An IT administrator is cataloging company IT projects based on their cloud management boundaries. Match each cloud deployment scenario on the left to the corresponding cloud service model on the right.
- Migrating a legacy database to cloud virtual machines where internal IT installs operating system updates, configures firewall rules, and manages the database engine.Infrastructure as a Service (IaaS)
- Deploying custom web API code into a managed runtime stack where the provider manages the web server hardware, operating system, and framework.Platform as a Service (PaaS)
- Subscribing to a cloud-hosted productivity suite where the vendor manages infrastructure, server operating systems, security patches, and application software.Software as a Service (SaaS)
Cevap
The database cloud virtual machine scenario matches Infrastructure as a Service (IaaS). The custom web API code deployment scenario matches Platform as a Service (PaaS). The cloud-hosted productivity suite subscription scenario matches Software as a Service (SaaS).
Each deployment scenario aligns with a specific cloud service model according to the shared responsibility matrix: managing operating systems on virtual machines corresponds to Infrastructure as a Service (IaaS); uploading custom code to a vendor-managed execution stack corresponds to Platform as a Service (PaaS); and utilizing web-accessible applications fully maintained by a vendor corresponds to Software as a Service (SaaS).
