To create environments for testing, development, or demonstration, several identical virtual machines are required. Use a technology as VMware vSphere or Microsoft Hyper-V, for implementing a dedicated virtualized infrastructure and use templates, would be the best choice.<\/p>\n

This solution offers both advanced administration and security capabilities, and allows a centralized access for users. However such an infrastructure needs dedicated servers and networks and could represent high costs. Furthermore it is not always usable from outside the company.<\/p>\n
