This article mainly introduces "what does cloud computing refer to". In daily operation, I believe that many people have doubts about what cloud computing refers to. The editor consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer the question of "what does cloud computing mean?" Next, please follow the editor to study!

Do you know what cloud computing is? In fact, there is no definite definition at present. However, in a nutshell, cloud computing refers to the unified deployment of your software and services in the data center, unified management, so as to achieve high scalability.

Cloud computing has the following characteristics:

Virtualization and Automation

Servers, storage media, networks and other resources can be replaced at any time

All resources are managed uniformly in the cloud

Highly scalable to meet business needs

Focus on delivering services to the business

I. deployment of cloud computing

In terms of deployment, there are two types of cloud computing:

Private cloud: the data center is deployed within the enterprise and managed by the enterprise itself. Microsoft provides Dynamic Data Center Toolkit to facilitate the management of your own data center.

Public cloud: data centers are provided by third-party cloud computing vendors who help enterprises manage infrastructure (such as hardware, networks, etc.). The enterprise distributes its software and services in the data center provided by the supplier and pays a certain rent. Windows Azure is such a public cloud platform.

Second, the operation mode of cloud computing

In terms of operation, there are three types of cloud computing:

Software as a Service (SaaS): cloud computing operators directly provide software in the form of services for end users to use. Some services also provide SDK, which allows third-party developers to carry out secondary development. In this mode of operation, developers usually can only develop plug-ins for existing products, but cannot fully tap the characteristics of the platform and operating system, but they can add new features to existing products without having to implement them from scratch. Products such as Microsoft's Bing,Windows Live,Microsoft Business Productivity Online fall into this category.

Platform as a Service (PaaS): cloud computing operators provide their own development and deployment platform to third-party developers. Third-party developers develop their own software and services on this platform for their own or other users' use. In this mode of operation, developers have more freedom to exert the powerful functions of the platform without being bound by existing products. Windows Azure is just such a product.

Infrastructure as a Service (IaaS): cloud computing operators provide but do not manage the infrastructure. Third-party developers hand over the developed software and services to their own company's IT administrators, who are responsible for deployment and management. In this mode of operation, developers and IT administrators have maximum freedom, but because they have to manage part of the infrastructure on their own, it is usually costly and demanding for administrators. Microsoft has not yet provided IaaS's cloud computing operation model, but we are considering how to give developers and IT administrators more freedom.

III. Summary

Cloud computing refers to the unified deployment of your software and services in the data center, unified management, so as to achieve high scalability.

In terms of deployment, cloud computing can be divided into private cloud and public cloud.

In terms of operation, cloud computing can be divided into three categories: SaaS,PaaS,IaaS.

At this point, the study of "what does cloud computing mean" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
