I used to sell both cloud products and server/storage infrastructure. There are too many factors, often legal requirements and the umbrella company policies not being flexible, but , if you need 20 or more servers and redundancy and are legally permitted to go cloud, do it. You can run non business critical parts of the it on cloud and see if it makes sense to the cfo. Buying physical servers and the premises is one thing, but there's so much more to it, it's far from plug and play. You need hypervisor, licences, one or two admins, it adds up.
