I think all of those services are cloud-based, yeah?
Cloud services are a great option to have available, but there are many reasons organizations choose to manage their own instances... pre-existing infrastructure investment, flexibility, data location and control, cost structure, regulatory requirements, etc.
I read here that Mongo has started a cloud-based offering, but the core of their business competes against other self-managed storage software like MySQL, Postgres, Hadoop, etc.
