What I see often is that it's hard and costly to replicate the whole cloud experience in-house. OpenStack is a behemoth to operate. However, if you build something more specific to your needs (and often mix in selected public cloud services), you'll get a much cheaper stack.
Small businesses can often run very efficiently with a few rented physical servers in a colo, G Suite and AWS S3.
Larger ones can provide a platform specific to the technologies used in-house and combine with public cloud for any other tech stacks.
