I'd bet Dropbox has way more raw bytes to store than FedEx. Plus, the Dropbox business model is based on data egress to clients, which is really expensive on cloud servers. FedEx needs data centers more for internal logistics, which is probably why they're going with Oracle.

Ask yourself what probably happened a few years later when they had to negotiate new leases from their datacenter landlords. Funny how they never put out a follow up press release about the enduring value of on-prem. Also a company that basically can’t grow and hardly turns a profit.

Really, not the first example I’d reach for.
