Virtualization – An Environmental Asset!

Virtualization

In this age of rapid upgradation and the need for progression, electronic devices are easily prone to get outdated. This results in sums of e-waste. World’s e-waste is anticipated to grow 33% by 2017 according to global reports. Accumulation of e-waste prompts resource shortage and environmental contamination, making it a disquiet to give a thought upon and take opted steps towards ‘Virtualization’ to make greener tomorrow!

Virtualization can be the simplest and cost efficient step taken to reduce e-waste. It comes hand in hand with the aid of a reduction in CAPEX (Capital Expenditure) & OPEX (operational Expenditure) resulting in ‘TOTAL PROFIT’. Virtualization as the concept specifies an act of creating something (such as Computer Hardware, OS, Storage, etc.) virtually, to facilitate one with the similar comfort of operations as provided in the physical environment, but of course with aid of advantages.

Virtualization has three levels:

Hardware level virtualization: In this hardware is virtualized similar to the physical machine. It is also called as system-level virtualization in which Physical machine is called as host and the virtual machine is called as Guest. It has three types of virtualization:

(1) Full Virtualization:

Hardware is completely simulated with the software called as hypervisor which directly interacts with the hardware to allow virtual machine reflect every aspect of physical machine. Every individual virtual machine runs of different platform unaware of another virtual machine, one virtual machine may have Linux as OS and other may have Windows.

(2) Partial Virtualization:

Hardware is not completely simulated, only some part of target environment is simulated. Hence, a few modifications in guest instructions may be required to suit virtual environment. It is highly reliable in sharing computer resources between multiple users with different virtual environments.
