As my stock of VPSs gradually increases, I find an ever persistent need to find some way to join them together. I have tried Webmin, but that only seems to scratch the surface of what I really need. Is there a way to combine VPSs to make them into a virtual 'cloud' where they act as one, utilise the space on the HDD and the available RAM together. If that is not possible, I was looking for ways to create a backup server for my computer, where I could combine multiple VPS's data together so that it is backed up in as many places as possible. For instance, if I had 3 servers, and uploaded a folder to the master, both slaves would keep a direct copy of this folder.
If none of this is really possible, is there some sort of centralised control software that will allow me to manage, monitor and utilize all my VPSs in one place?
