Regarding the longevity of storage media many of the products that we use today, hard disk drives, flash memory, optical discs and magnetic tape will react with the ambient environment and gradually lose the data stored on them or disintegrate over time.
Techniques such as extracting operating parameters, comparing application profiles across VMs (to look for signs that one has been successfully attacked), and analyzing application behavior in memory (as opposed to just code stored on disk) are far easier in a virtual environment and provide a huge advantage for stopping the most sophisticated threats.
Airtel Vodafone now has an ideal environment to suit all its needs, enabling rapid low-cost integration of data stored in various operational surroundings.
