CompTIA Cloud Essentials+ (CLO-002)Cloud ConceptsHard
A manufacturing company is exploring cloud solutions to host its critical production control system. They require guaranteed access to specific physical hardware resources, extremely low latency, and absolute data isolation to meet stringent regulatory requirements. Which type of cloud deployment model would be the MOST suitable choice?
- APublic Cloud
- BHosted Private Cloud
- COn-Premises Private Cloud
- DHybrid Cloud
Show answer & explanationAnswer & explanation
Correct answer: C. On-Premises Private Cloud
An on-premises private cloud offers the highest degree of control, absolute data isolation, and the ability to guarantee access to specific physical hardware resources and extremely low latency, which is crucial for critical production control systems and stringent regulatory compliance.
Why the other options are wrong
- A. Public cloud would not meet the requirements for absolute data isolation, guaranteed physical hardware, or stringent regulatory needs due to multi-tenancy.
- B. Hosted private cloud offers dedicated resources but is still physically off-premises and managed by a third party, potentially introducing latency and reducing the absolute control needed for 'specific physical hardware'.
- D. Hybrid cloud would still involve some public cloud components, which don't meet the 'absolute data isolation' and 'guaranteed physical hardware' needs for critical systems.
On-Premises Private Cloud
A private cloud deployment where the entire cloud infrastructure, including hardware and software, is located within the organization's own data center and managed by their internal IT staff.
- Highest level of control, security, and data isolation.
- Guaranteed access to specific physical hardware.
- Lowest latency for internal applications.
- Full responsibility for management, maintenance, and costs.
Memory trick: On-prem is your fortress, Public is a shared city.
