Application virtualization requires a full virtualization layer. It replaces runtime requirement part provided by operating system while implementing application virtualization layer. This implementation is possible with the help of sequencing the application procedure. Application virtualization is implemented in such a manner that it uses virtual resources for its execution. Application virtualization is mainly used to access the same version of the application at the same time on multiple machines. Application virtualization has some other benefits like security enhancement, easy migrations of operating systems, reduction in administration costs. Application virtualization is efficient in case of administrative control over machines for installing, patch, upgrade operations from a single locat ion moreover flexibility, reduction in the risks associated with compatibility issues. Application virtualization can be used without combining it with desktop virtualization on laptop or computers. Application virtualization is utilized by enterprises for better implementation, speed, efficiency, and operational process improvement. Application virtualization is not installed, so there is no residue on the removal of application, no registry issues also delivered dynamically so applications can be accessed offline, online, or anywhere.
