Service models for public cloud
Most of the services you can use with public cloud are delivered as either infrastructure, platform or software — IaaS, PaaS, SaaS.
-
Security ownership in all service models
Government organisations always own the risks of their information in a service model — assess the risks before using one and set up proper security configurations.
-
Shared responsibilities for security in each service model
Government organisations and service providers have different responsibilities for each service model.
-
Software as a Service
Access providers’ applications over the internet using Software as a Service (SaaS).
-
Platform as a Service
Over the internet, access providers’ operating systems and applications using Platform as a Service (PaaS).
-
Infrastructure as a Service
Run operating systems and applications by accessing, over the internet, providers’ computing resources using Infrastructure as a Service (IaaS).
-
Other types of service models for public cloud
Most public cloud services combine aspects of multiple service models. Other types of service models have been developed to handle different needs — such as DaaS, BPaaS, CaaS and FaaS.
