Why virtualization is important?

 Data centers are at capacity  Servers are under utilized  Legacy hardware and systems  Application compatibility issues

 Server consolidation  Service or application isolation  Simplified server deployment  Increased service and application availability  Multiple operating systems can run on one consistent platform

 Some software solutions are not supported in virtual environment  Some software solutions require special license in virtual environment  Some software solutions comes with special virtualization use rights
