One of the hallmarks of virtualized servers is that they are able to handle large amounts of data. Many companies can easily migrate all of their OS and application data to a single virtual server and still have room to spare. At the most basic level, a virtual server can support multiple levels of operating system platforms, each partitioned into their own separate space. From there, each platform can be run independently and as if no other platform on the server existed, giving information and data stored on the server a level of protection should the data from another OS become corrupted or unusable.
Virtual servers can do much more than simply provide a sensible storage solution, however, as they also offer the ability to virtualize application data as well as that of operating systems. This application virtualization allows for far greater mobility and agility on the part of a company but does limit them to a smaller number of virtualized OS systems.
No matter the choice made or the hybrid defined, a company can see significant adaptive gains moving to a virtualized environment, giving them the ability to create the kind of operating, access and retrieval systems that best suit their needs. Consider a company that predominantly runs Windows but needs to deal with a client whose focus is Linux; with a virtual server setup, the company can run instances of both a Windows and Linux server with no issues, broadening their ability to do business across the board.
Properly virtualized servers with tight security and attentive management can provide companies the ability to experiment with their OS and application needs and give them the ability to be flexible and mobile when needed.
