In the public cloud model, which party owns the physical infrastructure?
Show answer and explanation
Answer: C
By definition, the public cloud provider owns and operates the physical estate — datacenters, servers, network gear, power, cooling — and rents out access to virtualized capacity on it. For Azure, that owner is Microsoft. The customers are tenants consuming shared resource pools, and that provider-ownership is precisely what enables the economies of scale that make public cloud cost-effective.
Why the other options are wrong
- A. Public cloud customers consume rather than own the physical infrastructure; ownership by the provider is a defining trait of the model.
- B. Colocation vendors exist, but for Azure specifically Microsoft owns and runs the datacenters.
- D. Government agencies are customers of the general public cloud like anyone else; even sovereign offerings such as Azure Government are operated for and screened by government, but ordinary public cloud infrastructure belongs to Microsoft.
