The other nice thing about primarily cloud infrastructures is, as an infra/ops guy I can build tooling and abstractions over it to allow developer and BI teams to go much faster without my help at all. An on-prem solution can allow this, but the fact that so much of the complexity is managed by the cloud provider makes it a lot faster and easier. A feature that could take months to roll out is usually offered by AWS for a price tag that's easy for the business to understand.

My one irritation with stuff like AWS is that a lot of it is needlessly esoteric, to the point where I think they make their docs bad on purpose to get you to buy their enterprise support packages.
