CompTIA Cloud+ (CV0-004)Cloud ArchitectureMedium
A company is migrating a legacy application to the cloud. This application requires specific, certified hardware configurations and operates under a licensing model that ties software licenses to physical CPU cores. To comply with licensing agreements and ensure performance, which cloud compute model should be recommended?
- AOn-Demand Instances
- BServerless Functions
- CDedicated Hosts
- DSpot Instances
Show answer & explanationAnswer & explanation
Correct answer: C. Dedicated Hosts
Dedicated Hosts provide physical servers with specific configurations, allowing customers to use their existing per-socket or per-core software licenses and meet compliance requirements for specific hardware.
Why the other options are wrong
- A. On-Demand Instances are shared virtualized instances and do not guarantee dedicated physical hardware for licensing compliance.
- B. Serverless Functions abstract away the underlying hardware entirely, making them unsuitable for applications with physical core-based licensing requirements.
- D. Spot Instances are highly discounted, interruptible instances and are not suitable for stable, licensed legacy applications.
Dedicated Hosts
Dedicated Hosts are physical servers in the cloud provider's datacenter that are entirely allocated to a single customer. They provide granular control over instance placement and are ideal for meeting specific licensing requirements (e.g., per-core, per-socket) and compliance needs.
- Physical servers dedicated to one customer
- Allows use of existing software licenses (per-core, per-socket)
- Provides visibility and control over host configuration
- Useful for regulatory compliance and specific hardware needs
- More expensive than shared instances
Memory trick: Dedicated Hosts are your private 'hotel room' in the cloud, perfect for picky software licenses.
