An IT infrastructure consultant is evaluating cloud service model boundaries for an enterprise retail organization. Match each cloud service model on the left to the client administration responsibility scope on the right.
- Infrastructure as a Service (IaaS)Installing guest operating systems, configuring network firewalls, and managing middleware; vendor manages physical host hardware and hypervisors.
- Platform as a Service (PaaS)Developing application code and managing database schemas; vendor manages runtime environment, operating system updates, and physical hardware.
- Software as a Service (SaaS)Configuring user access permissions and organizational data settings; vendor manages application software, operating systems, and underlying hardware.
Cevap
Infrastructure as a Service (IaaS) matches installing guest operating systems, configuring network firewalls, and managing middleware while the vendor manages physical host hardware and hypervisors. Platform as a Service (PaaS) matches developing application code and managing database schemas while the vendor manages runtime environments, operating system updates, and physical hardware. Software as a Service (SaaS) matches configuring user access permissions and organizational data settings while the vendor manages application software, operating systems, and underlying hardware.
In cloud computing shared responsibility frameworks: IaaS requires client management from the guest OS up through the application stack. PaaS isolates client responsibility to application development and data schema management while vendor manages OS and runtime platforms. SaaS limits client interaction to user management and data settings while the provider handles all underlying infrastructure and application logic.
