Question: what is the difference between software as a service (saas) and platform as a service (paas)?
Answer: IaaS: cloud-based services, pay-as-you-go for services such as storage, networking, and virtualization. PaaS: hardware and software tools available over the internet. SaaS: software that's available via a third-party over the internet. On-premise: software that's installed in the same building as your business.
