PLM in a Box
The client was unable to organize and support individual PLM instances at the corporate level. Wipro‘s solution, PLM in a Box, a solution architecture which hosts multiple PLM instances of in one box, enabled different divisions across the organization to access PLM applications through OSvirtualization.
