CompTIA Cloud+ (CV0-004)Cloud ArchitectureMedium
A cloud architect is designing a new application that will process sensitive customer data. The application requires dedicated compute resources to meet strict compliance regulations and performance isolation requirements. Which compute model should the architect recommend?
- AServerless Functions
- BVirtual Machines
- CContainers
- DDedicated Hosts
Show answer & explanationAnswer & explanation
Correct answer: D. Dedicated Hosts
Dedicated Hosts provide physical servers with dedicated compute capacity, which is essential for meeting stringent compliance and performance isolation requirements for sensitive data. This model ensures no other tenants share the underlying hardware.
Why the other options are wrong
- A. Serverless functions are highly shared and do not offer dedicated physical isolation.
- B. Virtual Machines are typically multi-tenant unless specifically configured on dedicated hardware, which is less precise than a Dedicated Host.
- C. Containers run on shared hosts by default, offering no physical isolation from other tenants.
Dedicated Hosts
A cloud compute model where customers provision entire physical servers dedicated solely to their use, providing maximum isolation and control.
- Offers single-tenant physical server isolation.
- Ideal for strict compliance, licensing, and performance requirements.
- Higher cost compared to shared virtualized resources.
Memory trick: Dedicated hosts ensure your data is 'Dedicated' to its own 'Home' for ultimate 'Isolation'.
