The core technology in cloud computing is virtualization, which can be said to be an important feature that distinguishes cloud computing from traditional computing modes. Virtualization can transfer the entire execution environment of the application to other nodes in the cloud computing platform in the form of packaging, which realizes the isolation of the execution environment of the application from the physical environment and makes the environmental change of the application easy to realize.

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

Importance of application virtualization:

SaaS and cloud computing are hot topics in IT field in recent years, and there is an important relationship between them. SaaS is the application performance of cloud computing, and cloud computing is the basic service guarantee of SaaS backend. SaaS is an application mode that takes the Internet as the carrier and the browser as the interactive mode, and transmits the program software of the server to remote users to provide software services.

In other words, today's SaaS, everyone is basically talking about browser-based applications, and it is precisely because of this limitation that many SaaS can not provide richer application services, and the implementation process of SaaS applications in this mode is too slow. Based on the above shortcomings, application virtualization came into being, which solved the confusion of informatization and will surely lay an epoch-making significance for the promotion of informatization construction.
