Shared responsibility + IaaS/PaaS/SaaS
Shared responsibility + IaaS/PaaS/SaaS. Responsibility is shared, and the split changes by service model. SaaS (Software as a Service): customer manages least (config/users/data governance). PaaS (Platform as a Service): provider manages more platform. IaaS (Infrastructure as a Service): customer manages more. Key concept: Shared responsibility: provider vs customer.
