What it means
The exact responsibility boundary differs by service. Database, analytics, AI, container, and serverless offerings expose different controls and evidence.
Why it matters
Teams can reduce administrative burden with managed services but may also lose familiar controls or misunderstand what the provider actually operates.
Practical focus
- Document the responsibility boundary for each service
- Review default settings, logging, backup, and network exposure
- Monitor provider changes and deprecations
Common mistakes
- Assuming managed means secure by default
- Applying virtual-machine controls to services without hosts
- Using services before understanding data and identity behavior
