I read this wonderful piece as a lay person; I beg your pardon for the ignorance that I'm sure shines from my question.
This sounds to me like needing Infrastructure As A Service (or Platform As A Service). Am I right to say it's the sort of thing for which SlapOS could be used?
I only ask because I've been trying to understand available open-source ERPs recently and am in the (long, for me) process of trying to grok slapOS, and it sounds - again, to my mean understanding - like it could be the sort of thing that contributes to a European solution.
