As terminal virtualization and Application Virtualization grow, IT managers must recognize that server requirements can change dramatically because of the different virtualization technologies that are selected for application delivery. Traditional non-virtualized applications are delivered, applications need to be installed on a physical server, and end users access applications over the LAN. 　　Because this delivery model consumes only 5% to 10% of the server's computing resources, few people pay attention to the overall configuration of the server. As long as the server can meet the needs of computing resources required by the application, administrators are less concerned about the resource consumption of the application delivery ...
