Microsoft Azure Fundamentals (AZ-900)Describe cloud conceptsHard
A company is considering adopting a cloud model where they purchase and manage their own physical servers, storage, and networking equipment, but host it within a third-party data center. They want to leverage the data center's infrastructure (power, cooling, physical security) while maintaining full control over their hardware and software stack. Which cloud model does this scenario describe?
- APublic Cloud
- BHybrid Cloud
- CCommunity Cloud
- DPrivate Cloud
Show answer & explanationAnswer & explanation
Correct answer: D. Private Cloud
This scenario describes a private cloud. Even though the hardware is housed in a third-party data center (co-location), the company still owns and exclusively manages its own physical infrastructure and software stack. The key is exclusive use and full control, regardless of physical location.
Why the other options are wrong
- A. Public cloud involves shared, provider-owned infrastructure.
- B. Hybrid cloud combines public and private, which isn't the primary setup here.
- C. Community cloud is shared among specific organizations, not exclusive to one company.
Private Cloud
A cloud computing environment dedicated exclusively to a single organization. It can be physically located on the company's premises or hosted by a third-party provider (co-location) but is not shared with other tenants.
- Exclusive use by one organization.
- Can be on-premises or off-premises (co-located).
- Offers maximum control over infrastructure and data.
- Higher capital expenditure and operational burden than public cloud.
Memory trick: Private is yours, Public is shared, Hybrid is both.
