CompTIA Cloud+ (CV0-004)Cloud ArchitectureHard
A company is migrating a legacy application to the cloud. The application is tightly coupled to the underlying operating system and has specific licensing requirements that mandate dedicated physical hardware. Which compute model would satisfy these constraints while still leveraging cloud infrastructure?
- AVirtual Machines on shared tenants
- BContainers on managed services
- CServerless Functions
- DDedicated Hosts
Show answer & explanationAnswer & explanation
Correct answer: D. Dedicated Hosts
Dedicated Hosts provide physical servers for exclusive use, allowing customers to meet specific licensing requirements that are tied to physical cores or sockets, while still benefiting from cloud infrastructure management and billing.
Why the other options are wrong
- A. Virtual Machines on shared tenants do not provide dedicated physical hardware and would violate licensing requirements tied to physical cores.
- B. Containers run on virtual machines or dedicated hosts, but the container model itself doesn't guarantee dedicated physical hardware for specific licensing needs.
- C. Serverless functions abstract away the underlying infrastructure entirely and do not offer control over dedicated physical hardware.
Dedicated Hosts
A cloud compute model where customers provision and use an entire physical server, dedicated to their account. This allows for greater control over instance placement and helps meet specific enterprise licensing requirements or compliance needs.
- Exclusive use of a physical server
- Supports 'bring your own license' (BYOL) for certain software
- Provides hardware isolation for security and compliance
- Higher cost than shared instances
Memory trick: Dedicated Host: your own server, your own rules.
