IaaS is the capability where a consumer can deploy and run arbitrary software, and applications including OS on a cloud provider hosted and managed Infrastructure (Servers, Storage, Virtualization, Networking) SaaS is the capability where a consumer can use the cloud provider’s applications or services running on a cloud infrastructure. The consumer has no control on the Infrastructure or the application.

IaaS is when the hardware is hosted by a vendor, but the customer manages it, like Google Cloud Platform and AWS.

Correction on IaaS on


In SaaS, everything is hosted in the cloud, the applications, the databases, the servers, everything. In IaaS, the application servers are local, and maybe even the databases, but there's data in the cloud hosted by a vendor, maybe analytics, maybe some services, inventory, etc.
