Virtualization technology becomes the driving force of cloud computing

Http://www.aliyun.com/zixun/aggregation/13883.html "> Virtualization technology can abstract the underlying architectures such as physical resources so that the differences and compatibility of devices are transparent to the upper layers, This allows the cloud to manage the disparate resources at the bottom. In addition, virtualization simplifies application authoring, allowing developers to focus only on business logic without having to consider the provisioning and scheduling of underlying resources. In virtualization, these applications and services reside on their respective virtual machines, effectively isolating, and the collapse of an application does not affect the normal operation of other applications and services. In addition, the use of virtualization technology can be readily available for resource scheduling, to achieve the allocation of resources, applications and services will not be due to lack of resources and performance degradation, and will not be idle for a long time caused by waste of resources. Finally, the ease of creation of virtual machines enables applications and services to have more virtual machines for fault tolerance and disaster recovery, increasing their reliability and availability.
　　　　
It can be seen that because of the mature and widespread use of virtualization technology, computing, storage, applications and services in cloud computing have become resources that could be dynamically extended and configured, and cloud computing will ultimately be realized in a single, holistic form. Virtualization technology is the most critical and core technology driving force in cloud computing.
