makes the call.
Next silly question?
Sure, the person who pays the bills makes the call but they usually make that call based on cost. If it costs less in hardware/support/security/reliability/etc.. to move to the cloud, then it's usually a safe bet to do it. In most organizations, the person paying the bill would ask the IT department for costs and make the decision based on that. In the company I work for, we only have a few servers and by moving to the cloud we have a fixed bill, a reduced workload, no need to replace hardware, more reliability, etc... Once we found a good provider, there was really no downside. On a side note, our first attempt to move to amazon was a disaster and we have been much happier with stormondemand. The cloud isn't a single entity and each provider has different offerings and what works for one company might not work for the next so the whole vague "move to the cloud" is almost as useless as saying you need to buy a server or a network. You need to spec it out the same way you would spec out an in-house server, network device, or ISP connection and weigh all the pros/cons.
