Adding contents related to personal/lab server

[Ruiqi-CUB]

Plenty of labs are still using personal/lab/departmental servers as their primary computing resources. It would be helpful to add the option here and to compare it with cloud computing.

Hi @Ruiqi-CUB, I think this is a good idea, especially for giving the instructions for accessing it, the different options available and maybe also including an optional section on VPN usage. The risk is that this would be a very long section for comprehensively including the options and tools and would deviate from the episode.
