The primary advantage of using virtualization technology for corporate applications is to achieve better utilization of resources, such as hardware, software, network and storage. Virtualization technology allows multiple applications to run on a single physical server or device, which reduces the need for additional hardware and maintenance costs. Virtualization technology also enables dynamic allocation and reallocation of resources according to the demand and priority of the applications, which improves efficiency and flexibility. The other options are not the primary advantage of using virtualization technology, although they may be some of the benefits or challenges depending on the implementation and configuration.
