According to a prediction made by IDC back in 2010, 70 percent of servers would be virtual by 2014. Gartner now estimates Windows being at between 60 and 70 percent virtualized and Linux being at between 35 and 45 percent virtualized, making IDC’s largely accurate. In addition, very few systems shipped today are not virtual, borne out by the fact that there is a decline in the number of servers being shipped and the growing number of virtualized environments that exist today.
To sum this up, physical servers are becoming increasingly uncommon and virtual servers are now the most common mode adopted in all industries, across all sectors, regardless of company size. Despite virtualization being common today, there is still room for significant evolution and growth to occur.
