Cost, uptime & ease of use are key words in the IT industry. Virtualization works exactly in a way by which it achieves all 3 goals. In all physical environments, we observed that most of the servers are under utilized or running with high load. So just investing more is not a solution. In a conventional setup, it take weeks to add a new server and needs a long wait for testing applications. In a virtual environment, it's just a matter of a few clicks without any additional investment. Resource optimization, consolidation, less administration with maximum security are all at the tip of the fingers.
