From bird view point, all features looks the same from various cloud storage providers, including IAM security policies. But there is a huge difference with respect to minimum retention period, egress costs, in some cases ingress costs. Just to reduce the complexity in the architecture or design, most of the storage consulting competitors or the customers would take the short cut in forcing themselves to a single vendor. This increases the total cost ownership.
