We're investigating different options we have to provide remote access to 1 app on our windows server. In terms of pricing, purchasing CALs is quite cheaper than installing Citrix XenApp.
Would enabling concurrent RDP sessions be enough for up to 20 users accessing the same application concurrently? Our server is well dimensionned and in theory (just doing the linear mathematical calculations) can handle it.
What kind of caveat am I omitting? Our scenario is very basic (1 java based app) but I'd like to make sure.
