虚拟化与云计算的区别和联系(云计算和虚拟化功能的区别是什么)

The computing media of the two are different:

Cloud computing uses computers Connect to the data center through , laptops, mobile phones, etc., and perform calculations according to your own needs. For example, Xiaoniao Cloud can elastically expand resources.

Transparent computing selects and uses corresponding services (such as computing, telephone, television, Internet and entertainment, etc.) calculation model.

Introducing the concepts of the following two:

Cloud computing (cloud computing) is the addition, use and delivery model of Internet-based related services, usually involving the provision of dynamic, easily scalable and Often virtualized resources. Users access the data center through computers, laptops, mobile phones, etc., and perform calculations according to their own needs.

Transparent computing is a method in which users do not need to be aware of the specific location of computer operating systems, middleware, applications and communication networks; they only need to use various terminal devices (including Computing mode that selects and uses corresponding services (such as computing, telephone, television, Internet and entertainment, etc.) among various terminal devices (fixed, mobile, and in the home).

The core technology in cloud computing is virtualization. It can be said that virtualization is an important feature that distinguishes cloud computing from traditional computing models. Using virtualization, the entire execution environment of an application can be transferred to other nodes in the cloud computing platform in a packaged form, thereby isolating the execution environment of the program from the physical environment and making it easy to change the environment of the application.

It is precisely because of the maturity and widespread application of virtualization technology that computing, storage, applications and services in cloud computing have all become resources. These resources can be dynamically expanded and configured, and cloud computing can finally be used in Logically presented as a single whole.

Extended information:

The importance of application virtualization:

SaaS and cloud computing have been discussed in the IT community in recent years. Hotspots, there is an important relationship between them. SaaS is the application performance of cloud computing, and cloud computing is the back-end basic service guarantee of SaaS. SaaS is an application model that uses the Internet as a carrier and a browser as an interactive method to transfer server-side program software to remote users to provide software services.

In other words, today’s SaaS, everyone basically talks about browser-based applications, and it is precisely because of the limitations of this method that many SaaS cannot provide richer application services. Moreover, the implementation process of SaaS applications under this mode is too slow. Based on the above shortcomings, application virtualization emerged. The emergence of application virtualization solves the confusion of informationization and will surely lay an epoch-making foundation for the advancement of informationization construction. significance.
