I am a college student with a predominantly business background looking into a business concept, which centers around remote access of Linux applications. I have experience with Citrix XenApp through work and I've trying to find a similar system for the Linux platform without much luck. Open source is preferable, as I will need to create a custom client and I would prefer to dedicate my budget entirely into coding and infrastructure setup.
My question is: Are there any Linux Server to Linux Client XenApp equivalents available?
