Network topology can be King in these decisions
You missed some critical decision points.
- Where are your users in relationship to the VDI or TS servers?
- What are your bandwidth constraints?
- Does the user need off-line access?
- Actual costs vs potential soft cost savings. Few of us get to claim soft cost savings in a cost study. The finance guys are all about actual costs.
Physical, AppV, MedV, checked out VDI, VDI hosted on server and TS all have their strengths. Cost for infrastructure to support virtualization, the cost of a team to support virtualization, the cost of virtualization software, the licensing cost of the virtualized OS, the cost of patching tools, the cost of security tools, the cost of tools to manage the virtualization solution and the licensing of applications to run virtualized all add up.
You most definitely need to do your homework and build a good business case for the various virtualization solutions. Those up front and continuing physical costs can be eye opening. Don't rely on virtualization to be the be all end all savior for your problems.
All that said, there are areas where these virtual solutions are lifesavers.
