cloud delivery models

A cloud delivery model represents a specific combination of IT resources offered by a cloud provider.

Three common delivery models are used:

  • Infrastructure-as-a-Service (IaaS) - The IaaS delivery model provides a self-contained IT environment comprised of infrastructure-centric IT resources.
  • Platform-as-a-Service (PaaS) - The PaaS delivery model provides a pre-defined cloud environment with already deployed and configured IT resources suitable for the development and deployment of applications.
  • Software-as-a-Service (SaaS) - The SaaS delivery model generally represents a product that exists as a shared cloud service offered by a cloud provider to cloud consumers.

Variations of these models can also exist.
