CompTIA Cloud Essentials+ (CLO-002)Cloud ConceptsHard
A cloud architect is designing a solution for a critical financial application that requires the lowest possible latency and the highest level of isolation for its infrastructure. The company also has strict regulatory requirements that mandate data residency within its own data centers. Which cloud deployment model is most appropriate?
- ACommunity Cloud
- BHybrid Cloud
- CPublic Cloud
- DOn-Premises Private Cloud
Show answer & explanationAnswer & explanation
Correct answer: D. On-Premises Private Cloud
An on-premises private cloud provides the highest level of isolation, direct control over the infrastructure (for lowest latency and specific hardware), and ensures data residency within the company's own data centers, meeting strict regulatory requirements. This model offers complete control over the entire stack.
Why the other options are wrong
- A. Community cloud shares infrastructure among several organizations, not providing the necessary isolation and control for a single entity's critical application.
- B. Hybrid cloud involves some public cloud components, which would violate the strict data residency and isolation requirements for the critical application.
- C. Public cloud lacks the required isolation, direct control, and data residency guarantees for this scenario.
On-Premises Private Cloud
A cloud deployment model where the cloud infrastructure is provisioned for exclusive use by a single organization and is hosted within their own data center.
- Highest level of control and security
- Ensures data residency
- Requires significant capital expenditure and operational management
