What is SaaS, IaaS, and PaaS?

305 views

I was in a meeting and they’re talking about these. I looked it up on the internet but I just can’t wrap my head around it. It feels like a buzzword to me that you say during interview but I want to understand it.

SAAS: Software as a service. Instead of buying a piece of software and you’re done, you pay monthly to use the software like any other ongoing service.

IAAS: Same thing for Infrastructure. Instead of building your own server farm, you use someone else’s as an ongoing service.

PAAS: Same thing for Platform. Instead of having someone engineer a software platform for your needs, you use one that someone else is hosting for you, as an ongoing service.
