Virtualization has injected unprecedented energy into Hadoop, from the point of view of IT production management as follows: • Hadoop and other applications consuming different types of resources together deploy shared data centers to increase overall resource utilization; • Flexible virtual machines Operations allow users to dynamically create and extend their own Hadoop clusters based on data center resources, as well as shrink the current cluster and free resources to support other applications if needed.

Virtualization has injected unprecedented energy into Hadoop, from the perspective of it production management, as follows: · Deploying shared data centers with Hadoop and other applications that consume different types of resources increases overall resource utilization; • Flexible virtual machine operations enable users to dynamically create, expand their own Hadoop clusters based on datacenter resources, or reduce current clusters and release resources to support other applications if needed; With the HA, FT integration provided with the virtualization architecture, avoid ...

Cloud computing is the continuous development of user needs of the service model of natural generation, but also the beneficial support of green it.
