, which is a platform. But now I notice that this platform is not directly oriented to users, but to developers. As we all know, Google Maps has played a lot of roles in our use process. When you use Google Maps, it will not use PAAS, but will use IAAS. When I am a developer, I will use it, and users will use my content. At this time, Google Maps is a platform. Therefore, the concept of platform is still very practical at this time, especially after the development of the Internet and the massive opening of APR.
The running software is not just SAAS. Cloud computing is first to realize business. The physical entity of cloud computing is the data center, and cloud computing can realize a full range of services.
Three conclusions are put forward for the research of cloud computing. The most basic conclusion, what is cloud? First of all, cloud is not commercial hype, cloud is not a form of service, cloud is a way of technology implementation, cloud is to organize resources through a unified network, these resources are IT resources, IT resources include computing resources, storage resources, software, platforms, so it is a distributed implementation technology, virtualization allocation technology for users.
Secondly, the physical entity of the cloud is the data center. Now there are clouds everywhere, so we can see that the entity of the cloud is the data center. We know that the original data center is actually decentralized. I have many rooms, and there are many devices in the rooms. The devices are connected through the network, but there is no connection between the devices. But the cloud connects all the devices. The data center is the physical entity of the cloud. Of course, the data center is not necessarily completely cloud. So there are cloud based data centers and non cloud based data centers. The cloud free data center devices are not connected, and the cloud data center devices are connected. The cloud data center has a cloud technology unit and a data center network, and what can really see the cloud is on the data center.
Finally, let's draw a conclusion that cloud can provide a full range of IT resource services. Therefore, I focus on IT resources rather than communication resources. What are IT resources, computing resources, storage resources, virtual machines, and usually actual physical IT resources. Another IT problem is that we know that the concept of platform is vague. All three together, are IT resources compressed? In this way, the cloud does provide a comprehensive IT resource service for the future. It turns all IT resources into a resource pool for users. This is the understanding of the micro network for the cloud computing industry, and I hope it can help you,.
