Ok, you built a private cloud in 15 minutes, great, but who paid for the kit you built your cloud on? and who installed it? someone somewhere has got to make the investment before you build virtual instances and set up a network, over time they must win as you win (savings wise) all you do is abdicate (and I use the word wisely) your entire IT out to billy bigcloud who has taken the risk that there are people out there who will pay for the service. tell me what happens in 5 years time when the virtual datacentre you've built starts to fail and become more problematic to maintain and billy bigcloud needs to upgrade all the servers.
In other words hes still got to pay for equipment, he has to maintain an environment, he has to pay the energy bill, so either your costs will start to creep up or he'll go bust as he is not getting the return on the investment he's made.
I suspect that you tell me about virtualisation and how each new server can now host 8-12 instances and thats where the savings are, as each server is paid for by cloud punters 10 times over, errr lets do the math, say $10 per month, $100 per month for 10 virtual servers on one host, total yearly income for cloud supplier £1200, total over 5 years income = $6,000 v cost of server £1200, plus energy, plus NOC, plus maintenance, plus say another DR server to give you 5 9'S for your environment, plus staff, divide NOC and patching/maintenance staff as they are spread out over the entire facility and I reckon it very close to break even. Add a contractual dispute or two for unplanned outages and the cloud supplier is on very shaky ground. You did write cast iron sla's and compensation payments into your tender document for your virtual data centre didn't you and i've not even got on to security !!
