But none of these servers would give you control over computing you do on it, unless it's your server. It may be OK to trust your friend's server for some jobs, just as you might let your friend maintain the software on your own computer. Outside of that, all these servers would be SaaSS for you. SaaSS always subjects you to the power of the server operator, and the only remedy is, Don't use SaaSS! Don't use someone else's server to do your own computing on data provided by you.
