Overview
This section covers what cloud computing is, how responsibility is shared between customers and cloud providers, why organizations use cloud services, and how IaaS, PaaS, SaaS, and serverless models differ.
Core Concepts
- Cloud computing delivers compute, storage, networking, and application services over the internet using provider-managed infrastructure.
- The shared responsibility model changes by service type: customers manage more in IaaS, less in PaaS, and least in SaaS.
- Public, private, and hybrid clouds differ by ownership, access, control, and integration requirements.
Exam Tips
- Use the service model to decide customer versus provider responsibility.
- Look for workload ownership, regulatory control, and connectivity clues when choosing public, private, or hybrid cloud.
