Virtual v’s Physical Appliances – 4 Compelling Reasons for Change
Scalability and Mobility - part III
The ability to be able to lift an application from one virtual machine and deploy it on another provides a powerful framework for rolling out services across the organization. As the head count grows, new virtual machines can be instantiated and the number of virtual machines driving a specific application can be increased to meet the demand. Likewise, reduced demand for certain applications can be addressed by removing the image from one or more virtual machines, freeing up these resources for other applications. From a geographic perspective, new applications can be deployed at remote sites simply by copying the virtual image to the server or servers at the remote site.
When a specific server needs to be taken offline for whatever reason, the virtual images executing on that server can be migrated to a new virtual machine without issues of platform version or operating system version.
