In short
The three main cloud service models are infrastructure as a service (IaaS), platform as a service (PaaS) and software as a service (SaaS). Each shifts more of the technology stack from the customer to the provider.
Key takeaways
- With infrastructure as a service, the customer manages operating systems, applications and data; the provider runs the hardware and network.
- With software as a service, the provider runs nearly everything, but the customer still manages its users, data and access settings.
- The customer always remains responsible for its own data and for monitoring the provider.
