What is IaaS, PaaS and SaaS?

Not so long ago, all of a company’s IT systems were on-premise, and clouds were just white fluffy things in the sky. They still had confusing acronyms for things but not quite so many. Let's break down what these different terms mean.


  • 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.
