I currently have my old PC sitting in my closet being a headless server (running Ubuntu Server). I use it as a file server, web server, and backup server. (The hostname is mneme, the Greek muse of memory.) Are there any major reasons for me to consider replacing this non-virtualized setup with a personal cloud running on the same or similar hardware?
The major reason I can think of would be separation of services. For example, my backup system and my apache web server have nothing to do with each other directly, so they could run in separate instances. If I want to experiment with some new service (e.g. set up a personal mail server), I could do it in a brand new instance and then later, after the inevitable miserable failure, I can just blow the whole mess away without affecting my other services. Is this something that I could do with one or two computers running a personal cloud? Are there other advantages to setting up a personal cloud?
