CompTIA A+ Core 1 (220-1201)Virtualization and Cloud ComputingHard
A company runs sensitive financial workloads on its own privately owned and managed cloud infrastructure. For a separate, non-sensitive analytics workload, the company wants to temporarily use a public cloud provider's compute resources only during periods of peak demand, while keeping the private and public environments interconnected. Which cloud deployment model does this scenario describe?
- APublic cloud
- BHybrid cloud
- CCommunity cloud
- DPrivate cloud
Show answer & explanationAnswer & explanation
Correct answer: B. Hybrid cloud
A hybrid cloud combines private and public cloud infrastructures that remain interconnected, allowing workloads such as cloud bursting to move between them based on demand while sensitive workloads stay on the private side.
Why the other options are wrong
- A. Public cloud alone doesn't account for the retained private infrastructure for sensitive workloads.
- C. Community cloud is shared among organizations with common concerns, not what's described here.
- D. Private cloud alone doesn't account for the temporary use of public resources.
Hybrid Cloud
A cloud deployment model that combines private and public cloud infrastructures, interconnected to allow data and application portability between them.
- Enables 'cloud bursting' to handle demand spikes
- Sensitive data can stay on private infrastructure
- Requires reliable connectivity between environments
Memory trick: Hybrid = 'Half private, half public, bridged together.'
