David Marshall, writing for VMware has published a brief article on The Five Virtues of Virtualization, that explains how the technology can make a physical resource appear as multiple logical resources and, similarly, also make multiple physical resources appear as a single logical resource. Technically, with the use of virtualization software, the computer system gets transformed into a "virtual machine", running its own operating systems and applications. Interestingly, the virtual machine functions like a real computer but without any hardware components.

Marshall lists the five most significant advantages that can help enterprises enhance their overall performance:

Server unification and infrastructure maximization

Virtualization enables server unification that integrates various servers spread across an enterprise, enabling these servers to work by sharing applications and databases along with other infrastructure and resources, which leads to the maximizing of infrastructure and efficient resource usage for enterprises.

Reduction in cost of infrastructure

Virtualization enables administrators to reduce the number of servers, hardware devices and data centers, which not only downsizes the infrastructure and maintenance costs but also reduces power consumption.

Enhances flexible functionality of management

Virtualization requires fewer servers to perform the routine, repetitive, time consuming tasks such as configuration, upgrades, monitoring and system scheduling.

High accessibility of applications and data

Virtualization so transforms the applications and data in the virtual environment that high accessibility without any time delays and disruption results. This makes it possible to fulfill the needs of both customers and staff in a secure environment.

Improves system compliance

Even with customers using different OS and networks, virtualization makes it possible to form a virtual enhanced system unrestricted by different OS and network limitations, which makes it easy for users and clients to remain linked with the enterprise.

To learn more about virtualization in the enterprise, take a look at CIO.com's article Virtualization in the Enterprise Survey: Your Virtualized State in 2008 that reports on the results of a survey of nearly 300 CIOs who shared their experiences with virtualization. [...read more...]
